Show HN: Surraura – audio on your Mac in a simulated environment (Helps my ADHD) https://bit.ly/46UQwxP

Show HN: Surraura – audio on your Mac in a simulated environment (Helps my ADHD) I built an app to help my late diagnosed ADHD - through sound. The app wraps whatever is playing on mac through device convolution (old radio, hifi system) - Room convolution (a bedroom, a forest) and adds ambience (rain, wind, waves) and Apples spatial processing - so it sounds like a real space. For me - hearing the sound in a space really helps more than just the dry sound, the spatial information and ambience lets me focus much more. At some point I thought- Maybe others will have the same effect? So I took the care and effort to make into a nice app with the option of downloading additional environments etc. https://bit.ly/4hq0rl5 Thank you for your time, would love to hear your thoughts.

Show HN: Don't Hit Send – the model answers while you type Type. The model is already answering. There is no send button. Left pane is one long draft. Right pane is a stack of replies. Pause for ~350ms and it fires a normal streaming chat completion with the whole draft. Type again and it aborts the last request if that reply never produced text; if it did, that bubble stays and a new one stacks. Bubbles never rewrite. Enter is a newline. That is overlapping unary streams, not a duplex socket. Same shape as ghost-text, pointed at a conversation instead of a code line.

Show HN: Dbmask – Discover, mask, and verify sensitive data in SQL databases https://bit.ly/4xh0vII

Show HN: Dbmask – Discover, mask, and verify sensitive data in SQL databases Hi HN I developed *dbmask*, an open-source Python tool designed to discover sensitive columns in SQL databases, masking them with deterministic fake values, and validate the masking results. The motivation behind this tool stems from a common issue I encountered when handling test data: existing masking tools often assume the user already knows exactly which columns contain sensitive information. Furthermore, the successful completion of a masking task does not guarantee that all sensitive values have actually been replaced. dbmask aims to integrate these steps into a unified workflow rather than treating them as three separate tasks. During the detection phase, the tool makes determinations by combining column names, sampled values, database type/context, historical decisions, and optionally LLMs. While LLM functionality is disabled by default, it supports local execution via Ollama or other services compatible with the OpenAI API. If the tool cannot determine a column's nature with confidence, it marks it as `UNKNOWN` rather than simply classifying uncertain cases as "non-sensitive." I also wanted to incorporate human decision-making into the system. Detection results can be exported for manual review, and confirmed decisions can be saved in CSV, XLSX, or Markdown formats, or stored in a SQL history decision table. The system logs information about both the analyst and the reviewer and re-evaluates past decisions if column types change or review results expire. The masking process employs deterministic mapping, ensuring that identical original values consistently map to the same synthetic values across different tables. Once masking is complete, the `dbmask validate --strict` command compares the masked copy with the original data, checking row counts and table structures, and verifying sensitive values row-by-row using primary keys wherever possible. The project is currently in its early stages (version 0.1.x). The current CI (Continuous Integration) pipeline covers SQLite testing; integration tests for PostgreSQL and MySQL, as well as public detection benchmarks, are included in the future development roadmap. I would particularly appreciate feedback on the detection rules, the manual review/history tracking workflows, and the verification methods. Please let me know if you encounter any usability issues or potential security risks while testing on the temporary database. Install: pip install dbmask https://bit.ly/3Vnsmtg September 10, 2026 at 04:15PM

Show HN: VolAnti – Open-source acoustic detector for fibre-optic FPV drones https://bit.ly/4cugcVu

