Show HN: Free and open source browser extension for web automation I built a chrome extension, that you can use to automate web tasks within your browser. No need of any separate backend. The extension is standalone and you can use it for free. It also support browser built-in models (like gemini-nano), which you can use for basic tasks like summarizing. Please have a look at Waffy.io. Also drop your honest review. Contributions are always welcome... Thanks https://bit.ly/4pjNOu5 July 14, 2026 at 02:19AM

Show HN: Sx 2.0 – Share AI skills with your team through a Dropbox folder https://bit.ly/4gUVTDJ

Show HN: Sx 2.0 – Share AI skills with your team through a Dropbox folder Hi all, author here. SX started as a CLI to let developers share skills across AI clients without having to rely on git for storage. This allowed sharing at the Repo/Team/Org and Personal level. However, the more we spoke to users the more we realized that non-technical users were actually using skills more and more but they had no way to share. And there was no way you were going to get your legal team to install and learn git. SX 2.0 is targeting non-technical teams by adding a native Mac, Windows and Linux app. Our vault format was reworked so it can be used directly as a claude or codex plugin. And by storing your vault in Dropbox, Google Drive, iCloud or others you can be up and sharing in under a minute. 2.0 also adds an extension system with extensions that manage Skill Evals, LLM de-duping, metics and much more https://bit.ly/4gUVTUf . It's Apache-2.0 and you can download it here https://bit.ly/4gy0TxP . https://bit.ly/4aSeg8t July 14, 2026 at 12:26AM

Show HN: ContextVault – Shared memory layer for your AI and your team https://bit.ly/4ph3IFI

Show HN: ContextVault – Shared memory layer for your AI and your team Hi HN, I'm Kevin. I built ContextVault because I kept running into the same problem with AI tools. Every project accumulated prompts, coding conventions, architectural decisions, examples, and other pieces of context that made the models significantly more useful. The problem was that this information quickly became fragmented. Some lived in ChatGPT Projects, some in Claude, some in Markdown files, some in internal documentation, and some only existed in previous conversations. Late last year, I realized several people on our team were solving the same problems independently because previous work was difficult to discover. I assumed this problem existed in other large organizations, so I started experimenting with a shared context store. I started with a local proof of concept and a rough MCP server. If I asked questions like "have we done this before?", the AI could search the database and find the most relevant item to review. If a conversation produced something worth remembering, I could say "save what we learned to the vault." After using that workflow for a few months, I found myself relying on it every day. I decided to make it available to others. I've never built a product before, and I thought it would be a valuable learning exercise to do. ContextVault is a a product for storing and organizing reusable context that can be shared across people, projects, and AI tools. Instead of copying the same instructions into every conversation, you can store them once and retrieve them through our MCP server. It is not limited to any one AI client. Your team can use ChatGPT, Codex, Claude, and Gemini and save/read from the vault all the same. It currently supports: - OAuth support for GitHub, Google, Microsoft, and GitLab - Structured context records with metadata - Multi-user organizations with role-based access - MCP server for all AI clients that support MCP - Organization-scoped storage keeps tenant data separated - Group visibility rules decide which memories each member can search - Authenticated MCP access ties every request back to a real user and workspace - Feedback signals can be captured now and used to improve ranking later - Supports desktop versions of AI clients, not just their CLI versions (mobile app support should also work) The backend is built with PostgreSQL, pgvector, Node.js, and TypeScript. The frontend uses Next.js, React, Tailwind CSS, and shadcn/ui (frontend is not my strong suit, please be kind). Authentication is handled with Clerk and billing with Stripe. I started building this for my own workflow, but after relying on it for several months I decided to make it available to others. We soft launched a few weeks ago, and I find it useful as a daily tool. Essentially, ContextVault offers a way to track memories and context, distribute them instantly to your team, and help reduce duplicated work. I'd be interested in feedback on a few things: - How are you managing reusable AI context today? - Are you relying on similar tools, or do you keep everything in Git or Markdown? - If you've built something similar, what did you learn that you would do differently? You can see the product here: https://bit.ly/4hgU2ca https://bit.ly/4hgU2ca July 14, 2026 at 12:22AM

Show HN: Hologram, photo management and culling built with Tauri https://bit.ly/4vmbWhb

Show HN: Hologram, photo management and culling built with Tauri Hello Hacker News photographers! Yes, this is essentially my take on photo colling and management, similar to the features that Lightroom and Darktable already have. Because I shoot in JPEG+RAW, my workflow looks like me going through my JPEG images and then eliminating the JPEGs I don't like afterwards in addition to their corresponding RAWs. At least on my old MacBook, the JPEGs were faster to load than the RAW photos (probably a combination of CR2, the file my EOS 40D, not having embedded JPEG previews and my buggy macOS version). Hologram would be my way of making this workflow easier to do, especially with keyboard shortcuts. I also never liked the star-based system on Lightroom or Darktable, so I implemented Pick and Reject instead (which matches what I would otherwise do with deleting photos to my system trash when I cull in the Finder app) Anyways, with my new R7 I found that bursts got more annoying to cull so I decided to create autocull on Hologram as well. This would analyze your photos and help you suggest which photos in a burst to keep, or which photos to keep in a shoot in general. Currently, this is not notarized or whatever, but let me know what you guys think. https://bit.ly/3QR13Gd July 13, 2026 at 12:10AM

Show HN: Levee – a self-tuning circuit breaker and concurrency limiter for Go https://bit.ly/4yi25vA

Show HN: Levee – a self-tuning circuit breaker and concurrency limiter for Go Rate limiters and circuit breakers work wonderfully well when they’re configured for the load and available capacity. But load, capacity, and latency drift over time, and keeping those settings current requires continuous effort. So I built Levee to be a hands-off, adaptive, easy to configure traffic governor. Levee is configured with a success-rate target and timeout. It then continuously monitors the workload performance characteristics to detect downstream capacity exhaustion or failures. It can also spot a surge from growing concurrency before failures arrive. It runs in-process, uses a small, fixed amount of memory, has zero dependencies, and processes millions of requests per second. In a deterministic 10-node mesh simulation, Levee outscored carefully tuned static rate limiters/breakers deployed throughout the mesh, while recording fewer failures and no node crashes. https://bit.ly/4bozc75 July 12, 2026 at 02:22AM

Show HN: Krbn, a pencil-style 3D renderer with SVG output https://bit.ly/4wCDHmP

Show HN: Krbn, a pencil-style 3D renderer with SVG output Krbn is a childhood dream I finally got to research & prototype (from a hospital bed of all places), during a medical break from my normal work: a rendering engine that draws 3D scenes the way a technical sketch artist would. It asks "which lines would an artist draw and what would they leave out?" Basically strokes are derived exactly from geometry, rather than sampling. True conics, quartics etc. So there is no shading model, it's replaced by hatching (either flat or following the curvature of the object). There's no alpha channel, the gaps between lines do the work as on paper. It introduces hand-wobble (which is seeded, so animations don't "boil" between frames) and various other things; the example gallery shows more. With all that, output is byte-stable, i.e. two successive renders will cause zero changes in Git. Full disclosure, since it matters here: this was built with significant AI assistance, deliberately, as an experiment in how far a carefully directed human-AI collaboration can get on a hard rendering problem. The briefs are in the repo - judge for yourselves. Gallery: https://bit.ly/4wtPnrK The longer story: https://bit.ly/4wtPiEs... P.S. There's no pitch here... just an invitation for a weekend skim over something I find fascinating. https://bit.ly/4wwROtF July 11, 2026 at 06:51AM

Show HN: Fortress – Give your agents unlimited access to the web https://bit.ly/4gq4tdf

Show HN: Fortress – Give your agents unlimited access to the web i personally believe that the internet is the best thing we've ever built, and arguably, nothing we made before comes close. now agents can use it too, but the web treats them as second-class. every agent works for a person, so whatever it keeps from agents it keeps from us. we believe that if we let them in, each of us gets the whole of what we built, a thousand times over. and to add to that, democratization of tools that allow this is essential, despite the fact that there will always be bad actors. so, we built fortress, which is an open-source stealth chromium engine. it is a recompiled fork that corrects the browser fingerprint from inside the engine: the surfaces bot detectors read, canvas, webgl, audio, fonts, navigator, and about thirty more, are patched in chromium's c++, with no javascript layer sitting on top for a page to catch. it beats the hardest bot detectors on the planet, works fully locally and is open source for y'all to see the patches we've made. and it comes with an mcp, so you can use it with your agents without having to do any major setup or code changes. do give it a try here! https://bit.ly/4wnq6PW July 10, 2026 at 01:57AM

Show HN: I built a free app for New Yorkers to save money on groceries https://bit.ly/3STjlqT

Show HN: I built a free app for New Yorkers to save money on groceries I built this because I see that grocery savings are achievable in NYC. People usually just go to the store they're used to going to, and it's rarely worth the effort of combing through card cashback, weekly coupons, CPG rebates. Most people leave real money on the table by not stacking them, and even more don't even know that these deals are out there.... so I built a way to automate it. You can use it for free, no login, currently NYC-only with ~690 stores. I built it so that you just search whatever you want (use commas if you want to search multiple items). Or - use the AI tool to help shop for you. If you're curious, it's powered by a trained LLama model. Honest limitations are coverage and freshness. Id love some feedback on where the data looks wrong or is stale. Question for the room - what to prioritize if you're working with messy, multi-source retail/pricing data? Is freshness or coverage the top priority if you cant get a uniform response from every source? curious on what to prioritize here. https://bit.ly/4fqTaR4 July 10, 2026 at 01:17AM

Show HN: Frugon – Find which LLM calls a cheaper model could handle (local, MIT) https://bit.ly/3SMUCo8

Show HN: Frugon – Find which LLM calls a cheaper model could handle (local, MIT) I started leaning in on AI heavily this year, as I wanted to get more done autonomously, but then my token usage climbed dramatically to the point where my weekly quota would run out before the end of the week, sometimes a couple of days into the week. I realised I had to do something about it else I'd have to double my spend. So I decided to start tracking my cost per task type. This revealed that a lot of my spend went to searches/scans or simple things like scouting tasks. I then decided to turn this into a simple CLI tool that can be used to read your OpenAI-style logs locally, and analyze the cost and compare this spend to other models, then show you how much you could potentially save by switching those calls to a cheaper model. When you run analyze you get an offline estimate priced against LiteLLM and gated by LMArena tiers. The general savings bands come from the research published by RouteLLM; but you can confirm this yourself using 2 commands --measure (shows the prompt-response output side by side) and --judge (a model chosen to do the comparisons). These send a sample of the prompts from the logs to the candidate models - either the default choice or set by you. This call goes directly to the model provider (never through me) as any normal LLM call would, and the response is shown and judged to either be better or worse or a tie. It's deliberately small, because I tend to over complicate/think things sometimes: analyze + capture + a few commands, doing three jobs. Cost, quality visibility, routing recommendation. Nothing is hosted. capture is an optional local proxy on your own machine, and there's no endpoint in the path of your data. You can confirm this by checking the source. I included a demo so you can check out the output. It has a synthetic 56k call log (a month's worth) showing how costs can drop from $549.46 to $343.91 a month. A 37.4% saving. Try it: uvx frugon analyze --demo or uv tool install frugon Then point it at your own logs. All feedback is welcome, especially any on the routing/quality logic, or anything else, good or bad. https://bit.ly/4ybqv9T July 7, 2026 at 01:20PM

Show HN: Autoops – Multi-region data and service mesh operated by a Makefile https://bit.ly/4vkxzOW

Show HN: Autoops – Multi-region data and service mesh operated by a Makefile Hi HN, Stefan here. autoops is an infrastructure automation framework I have been using at my previous company and is now opensourced. It has been the base layer running various products and projects, and also for quickly standing up client infra. It works with Debian-based systems (apt) and sets up a WireGuard mesh with peer discovery and built-in DNS (Wesher), a distributed S3-compatible object store (Garage), and a reverse proxy and load balancer (Traefik). It supports service autodiscovery (Traefik-kop) and can be horizontally scaled to up to 150-200 nodes. As a classical example of "roll your own k8s subset using scripting", it is not yet fully integrated and currently, you need 1) to define at least a PyInfra inventory, 2) depending on whether you run containered services, a Docker Compose file, and 3) for horizontal scaling with autodiscovery, a Traefik config. The PyInfra scripts are put together in a Makefile, but that is pretty self explanatory. autoops doesn't trust supply chains, so you need to out-of-band put a couple of binaries in the general assets/ folder, and if you do containers, provide a path that contains directories named after each service and holding its Dockerfile and other build assets. Also, it's almost arm64 compatible (needs binaries for Docker and the crowdsec bouncer), can do NAT traversal (using my fork of Wesher), and container draining (using docker-rollout). Feedback is welcome. https://bit.ly/4p3NmQE July 6, 2026 at 10:59PM

Show HN: Logo Design for Busy Founders https://bit.ly/4eM8SGj

Show HN: Logo Design for Busy Founders General purpose illustration tools like adobe illustrator or affinity have a great amount of flexibility but come at the cost of complexity that isn't needed for a logo design tool. So I trimmed down the fat to a minimal set of 10 tools acting on a logo grid, when combined together makes it easy to build quite a surprising variety of logo marks pretty fast. This was a very interesting project unlike most of the work i've done over the years, this iteration (the 4th) came from progressively whittling down (vs up) affordances, if a combination of tools could do what one did, it was cut, if that tool didn't seem to behave cohesively with the rest (perhaps potentially breaking the user's mental model of the editor) it was cut. Initially i had features like layers, multiple fill colors. Naively i felt my goal was to build a minimal set of tools that achieved "logo-completeness", but i realised that would just give me a terrible Illustrator clone vs balancing learning curve to expressivity. There's still some wonky behaviour related to selecting/cutting, this will be fixed once I can put a finger to what this wonkiness is actually. It exports to SVG, transparent PNG, PSD and more. https://bit.ly/4y6kjA6 July 5, 2026 at 11:50PM

Show HN: Tracking how much of the HN front page is AI-generated https://bit.ly/3R3uswC

Show HN: Tracking how much of the HN front page is AI-generated For the past few months, I've been sending every story that reaches the HN front page through Pangram's AI detector and noting the scores. The reason I made it is that I kept noticing posts that sounded like AI-generated to me. Sometimes the comments pointed it out, sometimes a post was near the top all day and no one said a word. I wondered if the share was really increasing or if I was just primed to see slop everywhere. How it operates: The site identifies the top 30, gets each article, and evaluates the text using Pangram. Besides the live front page view, there are daily and monthly trends, with leaderboards for domains and authors that keep scoring high. I personally find it quite helpful as a sanity check on my own intuition before declaring something AI in the comments. 6,500+ stories in, it turns out the front page is still very human after all, which is the part that shocked me the most. A fraction of 13% of stories were AI flagged over the last 30 days. That's slowly ramping up (roughly a point higher than the previous month) but still not close to the feeling of 'everything is slop now' I had. At the moment it's 1 flagged story out of 30. The flagged ones still manage to get by quite well. One of them is at #6 today with 545 points and a 99% score, and the discussion section is divided on whether it's AI or not. Standard disclaimers: a detector score is not a piece of evidence, false positives do occur, and a high score can also be the result of a human coming up with the ideas and then using a model for the prose. To me, it is an invitation to examine the matter more closely rather than a judgment. Feel free to ask me anything about the setup. And yes, I ran this post through the detector before submitting it. https://bit.ly/4fkFQh2 July 5, 2026 at 08:17AM

Show HN: Reading Assistant Physical Books Meta RayBans Reading technical books is hard. Unknown words, confusing phrases, and misunderstood concepts requires opening your phone, starting Claude, and working with Sonnet through a series of exchanges, before finally getting it. Focusing back on reading after such a context switch can be difficult. Repeated multiple times and your attention span is gone. Fix: An assistant understands your book deeply and answers inquiries through voice while you read, side-stepping the current process entirely. All you have to do is: - Upload a PDF version of your physical book and start reading - Say "Hey Lumos" along with your inquiry ("why does det(A) mean the matrix loses volume?") - Assistant researches the contents of the book and responds - Continue reading until you need help again It's in extreme beta but works well enough where I can't read a book without it.

The project started from my personal needs of simple archiving with structure and moved to product design/MVP exercise. I am longtime HN user, and the most value I got in years of reading is always deep in the comments section. For HN Capcat uses the official API, with rate-limits, identifies honesty with clear user agent and skips paywalled content. All usernames are anonymized with a link to the user profile. The content is delivered in Markdown format (Obsidian ready with frontmatter) and optional HTML with dark/light themes. Every source has its own YAML config file for separate control and PDF size limiter. In the folder users have an option to change the HTML theme with a minimal CSS design-system. Please consider that my focus as a product designer is in UX. I have enough of a general culture and software development principles but the code is not validated, and my decisions in building may have a limitation. Feedback is welcomed.