Show HN: VolAnti – Open-source acoustic detector for fibre-optic FPV drones This project has been a month in the making, and 9 fully functional units will be sent tomorrow to an undisclosed civilian site across the Israel - Lebanon border. All of my findings are shared online to anyone on the globe who could benefit from them, or make their own units. I'm an engineering student at the University of York, originally from Israel, studying in England. I too often have been hearing about tragic cases involving civilians in war zones being chased and attacked by small FPV drones mounted with an explosive. Especially around the north of Israel, Ukraine and Russian. My intentions for this project were clear: create a device small, portable and cheap enough for civilian use, that could drastically change the outcome of a drone infiltration through early alerting. I decided to dedicate a month of my summer to go back to the university labs and to work on this as personal project. These drone attacks are not run on normal wireless drones, instead they are run on small FPV drones that are connected to the operator through a long spool of fibre optic cable. This simply means that drone detection through Radio, the current industry standard, is not applicable. My solution was to build an acoustic detector. A device that uses 4 MEMS microphones to capture the drone's propellers' emitted noise as they cut through the air, runs that data through several algorithms to enhance the SNR, reduce noise (directional, possible confusers), recognises their comb looking shape when plotted by frequency, and alert the user through multiple outputs (display, beeper, buzzer, led) along with alerting all nearby units using a LoRa module also fitted in the device. The units have been tested against a custom drone rig, housing the exact same specs as the drones used in the Israel-Lebanon border (four 2807 motors, 7 in tri blades, FPV airframe), which was stationed 104.2m away from the device in a street with passer-by's and mild wind. That test ran successfully and the device was able to detect the drone. This device was built for detection and alerting only, so no jamming. Every online resource i could think of in regarding this project exists in the Github, along with a neat website that shows off more media with explanations, also housing a live detector simulation that runs in the browser: https://bit.ly/4xQf1IC https://bit.ly/4gVfWQq September 9, 2026 at 01:08AM

Show HN: Zero downtime embedding model upgrades https://bit.ly/4ctEEq2

Show HN: Zero downtime embedding model upgrades People use embedding models all the time for rag/semantic retrieval. However, when a newer, more desireable model comes out, there is an expensive (both in time and computational) cost of re-embedding every document in the database. However, I figured out an interesting way to forgo that upfront embedding cost. algo: old model/index -> retrieve top-K docs -> score those docs with the new model -> cache/materialize the new embeddings so instead of rebuilding the entire vector store upfront, the old index keeps getting retrieved from, while the new model reranks those candidates. This works surprisingly well for some model pairs, (i tested 63 source-> target migrations on h100s, on upto 1M documents). For example, on a 1M document Natural Questions dataset, native Qwen3-Embedding-8B: 0.6812 nDCG@10 Qwen3-4B -> Qwen3-8B, K=50: 0.6816 Qwen3-0.6B -> Qwen3-8B, K=50: 0.6638 MiniLM -> Qwen3-8B, K=50: 0.6486 (the hard part is determining k, I held the k constant above to give some sense of migratability). You can install it with pip pip install embedflow and the code is on github https://bit.ly/4zXvTyx https://bit.ly/4zXvTyx September 8, 2026 at 03:35AM

Show HN: TimerVana a Local-first scheduler for real world routines https://bit.ly/4cNMJ9d

Show HN: TimerVana a Local-first scheduler for real world routines Hi HN, I’m the creator of TimerVana. It's not just "another timer app". The engineering analogy is a lightweight task scheduler for things people do in the real world. A normal timer models one countdown. TimerVana models a small dependency graph in JSON: some steps run sequentially, others run in parallel, and everything can converge on a target finish time. You can also combine multiple timers (e.g., combine a timer with all the steps to cook a steak + a timer for roasting vegetables). I originally built it because I often set multiple timers and alarms when cooking and got tired of repeatedly juggling separate alarms to get a main dish and several sides ready together. The same model also works for workouts, study sessions, morning routines, and other repeatable processes. The iPhone app is local-first by design [0]. You can create, save, and run timers entirely on your phone without an account or cloud sharing. If you want the networked features, the companion website lets you browse and download timers, upload your own, and share them with other people. Everything available today is free. I may eventually add optional AI-assisted timer creation as a paid feature, but I haven’t settled on the business model or pricing. I'm more doing this to solve my own problem and hope it will help others as well. I’m interested in whether the underlying abstraction makes sense: does a sequence of dependent and parallel timed steps help you? I’d also appreciate feedback on the balance I took between the completely local experience and the optional sharing layer (I was partially inspired by the old iOS Workflow App, which was acquired by Apple and is now called Shortcuts). Of course, any other feedback very much appreciated. [0]: https://apple.co/4zXnb3g... https://bit.ly/4xcAWbQ September 4, 2026 at 11:47PM