Show HN: C++, Java and C# light-weight-logger https://bit.ly/4biJd5A

Show HN: C++, Java and C# light-weight-logger This is a library I've been working on with versions for C++, java & C# where you make custom formats and Log based on them, for example you could make an ERROR Like this: [ERROR] [date, time-stamp, time-zone]

(file:thread-ID:line) but you would write it like this: // define the master format master_style = "%C[%N]%c%S%G[%D %T %Z]%c %M %G(%F:%t:%L)"; // tell the logger what colour to use for a given name logger.add_format("ERROR", master_style, Colour::RED); so now the [ERROR] part will be red, the time area will be grey, and the location grey, but you could really make any style you wanted. And once you have a master format you could also add different types of logs: logger.add_format("SUCCESS", style_minimal, Colour::GREEN); logger.add_format("INFO", master_style, Colour::CYAN); logger.add_format("WARN", master_style, Colour::YELLOW); also the %S we put in there is actualy a colum padder so you logs will be inline: [INFO] [16/06/2026 10:58:00 AUS Eastern Standard Time] Initializing core subsystem components.

Show HN: Xenoeye – analyze network without AI using netflow, PostgreSQL, Grafana https://bit.ly/4eKAKt2

Show HN: Xenoeye – analyze network without AI using netflow, PostgreSQL, Grafana Sorry for the slightly truncated title. It should have been "Network traffic analysis and monitoring without AI, using netflow-family protocols, PostgreSQL or ClickHouse, Grafana, and some scripts". In 2026, it might seem a bit presumptuous to announce AI-free software on HN. But building a netflow analyzer manually is no less presumptuous! There are quite a few xFlow analyzers out there these days, and I'm constantly reminded of this. But I think there's always room for an alternative approach. After all, that's how software evolves, isn't it? So, how does xenoeye differ from popular (at least from popular open source) analyzers? - The analyzer has a feature called "monitoring objects". For some reason, open-source analyzers rarely use this feature, while commercial ones do. The monitoring object can be a subnet, autonomous system, geo-object (data on geo and AS are taken from external databases), application traffic (protocol, TCP/UDP ports, etc.), VLAN, etc. Almost everything in flow records can be used as a filter for a monitoring object. Of course, object filters can be composite - the classic operations AND, OR, NOT are supported. The analyzer contains a tiny virtual machine that matches each flow to an object. - We don't store all flows. At least for now. It may seem strange, but this is an important feature, especially for large networks. We store aggregated data on monitored objects. The user chooses what to store. It could be just in/out, top talkers, top protocols, etc. The time for which to aggregate data is also specified by the user. Aggregation occurs inside the analyzer. We use a fast trie-based in-memory db. Because of this, the analyzer can process flows quite quickly (hundreds of thousands of FPS per vCPU) and export a measured amount of information to the database. You can easily use even vanilla PostgreSQL. Or ClickHouse with compression. The analyzer is not very resource-intensive; small network traffic can be processed on low-end hardware or in a VM with a small amount of memory. Or you can process large network traffic on a single server, without building clusters. I know of installations with multi-terabit traffic and hundreds of MOs on a single virtual machine (of course they have a high sampling rate on their routers). - We can monitor traffic thresholds being exceeded using moving averages. That is, as soon as an excess is detected, an external script is launched at the same second (actually even faster). This feature is typically used to detect volumetric DoS/DDoS attacks. The scripts announce BGP Blackhole or BGP Flowspec and notify users via messenger. - We don't have our own visualization utility; we use Grafana. Grafana works with PostgreSQL out of the box, although some complex time-series charts require some tinkering with SQL queries. Ok, it's a controversial decision, but users (and we ourselves) are putting up with it for now. I tried to describe the rest in the documentation. Yes, this isn't the first time I've tried to announce this project on HN, and I'm under no illusions - for some reason, hackers aren't very fond of this type of software. Perhaps everyone thinks that the production of netflow analyzers is too boring a matter, there is nothing to discuss. However, if anyone is interested, it would be great to get feedback. What would you do differently than it was done and why? What do you like most about your favorite analyzer that you can't find anywhere else? How did you even see this post? This isn't AI or even a Rust-related thing https://bit.ly/4aqB92t June 29, 2026 at 10:00PM

It develops a rich understanding of your needs and goals by constantly viewing your activity. Don't worry, none of your personal data ever leaves your computer since all the models run locally. I think it's something cool to show a feature that local agent systems can do that cloud systems can't.

Show HN: Engye – transfer files between any two devices by scanning a QR code https://bit.ly/3SzSShN

Show HN: Engye – transfer files between any two devices by scanning a QR code Early in April I needed to print some tax forms at the library, first time in forever, and I began to wonder: what's the easiest way to get a file onto a public computer? There are many ways, but most of them involve creating an account somewhere or plugging in a thumb-drive. I use a password manager, so my passwords are long and complicated, not easily typed. I don't want to plug anything into a public computer, nor do I fancy uploading my taxes to some random website. I thought about what a helpful product would looks like, and in about an hour I spun up the first version, https://bit.ly/4oSooDD... : a static Vite TS site, hosted on GitLab Pages, which uses a QR code to connect two instances of the website using WebRTC. Now all I had to do was navigate to a URL on the library computer, scan the generated QR code, choose the tax file on my phone, and the library computer instantly downloaded it. After the library trip, I looked further into this space, and found that no one solved the specific combination of cross-network, no install, no account, no cloud. Snapdrop and PairDrop are similar sites but are LAN-only or require a public room. LocalSend requires installing software on both devices, which makes that impractical for public devices. And other solutions were either hardware locked (AirDrop, Quick Share), required uploading files to the cloud (Google Drive, Dropbox), or sent data through their own servers (Wormhole). So with some determination, night and weekend coding, and plenty of scope creep, we have... Engye, pronounced "an-jee" like the name Angie, is available at https://bit.ly/3SAOXRQ and can be used to do a whole lot with just a QR code and no accounts: - send a file: users download it from your browser tab - collect files: users upload files to your browser/desktop - clipboard share: users share a single text box, good for sharing short text - virtual drive: Engye Drive allows you to create and attach a virtual thumb drive Think I may have gotten carried away with that last one. ¯\_(ツ)_/¯ My honest hope with this was to make thumb drives obsolete for MOST uses. (Almost named this project "We Break Thumb(drive)s" as a reference to the Simpsons, but couldn't get the name to work out.) It's 2026, it should be trivially simple to transfer a document from one device to another! So I decided to make this obvious and simple project, and I think it can be quite helpful for a lot of people. It's not practical to use this app for transferring 4K movies (a large file would crash the browser, since we load the data into memory twice), but for most people's use-cases of transferring a handful of pictures and documents here and there, this project should simplify things a lot. Engye Drive was a fun, nerdy addition after I got the basics working. I really wanted to be able to connect a virtual drive just by scanning a QR code. The web app provides full access to an Engye Drive, and by installing an npm package you can even auto-mount the drive in Finder or Explorer. For security the app uses AES-256-GCM and new IV per each request, so your data is always encrypted between browsers. If TURN or other relays are used, they never see the plaintext, so you're safe from a MITM attack. The encryption key is in the QR code, so only people who scan your code can share data with you. There are no accounts, and closing the browser terminates the connection. If you do need a longer session or offline usage, you can install Android/iPhone apps that run Engye in the background. This project also served as a personal experiment in agentic coding. I designed the app, instructed Claude to implement it, then iteratively developed the app by chatting with Claude over the course of about three months. Code’s on GitLab, AGPL-3.0 — free to use and self-host: https://bit.ly/4gaM43X Happy to hear what others think. https://bit.ly/3SAOXRQ June 28, 2026 at 01:36AM

Show HN: The TypeScript Semantic Layer for ClickHouse I've built a type-safe semantic layer in code, for ClickHouse. If you're building analytics off ClickHouse in TypeScript, I would love your feedback. With hypequery there is no platform to adopt, no YAML sprawl. It runs where your app runs. Key features: - Define metrics once, reuse them everywhere: Declare dimensions and measures in one place and then pull from the same source of truth. - Compiles to ClickHouse SQL: No service, no proxy, no extra runtime to deploy. It's a library that generates SQL and runs where your app runs. - Multi-tenancy & Authentication ready: Cross-tenant queries are blocked at the query layer, helpers to plug into your existing auth. - Agent-native: A dataset is a declared set of dimensions and measures, so it doubles as an allowlist. Includes an MCP server to hand an LLM a typed catalog to query. - Runtime HTTP entry point: serve() exposes any dataset as an endpoint, so the same type-safe definitions back your dashboards and your API. https://bit.ly/43YBtly June 27, 2026 at 10:37AM

Show HN: Hacker News on a Train Station Style Flip Board Although the page itself is more just fun to have made and look at (I like the flip sound), the fun part is how I made it to verify the (and I hate to say it) vibe host service I've been working on. The recent flip board back and forth's on Twitter (X) are what inspired me. The idea here is that people (like me or you) can create something neat like this, and others can remix it, change it and publish their own version. This is that all in action and it worked great. I wrote a blog about it (the blog is dogfooding, it's just an app hosted on quickish that uses the built in db lib). For the HN version of this flip board I use their firebase api via the built in quickish server functions that make use of the fact that the front-end can get realtime updates (now that you mention firebase) from cloud function db updates. Of course that's over-kill but I wanted to show something fun. You can remix and host your own version for free, just need a google oauth login that's it.

Show HN: DeepSeek Flash inverted the economics of agent products https://bit.ly/4vPuiIJ

Show HN: DeepSeek Flash inverted the economics of agent products There is an adversarial relationship between developers and big model labs. Model labs charged developers higher API prices to subsidize their own agent harness offerings. Think Anthropic charging 5x higher Claude API prices to subsidize consumer subscriptions. So Cursor in a way was subsidizing their own direct competitor. DeepSeek V4 Flash totally inverted this relationship. Now you have a model that beats even Sonnet in some benchmarks and is totally opensourced. Now inference providers are racing to the bottom to optimize and give cheaper hosting. Every player with a non-SOTA is now racing to swap over to stop paying the big model lab tax, even Microsoft is switching Copilot to use DeepSeek. On switching over to Deepseek: - we noticed over a 100x cost decrease while similar or better performance then Gemini 3 Flash - insane saving from the cached input tokens: $0.002/1 Million tokens - both DeepSeek Flash and GLM 5.2 are text-only models, so clearly multimodal training is not worth the additional cost. Language is just a much more efficient sparse representation of the world/reasoning than vision - we had a early bet on a text-only web agent harness, and now with DeepSeek this results in unique cost advantages. - we rewrote our harness as a callable DSL library that a model can generate code to execute on. DeepSeek has proven phenomenal on code generation to drive an agent harness. - I would highly recommend everyone to rewrite their harness to be text-only and callable via executable code leveraging DeepSeek V4 Flash. https://bit.ly/3QJXSzU June 25, 2026 at 11:56PM

Show HN: Monolisa v3 – a typeface for developers and creatives Originally we (Andrey, Marcus, Juho) built MonoLisa in 2020 as we realised there's room for a better monospaced typeface for developers.

Since then we've released a variable v2 (2022) and now we're happy to expand the typeface with a new family called MonoLisa Text. The reasoning was to cover *other* use cases beyond coding with this proportional font. We hope you give Monolisa a go as there's a free trial to try.

Show HN: Wirewright, an experimental symbolic physics environment https://bit.ly/44s0oOg

Show HN: Wirewright, an experimental symbolic physics environment The idea with Wirewright is to treat programs and algorithms as physical mechanisms, as machines or societies of machines inhabiting an immutable symbolic world, and time-step the latter to see what happens. This last part in particular reminds me of cellular automata. Said differently, in Wirewright, programs are modeled as "nouns" or "societies" of interacting "nouns" (think data structures). The world is then subjected to laws of physics -- symbolic physics; which is the only "verb" here (think function). Therefore, in Wirewright, we say that, in a sense, algorithm equals structure and the evolution of structure equals computation. I tend to shorten this to "structure is computation", but this may be incorrect if viewed in isolation. Now, I guess you're wondering what Wirewright actually is . In fact, I see the rules here state that I must tell you what Wirewright is, plainly and clearly. I will try, but beware that at the end of the day, I know as little as you do :^) My hands write, my brains ponder. It's hard for me to say definitively what Wirewright is . Please see the README for several attempts of mine to answer this question. Please see the tutorial(s) if you're interested enough to try and infer that yourself. I'm still not sure the README or the tutorial(s) are answering the exact question, though; I had no feedback yet on most of my work on Wirewright, so any feedback is welcome, other than, I guess, "I don't understand what this is"; this kind of feedback I can generate myself, no offense :^) If there wasn't a public GitHub repo and if I hadn't made a few announcements here and there already, you'd think I'm developing the project in secret. This kind of stuff is not something you ordinarily talk about, you see, especially "in the wild"; or else you'd be quickly labeled eccentric or outright crazy. Anyway. Wirewright is not a framework, not a UI toolkit, not an IDE. It's not a programming language either. I think I'm trying to explore the intersection of different things here, such as cellular automata, term rewriting, symbolic computation, dataflow, etc. I'm also prone to veering off for pages and pages into a genre one could call "folk biology"; biology and especially neurobiology is a huge inspiration for me. Inspiration doesn't mean copying or formal study, of course. In fact, if there are any biologists here, please "shut down" your eyes and ears and all other sensory organs if you decide to explore the depths of the project :^) For me, when I see something interesting in biology, I think, in excitement, "Oh, I want to do that too, I don't care how!" The project has been evolving more or less organically, along with me, so to speak, subsuming a lot of my ideas (but mostly the ideas of others; e.g., Varela, Maturana, Wolfram), and mixing them. I'd say it's a playground of mine which, over the years, has become consistent enough for me not to fear trying to tell the world about it. That is, about two years ago, Wirewright was an amorphous blob I couldn't even describe with analogies. Now I can at least try analogies. All this "symbolic physics" stuff is the product of my most recent work in recognizing where the project actually appears to be heading. Now, as a final disclaimer, please note I'm an amateur in all of the things I'm talking about, from programming to biology to philosophy. So maybe all of this is well-trodden grounds, and I'm coming up with these words and ideas for nothing, and what I'm saying is stupid. Maybe it is. Regardless, I hope at least the synthesis looks interesting to some of you, even if the exact wording and my little philosophy intermissions here and there feel a bit off. Sorry for the long text. https://bit.ly/4uOUn9i June 22, 2026 at 01:15AM

We kept running into the same issue and found there is no observability for agentic systems. We decided to take the best aspects of LangChain, LangGraph, and DeepAgents and put them into Elixir. BeamWeaver comes with an OTP-native design and: - agents and tool calling - graph workflows - checkpoints and resumable execution - memory stores - retries, fallbacks, interrupts, and human review - typed streaming events - provider adapters for OpenAI, Anthropic, Google Gemini, xAI, and Moonshot/Kimi - fake/replay models for deterministic tests We're also building observability on top of it through WeaveScope, which we'll release very soon. BeamWeaver gives Elixir teams the tools needed to build advanced agentic systems without pushing the hard parts into Python services. https://bit.ly/43Gggwv June 19, 2026 at 03:06AM

Show HN: Talos – Open-source WASM interpreter for Lean https://bit.ly/44nzPty

Show HN: Talos – Open-source WASM interpreter for Lean At Cajal (YC W26) we’re excited to share Talos ( https://bit.ly/4uIKTw4 ), an open source framework for formal verification of WebAssembly modules in Lean. AI is now writing tons of the code that gets pushed to production. As code generation gets cheaper, verification becomes the bottleneck. We believe in a future where every piece of software comes with a mathematical proof that it does what its author intended - in doing so, eliminating many classes of exploits. Talos is part of the foundation for that. Talos provides a Wasm interpreter optimized for reasoning at the binary level, together with a weakest-precondition calculus layer for proving properties about programs. Because we reason directly about WebAssembly, any language with a Wasm backend is in scope: Rust, C++, Go, C, Swift, Kotlin, Zig, C#, and many more. To make this possible, we use Lean: a programming language and theorem prover that lets you both write software and mathematically prove that it's correct - all in one system. That's what lets Talos double as both an executable interpreter and the formal object Lean reasons about. Lean also integrates with modern AI proving tools, discharging goals automatically via both proof search and direct evaluation. To see Talos in action check out a proof for Stein's GCD algorithm, implemented in the popular Rust crate num-integer: https://bit.ly/4vWWSaz... . Our roadmap: - Full Wasm coverage by first passing the official W3C testsuite, then later verifying against SpecTec (formal Wasm spec) - Arbitrary crate verification - any Rust crate that compiles to Wasm should be in scope - Building our proof library codelib, to make verifying increasingly complex programs tractable We would love to hear the community’s feedback on Talos and comments on the state of formal verification right now. Contributions are also welcome! https://bit.ly/4uIKTw4 June 18, 2026 at 02:10PM

Show HN: Reyn – local-first AI that journals and recalls your work https://bit.ly/4vb9vie