Show HN: Reactor Atlas https://bit.ly/3Vc6aSN

Show HN: Reactor Atlas Hi HN, I'm a nuclear engineer and tech entrepreneur. After working for 3 years in the National Atomic Energy Commision (CNEA) in HPC software for nuclear simulations, I co-founded ratherlabs.com, a software company providing blockchain solutions for startups. Rather Labs business reached ~6 million usd in annual revenue in 2024; now demand is decreasing as our niche clients are using AI to launch their MVPs. Now I'm joining my scientific background with my entrepreneurial inclinations to think of problems related to the energy industry. Nuclear is experiencing a renaissance now (it was in a dark age when I was studying after the Fukushima event) so I think this is the right moment for me to jump again into the field. Reactor atlas is an interactive nuclear reactor map and an intelligence layer on top of it. The basic layer indexes: - power reactors - research reactors - fuel facilities with their history and projection, by country. The project is solving a fragmented information ecosystem, where operational and commercial data is hard to conciliate. Also, I'm monitoring nuclear news associated with each of the facilities, political declarations that may affect the nuclear landscape and geo-phisical news (like earthquakes) that could affect operation. On top of the operational + news layer, I'm creating an intelligence layer that will help institutions of different types make faster decisions by subscribing to very specific alerts. As an engineer, I used to code in fortran and c++ when I was working at CNEA, and later I participated in the first Rather Labs projects architecting complex async systems, mostly using MERN stack. I'm no longer coding anymore. I'm focused on designing robust systems with AI agents. I mainly used Claude Fable 5.1 to develop reactoratlas.com, deploying on vercel and using mostly nextjs, threejs, postgreSQL and some cron jobs to query and update data. I miss coding as in the old days, but I haven't code a single line in this project. And I strongly believe we humans shouldn't code anymore: our responsibility is now on designing and supervising AI systems. Thanks for your attention! https://bit.ly/3US1Vf6 September 3, 2026 at 01:33PM

Show HN: I made a word building game supporting anagrams and one handed use Hi everyone, Wanted to share a game I built. It's called Unscramble! and I believe it's the simplest word building game. Rules: You get a few letters on screen. You need to make one word with all the letters. Tap a letter to select. Tap again to deselect. Faster you go, better you score. If you enter anagrams of the word it's looking for, it gives you extra points. If you are stuck, you can either "Ask Friend" or get Hint. You get extra points for getting the word fast but you don't get penalized for taking too long. I believe the simplicity of the game along with big touch buttons makes it perfect for one handed use. There's 6 difficulty levels in the game, and settings for things like toggling the timer, relaxing background music, sound effects, haptic feedback, removing the background animation. If you want to try: https://apple.co/4yiPgQP... Would love to hear feedback to improve it. September 3, 2026 at 03:37PM

Show HN: Saccade – Live semantic browser truth for AI agents I build one this application is to resolve the most of the agent cannot handle the brother they extremely slow. So I come up with this idea, we install one of the extntion on chrome or edge to give continuously compile the tabs authorized by the user into semantically meaningful objects with stable identities, and push page changes as deltas to the local Node.js Broker. The Agent reads the full truth or delta of the specified tab via MCP and executes actions using object IDs bound to document. The preliminary result shows that it is very close to the performance of Playwright in terms of token use and speed. The only problem with this one is that at the very first time, it is going to send the full truth, and after that, for any page changes, it only sends the data. So, after the first read, the continuous operation of the page reaches the millisecond reaction loop. It can also upload filled forms, downloads, and all kinds of stuff. I want somebody to check and use it. If it is possible plz give me some feedback. https://bit.ly/4qPDIC8 September 1, 2026 at 12:35AM

Show HN: Use-Fs – A React Hook for the File System Access API and OPFS https://bit.ly/4ivPTBP

Show HN: Use-Fs – A React Hook for the File System Access API and OPFS I'm happy to say that https://bit.ly/4qCcgrr 2.0 has been released with brand new OPFS support. If you're building browser-based apps that heavily interact with the file-system this package is a must to have in your package.json! A React hook that watches a directory and re-renders when a file is added, changed, or deleted. Point it at a folder the user picked and you're reading and writing their real files — no uploads, no endless file dialogs New in 2.0: it watches the origin private file system too. No picker, no permission prompt, no user gesture — and, unlike File System API, it works in Safari and Firefox What's OPFS? A file store the browser gives each origin — real directories and files, but readable only by your own site through the File System API, never by the user's file manager or other apps. https://bit.ly/4qCcgrr August 25, 2026 at 11:58PM

Show HN: Ecdeos – P2P Web/Native Distributed OS on Entity Core Protocol https://bit.ly/4qIzfkQ

Show HN: Ecdeos – P2P Web/Native Distributed OS on Entity Core Protocol Hello, I wanted to share an update of the current progress of the Entity System. https://bit.ly/4geUCXe is one domain in a constellation of peers/sites that is the main project of the Entity System, a Tauri Rust/WASM browser engine and Rust backend built on the Entity Core Protocol. It's primarily a research prototype of a P2P distributed cross-platform userspace operating system. The long-term goal is functional P2P management of devices and applications, scaling from individual use (managing personal devices, apps and servers) to multi-user organizations with internal services/application stacks all the way to internet-scale public or federated P2P networks. Its closest parallels are Plan9, Erlang/BEAM, IPFS, ATProto, Nostr, as well as many other antecedent technologies including Git, HTTP, and other internet protocols. The particular combination of features and focus on "everything is an entity", content-addressed data, full decentralization, and its capability security model gives it a unique position in the landscape, most of it coming from the Entity Core Protocol itself. Each web deployment also ships with 30+ Entity-Apps including games, music (forgive me if the audio misbehaves, it's fully synthesized running on the main thread), art and basic tools. Entity-Apps have a basic contract with the host and run in isolated iframe sandboxes; they're currently written in Javascript using a custom engine. Also included are a few Entity-Native compute apps running as Rust WASM Entity Core peers in an iframe that show the transferable Entity System compute language running live on a cross platform generic system host interface the engine manages. The compute code is compiled/tested on a separate workbench Go project which operates a parallel implementation of the application conventions, generic system host interface and the Entity Core Protocol. The Tauri native backend peer includes support for SQLite storage, TCP and WebSockets, while the browser environment supports WebSockets and WebRTC P2P chat, file and entity transfer - with plans to add more storage, networking and application conventions. Sites and a registry example are hosted at https://bit.ly/4gSgmbB . All the Ecdeos-based domains are running with peers in "coral reef" mode (no live peer required) and can pull the CDN hosted registry names and fetch the signed hosted sites from any other domain/peer in the network; they are cached locally in each peer's local storage afterwards. Peers can sign/host their data publicly on standard commodity hosting services and both the registry and sites are available to any application that understands the Entity Core Protocol and system extension standards. For the other example domains with peers hosted on static sites as well as more background information, see https://bit.ly/4gTdF9G , https://bit.ly/4d3pY0O , or https://bit.ly/4y5IVs3 . Bills Lab is the research arm that is currently exploring the background technology from different perspectives. Almost all of the code and content is AI generated, but we do our best to make it some of the best slop available on the internet. The overall project is still early and needs to get stress tested but the design is holding up well so far. Let me know if you have any feedback. -Bill https://bit.ly/4geUCXe August 25, 2026 at 10:20PM

Show HN: I wrote a BASIC interpreter that boots on UEFI machines https://bit.ly/4itDGxv