Show HN: Reyn – local-first AI that journals and recalls your work Hey HN, I built Reyn - which I like to describe as "granola but for everything". You're probably thinking another screen capture AI tool (which is true). Same as always, the biggest question that comes up is privacy, so I'll talk about that first 1. raw screen data is never stored in the cloud 2. user controlled filters are granular to the point that you're able to configure specific apps, windows, websites, or even keywords to be discarded immediately (once again never leaving your mac) and never captured down the pipeline I personally built it because I find it useful and always had the problem of organizing my day (not note taking or task management), as well as sharing context on things that just happened to go undocumented throughout my day. As I was building it I decided to go even further and see if I could collect useful insights and find room for improvements in my day to day workflow. This led to the current version of Reyn and its differentiating factor being the fact that it has a proactive layer. Most tools in this space are reactive - you ask, they retrieve. Reyn surfaces insights on its own and sends a daily recap of what you worked on, what's still open, and what deserves attention. The journal feature also lets you search across basically anything you've done on your Mac. The proactive insights work by first having you configure what your ideal workday looks like — whether that's hours worked or the type of work being done. We have a few broad categories that tasks fall under, with more customization coming. Current integrations: Obsidian (available now, improvements in progress) Gmail, calendar, web search via a floating window with some agentic functionality Notion (coming soon) BYOK for LLM API requests (on the roadmap) ... and more It's still early, but the journal and insights features are the strongest parts right now. Would love some feedback especially on the privacy model. My personal take - I think with enough safeguards in place, the data aggregated about your work is fully in your control. A lot of these data sources already store your data. If you're using Notion, Claude, or just browsing a website, that data is already being stored somewhere. Reyn is just aggregating it and putting it to work for you. Happy to answer any questions about how it works usereyn.com (public beta) https://bit.ly/3S6u4hk June 17, 2026 at 11:31PM

Show HN: Numax - a portable runtime for distributed apps Hi, over the past few months I've been working on this project: Numax is a small Rust runtime that does three things: it runs WebAssembly modules in a sandbox, has a built-in local key-value store, and syncs everything across nodes with CRDTs and gossip. Basically, you write a wasm module, run it on two machines, and they converge (I hope !). It's a decentralized system... I hope someone finds it interesting! There's a whitepaper I've put a lot into, and I think the code isn't bad either! I believe there's still room in this world for software that's fun and well made, and while building Numax I had a great time! I love Numax and I love software.

Every worktree points at the same local Postgres though, so the moment one branch runs a migration it changes the schema out from under the others. I'd end up with agents tripping over each other, or me babysitting which branch "owned" the DB at any given moment. I made this to fix it. I hope you might find it helpful too. https://bit.ly/43Bt1Z7 June 15, 2026 at 12:35AM

Show HN: Lightweight Task queue on Erlang/OTP, SQLite-backed, no overengineering Setting up Kafka or such enterprise oriented software with their clusters or dedicated servers is heavy and bothering enough that most small teams or indie hackers skip it entirely and making compromise to use in-memory queues. I wanted something in between: a persistent queue that is simple to run (one binary, which makes one sqlite db), gets real fault isolation and crash recovery due to Elixir, easy to inspect (open ezra.db in any SQLite browser and see every task), and requires no new client library - it speaks the Redis Streams wire protocol, so any Redis client in any language just works out of the box.

Show HN: LLMRender, a 10kb Markdown+LaTeX renderer for React I've been using the popular React Markdown renderers with Katex and Prism.js for rendering my Markdown and LaTeX, but was tired of having to bundle 300kb+ of min+gzip JS only for this (1.2MB+ of plain JS!). So I created a small Markdown renderer that does it all in a tiny package. I added a small playground to the homepage, please feel free to try it and let me know what you think! It's not perfect, it's definitely not "correct" in that I'm using Regex internally instead of a proper AST parser, but for my usecase and the majority of Markdown out there, this works perfectly fine (cue the StackOverflow post [1]). It's also conservative for this reason; no HTML by default, parsing wrong content produces escaped HTML entities instead of XSS.

Show HN: Manob: A social media plaform without algorithm, ads, or data-tracking https://bit.ly/4oqKyN9

Show HN: Manob: A social media plaform without algorithm, ads, or data-tracking I built Manob because I kept running into the same frustration with every major social media platform. A feed I couldn't control, content that I couldn't trust, and also a sense that I (my user data) am the product, not the user. I talked with people about these thoughts and concerns, and added my personal observation. I built this instead: - Chronological feed only. No ranking, no algorithmic shuffling. You follow people, you see all posts from all users, or choose to see posts from friends, pages you follow, and groups you are part of. - Built-in fact-checking and bias detection across text, images, and video. With Human-in-the-loop & AI combined in the process, AI detects, analyzes, and moderates posts, and every contested moderation decision is reviewed by a human against a published set of principles (not just personal judgment only). - Per chat AES-256 encryption. We designed a way that currently, if a chat is attacked and compromised, it doesn't have any effect on other chats or the platform in any way - this is constantly being improved, and security is my top priority. - No ads currently. Your data is never sold or shared (minor data is stored, all in encrypted strings) - Child safety filtering is built into the content layer - Pseudonymous mode for speaking about sensitive topics - A built-in news feed The moderation system is designed to evolve; it is more like a constitution than a rulebook. The principles are fixed but can be amended as the platform grows and severe cases emerge. The goal is to detect as accurately as possible, systematically, over claims of neutrality and move on. I'm still working on figuring out monetization. I'm thinking of contextual ads that work based on the viewing page's contents, and not on your behavioral profile. Additionally, other features like the job board and commercial tools are also an option. None of this is live at the moment, and tbh, I'm still figuring it out. The platform is currently LIVE with a small early community of active users. I'm building this solo. I'm happy to answer your questions/feedback/suggestions... https://bit.ly/3QccXtS June 12, 2026 at 06:06AM

Show HN: A Claude Code statusline that shows live World Cup scores Hey HN, I built this a side project because I'm a soccer fan that has been vibing and tokenmaxxing with Claude Code maybe too much. So, the World Cup is here and it was the perfect excuse to build and ship something from 0 to 1. Enter Claudinho, a CLI and MCP that puts World Cup scores on your terminal. No signup, no account, no data collection. The components are: - status line in Claude Code with live scores rendered always from cache, no polling. - userPromptSubmit hook so Claude gets score updates mid vibecoding session, only during a live match. - A standard MCP server and a CLI with options to see groups, standings, matches and market signal info. More details in Github. Let me know what you think, I hope you find it fun and useful! Not affiliated with FIFA or Anthropic. https://bit.ly/4fHn1W8 June 12, 2026 at 03:31AM

Show HN: Deploy personal apps with your agent via Buildy Hi HN, I'm one of the creators of Buildy. More and more people seem to be building personal software, including myself. But I keep re-implementing the same things: authentication, database setup, creating an API/MCP server to integrate them into my AI agent. We built Buildy for LLM generated personal apps. How it works: Buildy exposes an API and MCP that the agent can call with an ES module plus an optional UI and CSS. We run the ES module on a workerd isolate with a persistent KV store, then release your UI to a live URL only accessible by you. Not only that, but your app APIs are exposed securely over both HTTP and MCP so your agent can call them and use the apps you build (log a meal, create a workout plan, update a note, etc.) If your AI chat client supports MCP Apps, we can also render your app inline via an iframe. This works today with ChatGPT and Claude. Here is an app I built to track my nutrition: https://bit.ly/4v8A9Zd... ← You can actually claim this app and remix it with your own agent. To ship a completely new app, drop this prompt into your agent: Read https://bit.ly/3RTTAX3 then help me create my first app. Or check out our landing page ( https://bit.ly/4up5WUl ) to use our ChatGPT app or connect it to Claude via MCP.

Show HN: Magenta Real-Time Music Generation Locally on iPhone, Without the GPU https://bit.ly/4xqKwsU

Show HN: Magenta Real-Time Music Generation Locally on iPhone, Without the GPU Last Thursday, Deepmind released Magenta Realtime 2 , an open source music generation model. They said it could run on Mac, but not iPhone. As a v̵i̵b̵e̵ ̵c̵o̵d̵i̵n̵g̵ ̵a̵d̵d̵i̵c̵t̵ agentic AI maxxi and person who has melted iPhones before (link at bottom), I took that as a personal challenge and made it my weekend project. On Saturday, I got it to run for 10min straight on an iPhone 12 Pro from 2020 without melting the phone or - shockingly - touching the GPU. How? I chopped the model up into 5 pieces and set them each to run on different parts of Apple's system on a chip (SoC). My past experience taught me that if you can actually leverage it, the iPhone's NPU is incredibly powerful, and power efficient. If you're doing sustained real-time generation for long periods of time on a device without a fan, you gotta use the neural engine or else you will melt the device. See: https://bit.ly/4ot5K5m The Apple Neural Engine has a ton of constraints, the main one being that it only accepts fixed shape inputs, and only supports some architectures -- which is why I chopped the model up into pieces. But it works! And I wrote zero lines of code by hand. Back when I was running VC-backed companies, I would have needed a small team of grumpy greybeard engineers to do this and it would have taken 2-6 weeks. Now I can feed my own nerd fetish and do this stuff myself. Next up: I'm building an iPhone app that ties into your heart rate, movement data, location etc to generate a real-time soundtrack to you life. What a time to be alive! update: Demo video of it running on my iPhone 15 Pro: https://bit.ly/3RY7Gqh https://bit.ly/49OqDls June 10, 2026 at 11:22PM

Show HN: Ustps (UDP Speedy Transmission Protocol Secure) and USSH https://bit.ly/49JTG9F

Show HN: Ustps (UDP Speedy Transmission Protocol Secure) and USSH Hi HN, Over the last few days I've been building USTPS (UDP Speedy Transmission Protocol Secure), an experimental encrypted transport protocol built on top of UDP. The primary goal of USTPS is low-latency video streaming. A server can take a video source and expose it through a USTPS endpoint, while Linux and Android (Termux) clients receive the stream and expose it locally to applications such as VLC, mpv, and FFmpeg. Although streaming is the main focus, USTPS is not limited to media delivery. It can also be used for other reliable encrypted UDP-based applications, which is why I built USSH on top of it. Some of the main design differences compared to TCP-based transports are: - USTPS is reliable but unordered. - If packet N is lost, later packets can still be accepted and processed immediately. - Missing packets are recovered through selective retransmission. - Ordering is handled by the application layer when needed. This means the transport layer itself does not introduce Head-of-Line Blocking. The tradeoff is that applications which require ordering must implement reordering themselves. I consider this a reasonable tradeoff because it avoids forcing every application to pay the cost of transport-level ordering. For media player compatibility, the default USTPS client creates a local TCP endpoint at 127.0.0.1:1238. The client maintains a small reordering buffer (350 ms by default) to give retransmissions time to arrive before forwarding data to the local TCP stream. This allows existing software such as VLC, mpv, and FFmpeg to work without modification. USTPS currently provides: - Reliable delivery using ACKs and selective retransmissions - X25519 key exchange - AEAD encryption (AES-GCM and ChaCha20-Poly1305) - Optional unordered live output mode - Stream position metadata - Multi-client support - Local TCP compatibility output - No congestion control (currently intentional) While developing USTPS, I also built USSH, an SSH-like remote shell running entirely over USTPS. USSH uses the same unordered transport underneath, but the client reconstructs and orders terminal data before presenting it to the user. This prevents terminal corruption while still allowing the transport layer itself to remain unordered. USSH includes: - Interactive terminal sessions - PTY support - Password authentication - Host key verification (TOFU) - End-to-end encrypted communication through USTPS I'm currently using USSH from my Android phone through Termux to manage my VPS. The project is very young (less than a week old) and is primarily experimental and educational. I'm interested in feedback from people working on transport protocols, streaming systems, SSH implementations, QUIC, SCTP, and networking software.

Show HN: NoSuggest – Watch YouTube without the recommendation algorithm https://bit.ly/4vCZ475

Show HN: NoSuggest – Watch YouTube without the recommendation algorithm NoSuggest is a quiet act of resistance against YouTube algorithms always trying to pull you into a loop of unlimited videos in turn into unlimited screen time. With unending side cards of videos, auto-play, what's next suggestions, YouTube shorts and notifications, users will be doom scrolling for many hours in a day. I faced the same problem. Acknowledging that, not all content in YouTube is bad. There are educational videos, genuine news contents without political bias which is very hard to find outside YouTube and many other good relaxing, entertainment stuff. NoSuggest lets you only follow the YouTube channels you like and removes all types of recommendation YouTube has. So you don't waste time on watching things which you never wanted to watch anyways. UI is very simple. You add your favourite channels in "Channels" tab and latest 5 videos per channel excluding shorts would appear in "Feed" tab. "Search" tab is to search for specific videos to watch and "Saved" tab is to bookmark any video you want to watch later. Intention of NoSuggest is to provide whatever is necessary to extract whats good from YouTube all inside NoSuggest and leave out bad parts. NoSuggest works in any devices. Install it as an app (PWA) in android and iPhone, or simply open in browser in laptops. No sign-in, no account creation or no card details. NoSuggest won't even ask your name. Total privacy for the users. Parents can add the channels and save some educational videos and lock it with the pin for kids mode. Kids won't be able access unwanted additive contents inside NoSuggest. Completely free, no string attached. Source available in Github through NoSuggest website. I would love genuine feedback. Thank you very much for your attention on this matter. https://bit.ly/43hVGCv June 3, 2026 at 10:14PM

Show HN: Documenting an Obscure Japanese Wii Game – and-Kensaku I have been using Claude for the past couple of days this week to document and modify the TR2 game file format for an obscure Japanese-exclusive Wii game called And-Kensaku, or 安藤ケンサク. And-Kensaku is a game related to Googling. There are a few game modes, but the most famous one asks you a question and gives you two answer options, and you win if you choose the most popular Google search. I have been able to do the following: 1. disable signature checks on the files, and 2. allow edits to the Phrases.tr2 file, making it possible to modify the content of the aforementioned game mode. I wanted to go on this little adventure because reverse-engineering file formats is an extremely difficult (at least for me) and time-consuming task, and I wondered how well Claude would do at it. Right now, not everything about this game is documented, but I would like to fully document it and maybe release an English patch. https://bit.ly/4foIhjb June 6, 2026 at 01:48AM

No Python. • Tested on M3 Pro 18G / M3 Ultra 512G / M4 Pro 48G. All work fine. • HTTP server exposes search to local agents like OpenClaw & Hermes − Indexing still feels slow even on the latest M3 Ultra, ranging from 10K tps to 300 tps depending on file type − Fans go crazy, high power draw while indexing − Search is near-instant. Multimodal relevance is sometimes arguable, but the idea is recall (the agentic LLM takes the results and refines for the final answer), so maybe that's fine https://bit.ly/4x8eFNv June 6, 2026 at 12:20AM

Show HN: I nerfed our coding agents on purpose https://bit.ly/4agEscl

Show HN: I nerfed our coding agents on purpose Tl;dr: I trained a classifier to route to the least expensive model and reasoning depth to complete the request. Coupling that with additional automated token efficiency techniques has yielded 3x usage for the same spend. For anyone interested in trying it themselves: https://bit.ly/4vwwAeT Various teammates and I switched over to Codex from Claude Code recently. We still bounce between the tools, but Codex’s speed and steerability coupled with performance gains were hard to ignore. One of the downsides was that the per token pricing kicked in way sooner. This is happening across the board, but we felt it in Codex more acutely. We’re a startup filled with people who work around the clock and are obsessed with building — naturally our daily bill alone was striking. Luckily we’re going after a big mission and speed matters significantly more than marginal token spend on the edges. Still, it got us thinking about how it was ludicrous that while our product has a side effect of decreasing token spend and speeding up agentic workflows by many orders of magnitude, we were using these top tier models for all types of internal coding tasks without any of those optimizations. The waste felt pretty ridiculous — the most glaring culprit was that we were seemingly using the max intelligence model on max reasoning for every task even when the task clearly didn’t require it. As a company who spends a lot of time on cached intelligence, it was also easy for us to see how there was plenty of other low hanging fruit as well. So, on a recent weekend, I quickly built a tool to optimize our usage. At its core is a very fast classifier that classifies your requests to the least intelligence required for the task and includes some nice token optimizations on top. The result is roughly the same quality for multiples lower token spend. But even more exciting for us, is that the properly bin packed intelligence and reasoning levels meant our speed also went up considerably. This wasn’t negligible. We’ve observed up to 3x savings and hours per day per person in saved time that we would have otherwise been waiting on tool turns and coding agent responses. For us, that means improved engineering velocity and significantly higher usage for the same spend. It also means more usage before getting throttled. As I told friends about this, they also wanted to start using it to maximize the usage they could get out of their coding agent plans. There are now engineers across many of the most cutting edge AI companies using this tool to optimize their token utilization in this way. Not just to save money, but to maximize output. Turns out that the best way to avoid getting nerfed by Claude is to intentionally nerf yourself selectively. We decided to release it for the rest of the builder community to use as well. You can now turn on Nerfguard for yourself and start getting more usage today. June 6, 2026 at 12:19AM

Show HN: I embedded 685M public texts in 32 minutes (on 8x A100, Rust, TensorRT) https://bit.ly/3Q8vzuu