Show HN: I wrote a BASIC interpreter that boots on UEFI machines I started writing Thoreau BASIC because I wanted a small, old-fashioned BASIC interpreter: line numbers, immediate mode, simple graphics, strings, arrays, the sort of environment where the computer starts with a "Ready" prompt and you can immediately make it do something. Then I wondered: why should it need an operating system? So I made it boot directly on x64 machines using UEFI. The UEFI version uses the Graphics Output Protocol for its framebuffer and gets its keyboard input directly from the firmware. There is no Windows or Linux underneath it. The machine boots into BASIC. It supports the usual BASIC machinery plus graphics primitives, 32-bit colour, floating point, file operations and other features I've been adding as I encounter programs that need them. There is now also a Windows version, which makes it considerably easier to try. One of my goals is compatibility with the style and behaviour of old Microsoft BASICs rather than creating a modern language that merely happens to use BASIC syntax. I'm currently porting my text adventure Pixel Prose to Thoreau BASIC. That's becoming a much better test suite than artificial tests because every missing feature or subtly wrong behaviour eventually gets exposed by an actual program. The project is deliberately small. The UEFI version greets you with: "I make myself rich by making my wants few." — Henry David Thoreau followed, somewhat ironically on a modern PC, by something like: 27,340,685,312 bytes free I'd be interested in hearing from people who wrote BASIC in the 80s/90s, interpreter/compiler people, and anyone sufficiently strange to still find a Ready prompt inviting. https://bit.ly/4it2t4R August 23, 2026 at 06:48PM

Show HN: Vidmoat – My Super Fantastic AI Native Video Editor (MCP, Web) Hi there, I'm working on Vidmoat. A couple of months ago I wanted to venture into making videos. The only issue was that I suck at editing them. No amount of YouTube could hide the fact. But here's what I don't suck at. Building new stuff. I've also marveled at so much product demo videos and never quite figured out how to make my own (or pay for a professional to make one). So I made Vidmoat, my own personal AI native editor which provides an interface AI can drive. Works for both professionals and non-professionals. I mostly use mine via Claude MCP to handle edits for me and make entirely new clips. The exciting thing is that it's not limited to the provided tools. I built a 3d plugin so allow me animate a mascot i was building in 3D. I'd appreciate and love any feedback I can get on this https://bit.ly/3SQaera August 23, 2026 at 10:56PM

Show HN: CtrlTool – 132 free online tools for developers and everyday tasks https://bit.ly/3UaDSrz

Show HN: CtrlTool – 132 free online tools for developers and everyday tasks Hey HN, I built CtrlTool because I kept needing small tools for random things and didn't want to install something or sign up for another website. It currently has 132 tools for things like JSON, JWT, Base64, URLs, text, hashes, PDFs, SEO, converters, generators, and other everyday stuff. The main thing I tried to focus on is making the tools fast and simple. For tools where it makes sense, everything runs locally in the browser so the data doesn't need to be uploaded to a server. It's still very new, so I'm mostly looking for feedback on the UX, which tools are actually useful, and what you think is missing. https://bit.ly/4gJaKAp Would appreciate any feedback. https://bit.ly/4gJaKAp August 23, 2026 at 02:44AM

Show HN: OzBrain, a shared brain for knowledge between agents and your team https://bit.ly/3ULYK8E