Show HN: I embedded 685M public texts in 32 minutes (on 8x A100, Rust, TensorRT) Quick note on how it works and how I've done my batch embedding engine IgniteMS. The whole thing runs as one process using Rust, reading input, tokenizing, packing batches, keeping the queue full. TensorRT handles inference. Python is only as a wrapper. I built it this way because when you use more than couple of GPUs, the GPUs stop being the problem. CPU cannot feed them fast enough. One A100 can go through batches faster than Python can tokenize and feed, so the GPU just sits there idle waiting for work. Most of my time went into optimizing this. At 8 GPUs that was basically the entire challenge. On cost. I ran the big 2B messages job on a spot p4d instance (8x A100 40GB). After filtering and dedupping I got 685M raw texts. With my new engine the whole production run finishes in about half an hour. Previously I used on-demand for these jobs, now switched to spots. If AWS reclaims the box, I just rerun it. It's roughly $7 for half-an-hour run. And at least right now spots are easier to get than on-demand. Open warning: it's batch only and NVIDIA only. You can use it both as a docker image and native. I used some optimizations for my production run. With default settings you can expect to see ~250K msg/sec if you run the benchmark script on your p4d box. https://bit.ly/43cKXcq... v1.1.0 added TensorRT 11 and 60 models, 23 tested on 1x and 4x A100.

If you'd like to learn more, an independent interview was posted a couple of weeks ago [1], and the FAQ [2] has a lot of information as well. For the source code sharing, we've talked with lawyers and are inclined to no longer require the NDA/NCC for privacy reasons shared with us before (signing requires identification), but instead use a source-available permissive license that doesn't allow competition, like PolyForm Shield [3] (we do still have about 6 months before finalising a decision, here). This does come with a lot more risks for us (it's harder to track down if someone publishes the code or uses it against the license), but given we've already passed 100 monthly active accounts, we're feeling more confident it's an acceptable risk. The plan is to give logged in accounts (who are 12 months old or more) a way to download a ZIP of the current code base that's in the server.

Show HN: an AI that settles small couple arguments https://bit.ly/4vt1MvN

Show HN: an AI that settles small couple arguments Nisrine and I have been working in the same company for many years (she's Head of Product, I am CPTO) and we have done great things for our employer(s) all along. But we always wondered if we could launch our own app – after all, we know the process of it all, we just "never had the time". The idea started from a random conversation, after Nisrine told me a personal story about she had a stupid little fight with her partner, and after 3 or 4 back-and-forths on each side, she decided she was right. Of course, he decided HE was. But he was not sure, so he asked chatGPT... And lost :) We were making fun of him but then we thought, wait: everybody fights for stupid little things. It would be great if someone impartial, neutral, with no bias, could move the needle in one direction. Not render a verdict like in a Roman Forum but just shows you where (both of) you are right or wrong, and then makes the person who is more in the wrong apologise. Yeah, an AI :) Why apologise? One, because it's the best way to bring back peace to any relationship. Two, because it's hard to let go, put your ego on the side and accept that, "yeah, it's not worth fighting or sulking, sorry". And three... because it's so cool to see the other one bow and lose the argument :) Come on, don't pretend this is not thrilling to win an argument! So we built this app, called Piece (sounds like Peace, it's the peace of offering to bring back peace – the logo is an olive branch). The app comes with different tones: witty, theatrical, sarcastic and counsellor (if you want to go deeper in the analysis). The principle is very simple: you record yourself, your partner records their version, you get an analysis of each side's good and weak points, then a verdict. The app stores everything locally, no personal data shared anywhere (except the ephemeral transcript). And the two partners need to use one phone only: that brings them closer already. And from there, you can imagine all the features you want: dashboard with analytics (who has the biggest ego? how many times do you fight?), sharing on social media for "funny" humiliation, karma points, music generation of your fights etc. This app does not replace the couple therapy apps, of course. We are more malicious, this is more about a gamified experience for the day to day arguments. While building the app (Claude + Claude Design, app is in Flutter if you're interested), we were amazed by how many hilarious sentences the AI engine came up with. We were not expecting something that smart, to be honest, and that was what we liked about this side project: every test was a laugh! – ok, maybe not when Nisrine introduced regressions in the code: she argues that she did not but we asked Piece, and I won... We had good feedback from regular users so we recently decided to launch for a bigger public. The app is on the iOS and Android stores (look for "Piece, relationships"), works in English and French for now. Free to start, we'll surely implement credits when we grow our audience.

Show HN: DepsGuard – one command to harden NPM/pnpm/yarn/bun/uv configs https://bit.ly/3POC85x

Show HN: DepsGuard – one command to harden NPM/pnpm/yarn/bun/uv configs I kept seeing every npm/pnpm/yarn/bun/uv supply chain post end with the same advice (set a minimum release age, turn off install scripts), and while I know cooldowns are "controversial", they do work. But even if you convince people that they should set cooldowns, it seems many don't end up following through, not sure why, maybe because it means hand-editing five config files in five formats with five different time units, or perhaps the "it won't happen to me" syndrome (or "I'll do it later, it seems complicated" where it's actually very simple). So I created a tool that checks what you have set and fixes it for you. I looked for an existing one first and couldn't find it. It started as a small weekend project and turned into a small research project on the nuances of cooldowns across package managers. Not a proof of P vs NP, but a small convenience that can save you and your loved ones from the next supply chain attack. I've raised this in a couple of HN threads since ( https://bit.ly/4wXqIgl and https://bit.ly/4udvqUG ) but never actually did a Show HN for the tool itself. If you know how to edit your ~/.npmrc, which settings apply to npm vs pnpm, and which one wants minutes vs days vs seconds, you probably don't need this. But if you vibe code and just want a one click fix (or you have a PhD in CS from Stanford, ex-FAANG, started 3 YC companies, now work at Anthropic, and still just want a one click fix), read on. DepsGuard is a single Rust binary, no runtime deps, MIT. Run depsguard and it scans your user-level and repo-level configs, shows a table of what is and isn't set, you pick what to change, hit d for the diff, and apply. It writes a timestamped backup first and depsguard restore rolls it back. depsguard scan is read-only if you just want the report. The settings are the simple ones that work: min-release-age / minimumReleaseAge (npm, pnpm, yarn, bun, and uv all name it differently and use days vs minutes vs seconds, which is half of why doing this by hand is annoying), ignore-scripts, and on newer pnpm block-exotic-subdeps, trust-policy: no-downgrade, and strict-dep-builds. It also handles Renovate and Dependabot cooldowns. The whole thing is a bet on timing. The malicious @bitwarden/cli 2026.4.0 was up ~19 hours and got 334 installs. axios was pulled in ~3h, ua-parser-js in hours, node-ipc in days. A 7-day gate means your installer never resolves any of those, they're gone before the window even opens. It does nothing for the slow ones (event-stream sat 2+ months), and it's not SCA, it won't scan your existing lockfile for known CVEs, that's a different layer. Disclosure: I'm a co-founder and CTO at Arnica (a commercial appsec startup) and built this because putting the same recommendations on each blog post felt like yelling at the clouds. It's free and MIT, no account, no telemetry. I'm also not the only one who had the idea (didn't know at the time), cooldowns.dev does the cooldown part across more ecosystems with a shell helper and is worth a look. DepsGuard covers fewer ecosystems but adds the other settings and the diff/backup/restore flow. If you want to try it: cargo install depsguard, or brew/apt/winget/scoop, all in the README. https://bit.ly/4udvrrI (full settings table and FAQ at depsguard.com) Is this an overkill that could have been a shell script? Probably yes (but I wanted windows support, why not). Did it save someone from a supply chain attack? Also probably yes. Do I know personally someone that without it wouldn't have bothered changing their settings after repeatedly asking, but eventually did it when I gave them depsguard? Absolutely yes. https://bit.ly/4udvrrI June 1, 2026 at 05:58PM

Show HN: I made a Gemma 4 Mac app that names screenshots with local AI I made my first macOS utility app that ships with a bundled Gemma 4 model, specifically the Gemma E4B one. It made my app DMG have 5.3 GB in size, but I think it is a small size for the power that this free local model can provide. It runs fine on CPU, but can also run on Apple Silicon GPU, although I did not notice any performance improvements with GPU (tested on a M5 chip). I think these local lightweight and multimodal models will open multiple possibilities for new software tools where privacy is essential. https://bit.ly/3Qch88P May 31, 2026 at 02:40AM