Show HN: OzBrain, a shared brain for knowledge between agents and your team I think agent-first chat interfaces will be a primary software modality and busy dashboard/UI will go away. I’m not sure who exactly wins it, but I want my knowledge to grow/go with me. A lot of the “knowledge” ie research, analysis, reasoning will be done by agents as the primary user. Our current notes tools & tasks management systems were built for humans… I don’t care what the 17th thing on my bug backlog is. I want to conduct agents that can execute for me and do great work. What I built OzBrain to do: + Create a central place for agent reasoned knowledge to live + Be agnostic about what apps/agents connect to it + Capture everything and track it so I can audit it + Enable teams, collaborators or partners to share brains + Handle conflicts so many agents in the same article doesn’t blow up + Refactor knowledge into more token friendly chunks and map the index well + Close the knowledge loop so new thinking supersedes old thinking across the corpus. Don’t erase, depreciate and link + Keep user data safe and secure ++ Be easy enough to use that you don’t have to have any technical knowledge Some among us will always build their own custom solutions, but there are millions of tech professionals and small business owners that will use agents heavily and need a solution. So I’m trying to build that. Isn’t this like gBrain? Yes, similar. I think it’s like AWS vs Vercel. AWS is very powerful, configurable, and useful if you’re technical and want to invest the time into really fine tuning your system… but if you just want your web deploy/hosting to just work and be easy to deal with you use Vercel. // WHY I MADE IT I’ve been enjoying getting back to my technical roots, as I lost my coding skills more than a decade ago, but with AI I can focus on the system and the product in partnership with agent coding workflows. I recently built a Voice AI for older people. To build it I created an agentic engineering workflow (feel free to rip that up as I’m always looking to improve systems: https://bit.ly/3UsGC3y ) My approach with coding agents is trust but verify, and I’m trying to replace the parts where a human would review with an adversarial or specialized agent who would give a better answer/review. I have workflows that will go high level task to shipped PR running in Claude cloud sessions. I use Claude Code locally and Cursor when I want a tighter loop on doing visual work like UI or layout. And Codex to either load balance usage for TokenThriffting or when I want a different llm to think thru something. It was a pain in the ass passing .md files around and keep track of which version was the most recent, so I built a hosted .md storage right in Supabase and any of my agents already have Supabase access. This let me build a solid, scalable, secure voice AI from my phone at the gym. All my agents have access to our knowledge, can write to it, update and refer to it as we build and improve the product and the systems we use. Out of 75 founder friends I asked about how they manage shared knowledge, 26 built their own custom knowledge systems… Obsidian vaults with 7k files synced through a VPS, markdown repos behind their own MCP servers, cron jobs stitching Supabase to a skills file… each a different Frankenstein they have to maintain. 32 said they felt the pain of moving static files around but didn’t have any solution for it. So I rebuilt my brain better and used it to build it. // HOW YOU CAN HELP Would love to have you try it out. The maintenance loop is still in alpha so not running it on customer data yet. If you built your own brain I’d love to hear how you did it. What criteria was most important for you in its design & function. If you are tired of shuffling .md files around I’d love to have you try out OzBrain and to give feedback, just ask your agent to put it in the shared bugs & features brain! Cheers!

Show HN: Linux and iPhone Continuity (iMessage / SMS) After switching to 100% Linux a couple of years ago there was basically only one thing I missed about macOS and that was what Apple calls "Continuity". It's where you get texts, notifications, clipboard sync, file transfer (to/from) the iPhone from the Mac desktop. Especially that thing where OTP codes via text autofilled into the browser form I was waiting on. It took about 4 months of work: - reverse-engineering Apple/iOS Bluetooth behavior - MAP / OBEX - Bluetooth LE + Wi-Fi working together - iMessage through the iPhone's own cellular/iMessage stack - iOS app, Linux daemon, GTK app, Thunderbird/Firefox extension - no Mac involved But it is now something I'd love to show people.

Show HN: Mail client optimized for self-hosted email across multiple domains As someone with a clean IP range and ADHD, I manage my inbox by splitting across a variety of accounts for a variety of domains. I’ve never really found a client that scratches all my itches, so I spent some time making one and it’s now become my daily driver. It’s optimised to be visually simple and highly configurable for things like colour, folders/subfolders, sorting and tweaking the search query function to better match what you search for often. There’s also some little nice-to-haves like a purpose-built PWA, bulk domain onboarding, MCP and dark mode. It’s fully self-hostable, open source and free of any AI bloat/VC fodder.

Show HN: A new way to read books, magnifying in and out https://bit.ly/4quXtyL

Show HN: A new way to read books, magnifying in and out After watching The Odyssey, I thought it would be cool to check out some scenes from the source in detail, but I don't have time to read the whole book. So I came up with a sort of zoom/microscope, that allows to see the whole book at a glance and then zoom in (by pinching) on the part I'm interested in. I can do so down to the actual source text and get the authentic feel the author intended, at the same time I better understand where am I in the text and also the character and places are clickable so I can quickly orient myself on the context. Moreover each character has relationships listed and a map of relationships can be opened from there https://bit.ly/4qthZzF https://bit.ly/4qtw1Bq August 19, 2026 at 11:21PM

Show HN: Draw.city – geography game where you circle the target population [US] https://bit.ly/4gfdV1d

Show HN: Draw.city – geography game where you circle the target population [US] The core idea is, you draw a circle on a satellite view map and it tells you the population inside + more info. The home page is a daily challenge, I've backfilled some "past challenges" so there's more than just the past couple of days to play, and there is also a free-draw mode that tells you population + some census demographic info & points-of-interest data from OpenStreetMap. In most cases, the data comes from taking the census blocks w/ centroids contained in your circle and summing their population. Demographic info is slightly more complex as it's not sourced on blocks, so we allocate population-weighted fractions of a source territory's published census values into the drawn territory. Happy to answer any questions about the data or the technical side. The game/app only covers US areas at the moment, I'd like to add international data in the future!

Along with political arguments that have been litigated to death, people's issues with smooth scrolling on blogs, etc. Many of these comments do not get flagged for whatever reason. So I made a service to automatically classify whether comments violate (a modified form of) the HN guidelines automatically. In addition there's a Chrome extension to collapse these comments (if they violate your score thresholds) so you don't have to read them too. You can also just watch guideline violating comments as they are posted on the home page. Here's more info on how it works: https://bit.ly/4ifpatb https://bit.ly/4zpdGtk August 17, 2026 at 05:04PM

Show HN: PageSieve, a web scraping browser extension https://bit.ly/45rF6B8

Show HN: PageSieve, a web scraping browser extension PageSieve[1] is a browser extension for scraping data from different websites from within your browser. Currently it's Firefox only but I am open to porting it to other browsers if that's something people want. My original motivation for this started with a desire to improve the capabilities of the selectorgadget[2] bookmarklet to support extracting as well as finding selectors. The ideal use case is when some data you need is useful but you don't want to spend the effort of writing a one-off script to extract it especially nowadays when a lot of websites need an entire JavaScript environment to load correctly which complicates scraping. Using this extension means you only need to maintain the selectors for extracting the data and don't need to worry about managing dependencies. As long as the website can be opened in your browser you should be able to scrape data from it using the extension. I have a lot of features planned as well as some rough edges that need smoothing. I use this extension nearly everyday and I hope it can make somebody else's work easier. Take a look and let me know what you think.

Show HN: Mocktail – Free, open-source mock API server with a built-in dashboard Hi HN, I built the first version of Mocktail years ago. I recently came back to the project, and after a pretty substantial rebuild, v4 is now out. Mocktail is a free and open-source, self-hosted mock API server with a built-in dashboard and database, packaged as a single ~25 MB binary. You can run it locally or on your own infrastructure — no account or hosted service required. You can define endpoints and responses, generate realistic data per request, customize headers, status codes and latency, and inspect incoming requests in real time. With v4, I also added MCP support, so coding agents can create and manage mocks directly, along with an optional built-in AI assistant using your own API key. Both are completely optional. It’s been fun coming back to something I built years ago and bringing it up to date. I’d love to hear what you think, especially anything you’d change or add. https://bit.ly/4ws1Iwg August 14, 2026 at 09:20PM

Show HN: Woxi - Open-source Mathematica / Wolfram Language reimplementation https://bit.ly/45iHz0H

Show HN: Woxi - Open-source Mathematica / Wolfram Language reimplementation Woxi is an interpreter for the Wolfram Language written in Rust. It comes with Woxi Studio, a Mathematica-like GUI built with iced, but you can also use Woxi through a CLI, Jupyter kernel, Python package, npm package, or WASM module. Compared with wolframscript / Mathematica, the main differences are: - Free and open source - Very fast startup - Typically milliseconds rather than seconds for the Wolfram kernel, making Woxi practical for shell scripts, one-liners, and other short-lived processes - Embeddable - It can run in a browser via WASM or be embedded into another application as a scripting language A more detailed comparison with Mathematica is available here: https://bit.ly/45jDf1h . Conformance is ensured with ~26'000 unit tests and ~900 .wls script snapshot tests. The current focus is on fixing remaining edge cases, improving performance, and growing the community. If you use the Wolfram Language, I'd be particularly interested in feedback on compatibility and missing functionality. Contributions and bug reports are also very welcome: https://bit.ly/4m3tg7n https://bit.ly/3StnUrW August 12, 2026 at 11:06AM