Show HN: Helios – what plug-in solar could generate for any address in Britain Plug-in solar panels (no electrician needed) have just become legal in the UK and will go on sale soon. Helios estimates how much electricity a typical installation could generate at a given address and what that's worth against your tariff. It uses UK government LIDAR data to reflect the actual skyline, so it knows whether there's a building or a hill blocking the sun. Caveats: - Outside LIDAR coverage (most of Scotland and Wales) it falls back to a synthetic horizon (less accurate). - Trees and recent developments (post-2022 or so) may not be in the data, and some address placements could be off (geocoding via OSM). Feedback on the shading model especially welcome. https://bit.ly/4wXJaFN May 30, 2026 at 12:08PM

Show HN: An update to our long-turn FreeCiv experience https://bit.ly/4uEW0aq

Show HN: An update to our long-turn FreeCiv experience So we have had quiet the journey here. So 70 days ago (aka 73 turns ago) I posted on HN sharing our FreeCiv deployment ( https://bit.ly/4cVt7Ro ). FreeCiv is a great game, the clients is very buggy however. I'm using the GTK4 version, but a few others have opted for the QT variant. At some point, we might turn our focus to contributing to improving the client based on our experiences playing the game. We've since added a lot of little fun features: - The editor: you can write to the newspaper Editor and they /might/ publish what you write, quote you, or decide you're full of it and write an opinion piece slamming your reputation. The editor will also reach out to a few players, each turn, and ask for their input on current game matters. - The Intelligence Dashboard. People were forgetting what they were up to, so we added a dashboard showing the timeline of what happens per turn for your player. - beta the online map viewer: I wanted a way to view the map without loading the client, so we started working on a beta map viewer that is HTML based. - The Chronicle (The newspaper) has also grown a bit. Maybe too much? We'll see. The crossword is fun. Some other 'fun' things that happened: my brother in law stopped speaking to me because of in game banter that was taken way too seriously. My friends invaded my wifes territory, and well, she didn't like that either. I'm currently in the lead, but theres still a long way to go from 475BC. https://bit.ly/49TxYA0 May 28, 2026 at 01:24AM

Show HN: Open-Source AI Racing Harness https://bit.ly/3PQ7dFL

Show HN: Open-Source AI Racing Harness Hi I'm Dan from Elodin, making an open source real-time capable flight software simulation. For AI Grand Prix contestants, the wait for the Round 1 virtual qualifier simulation has been grueling. If you’re competing, check out our simulation harness to tide you over, built to match the published competition constraints and message format. It runs against real Betaflight, which we learned requires at least 1000 sensor samples per second to run real-time correctly. The competition warranted introducing a new feature to generate the camera sensor directly in the simulation loop. Typically people connect to Unreal or similar game engine to create a camera sensor, which works well but is very heavy. For the simple needs of this challenge, creating sample directly in the loop is very handy and easy to use. Happy to hear your feedback on this! While it's not fancy looking currently, it uses the Rust Bevy game engine, which should allow us to improve the visual fidelity quickly. We all should easily be able to shift our implementation to the published competition sim once it lands. Hope you enjoy and good luck! https://bit.ly/42WNl75 May 27, 2026 at 09:37PM

Show HN: Stumbleback – StumbleUpon for the bookmarks you've been hoarding https://bit.ly/4uuG4Y1

Show HN: Stumbleback – StumbleUpon for the bookmarks you've been hoarding Hi HN, I have about 2000+ bookmarks that I will never read. Probably you do too. I keep collecting new stuff to read, the list grows longer each day, but I barely get around to reading them, and the problem, as I realised, is more to do with the analysis paralysis on what to read. Sort of like how we spend so much time figuring out what movie to watch on Netflix. So I made a simple Chrome extension: it picks one bookmark at random, drops you on the page, and gives you two buttons on a floating toolbar - Stumble (next random one) or Done (mark read and move to the next random one). That's it. It takes away the burden of decision altogether, and it's sort of fun to engage with because of the variability (and novelty) of what it loads next, while still being within the universe of things I've been wanting to get to. Also, I've added daily goal and streaks to keep me motivated to get through the list and turn it into a daily habit. You can simply Right-click -> Add to Stumbleback for new saves, otherwise it just reads your existing Chrome bookmarks, or you can paste URLs as well, no separate database. It's free. Would love feedback from anyone who's tried to get through their reading list of things and failed. https://bit.ly/49WYB77 May 27, 2026 at 05:34AM

Show HN: Posthorn, self-hosted mail without the mail server https://bit.ly/3PKMVNS

Show HN: Posthorn, self-hosted mail without the mail server Introducing Posthorn, a self hosted email gateway. One docker container (or Go binary) between every self hosted app on your VPS and your transactional email provider. Set up Posthorn once, point your apps to it, done. I was trying to deploy Ghost on a DigitalOcean droplet and found that DO and many different VPS services have started to block the default SMTP ports to try to combat the various types of abuse they get. To actually configure my app, I had to hack together a Postfix relay. In another project, I had a static site which had a contact form, but my free Formspree account was occasionally hitting usage limits and I desperately wanted some of the anti-spam features they had gated behind their paid accounts so I put together a caddy module to catch HTTP POSTs and bounce them to my provider. I kept bumping into these same email issues. Many of the services I wanted to host (Gitea, Mastodon, Umami, Comentario) ran into the same limitations. This felt like a really common issue that had no good solution. Posthorn is what I built to solve this. It's a small Go binary (or 10 MB docker image) that sits between your self hosted apps and your transactional email provider of choice (shipping with support for Postmark, Resend, Mailgun, Amazon SES or an outbound SMTP relay). It also accepts POSTs from HTML forms to support static site needs while adding security layers such as honeypot fields, origin checks and IP rate limiting. There's also a JSON HTTP API that supports Bearer auth for backend scripts or cron jobs that just want a /send endpoint. I now use this personally in multiple scenarios and I've spent a lot of time beating this up and testing against what I can validate. I'd love to hear how this might be useful for you, what breaks and any feedback you might have. It's open source under Apache 2.0 and I'd love contributions. I'm planning to support and grow this for the long haul.

Show HN: SaveNeighbor – food delivery through your own personal network https://bit.ly/4wKc1xf

Show HN: SaveNeighbor – food delivery through your own personal network Hey everyone, the idea came to me when I got a food delivery from a woman who mentioned she had her children with her. I thought, I wish I could request her every time I get delivery, just for the feeling of knowing just who my tips are supporting. That was 4 years ago, being non-technical I didn't see myself getting it done. But thanks to Cursor and Chatgpt, SaveNeighbor is born. I know the model adds friction and the convenience is low until you build up a network, but that's kinda the point. Think of Ubers 'Wait and save', if you can be flexible you can save big on fees. And being able to choose who your money goes to is the biggest benefit in my opinion. Shoot me all your questions, I can't wait to hear your feedback. Thanks. https://bit.ly/42URlos May 25, 2026 at 02:09AM

Show HN: Geomatic – a command-driven geometry studio enabled with autodiff https://bit.ly/3RvO8Jw

Show HN: Geomatic – a command-driven geometry studio enabled with autodiff All commands have the format `output = \func inputs` or just `\function inputs`. Points and scalars are built on the fly. Eg `\line a b` to an empty canvas creates points `a` and `b`, and joins them with a line. One can use broadcasting semantics similar to NumPy and PyTorch in a visual setting (imagine creating a list of circles where one dim corresponds to radius and another to the center). One can also use backpropagation, run gradient descent or visualize vector fields. Almost everything is reactive so changing a variable updates all of the downstream geometry. It also allows anyone to write and load their own visualization, which can be broadcasted and differentiated through. https://bit.ly/4uu8lxQ May 25, 2026 at 09:25AM

Show HN: Twixt – transform one word into another in four moves https://bit.ly/4o59vhf

Show HN: Twixt – transform one word into another in four moves I made this game while working on a different project about teaching English spelling. I was reading about homophones and got struck by how much a homophone can transform the shape of a word, so I started experimenting with little games built on that. I added a few more transforms, anagrams, verb/tense changes, but the answers kept coming out too obvious. I couldn't distort the word enough to make it interesting. The breakthrough was compound pairs. Jumping from one word to another through their compound (sea → horse, via seahorse) really obscures the path and that's when it suddenly got fun and unpredictable. I've been sharing it with friends. I'm in the UK so mostly UK testers, fair warning that a couple of the homophones may lean British. They've been playing daily and seem hooked, so it felt worth posting here. It's one puzzle a day mainly so I actually have time to hand pick puzzles that have a satisfying path. Today's puzzle is on the easy side but they can get really tricky. The name is from 'betwixt', the whole game is about moving between two words. I did clock afterwards that there's a 60s board game with the same name, but they're pretty different things. https://bit.ly/4nRbEgm May 21, 2026 at 01:29PM