Show HN: Albedo – single-file listenable document database in Zig https://bit.ly/45lGaGC

Show HN: Albedo – single-file listenable document database in Zig It's literally an indexable BSON array with query listening, replication and basic crash recovery. While working on my little projects I always felt a need for some sort of simple storage, where I can just have a single file. However sqlite with its' schemas and migrations always felt icky, like an overkill to have a single file db, but a whole folder set for migrations. JSON files would require to be loaded all at once and for something small but thick, like microservices that would hold their own state this would be a startup time cost. So idea came initially as an "indexable and partially loadable json object array". From the very beginning I've wrote it in zig, unlike my other projects where I flip flop with implementation language, for the sole reason that I wanted to be able to use it in as many places as physically possible. So it was something on level of C\C++, Rust and Zig. C langs are awesome, but I genuinely didn't enjoy them. After initial tries Rust felt overbearing, so by method of exclusion I landed on the lizard lang. I've been working on it for about a year, all while learning zig, relearning working with memory and adding new features. This whole time I've been mainly comparing it to and learning so much from sqlite, and eventually, after tuning, I feel like the performance is close enough for me (at least in my very basic benchmarks on my laptop). Now it's my personal little engine I use in my mobile apps through flutter plugin, in my small backends using bun ffi \ node native modules. Would be cool if it would solve someone's else pains.

Show HN: CityEdit – Open-source map for voting on NYC street changes https://bit.ly/4bxZwvP

Show HN: CityEdit – Open-source map for voting on NYC street changes CityEdit (cityedit.org, https://bit.ly/4wf791E ) is a map where anyone can propose street changes, e.g. safer crossings, new bike lanes, improved tree beds. Neighbors can then vote on those proposals. We just soft launched the app by hanging posters with QR codes at NYC's statistically most dangerous intersections (from open crash data at https://bit.ly/4yZIccT... ). Read more at https://bit.ly/4wufqit... (A poster turns out to be a great distribution channel - it reaches exactly the people who use that street, when they are using it!) The ultimate lofty vision is to build a sensorimotor loop that can awaken a city's collective consciousness: the community perceives its desires, proposes, votes, acts. Two disclaimers: 1. A vote on a map is more of a signal than a mandate, and may be unlikely to inspire government action. Instead, for now, we are going to enact what changes we can through some cheeky tactical urbanism. ( https://bit.ly/45K5dTQ ) 2. There is selection and presentation bias inherent to how we've built this. Our aim is to be as transparent as possible about who is participating, and who is missing, rather than faking general consensus. We're also seeding maps with existing commute data to fill in gaps wherever we can (e.g. Citibike trip data on the NYC Bikes map) Critiques are welcome, especially skeptical takes on whether this type of civic feedback loop can work. But please be constructive too! https://bit.ly/4wK61Eh August 6, 2026 at 12:58AM

Show HN: Humor Arena – Which frontier model is funniest? What if you could measure humor? Well we've trained a model on our own dataset of ~50k human ratings to detect what jokes people find funniest. We know it's part objective, part subjective component. Subjective is out of our depth for now haha The main results: Fable 5 is funniest - beating the average model 67% of the time, with GPT 4o last at 17%. Other findings: - The models never refused to try, even with dark prompts - Thinking longer has a slight benefit - Absurdness correlates negatively with joke quality Some methodology notes: - We benchmarked our model against the human majority and it agreed 72% of the time in a blind sample test. - We had 51 US adults rate the jokes, each blind to the models, with joke order randomized, and quality checked for attention and speed. - To rate some yourself visit https://bit.ly/45GoLbJ The full benchmark here: https://bit.ly/4fHqzHw Am taking requests if there's more research you want to see!

Show HN: I built a free Open Graph image designer I'm working in e-commerce for more than 15 years, and the OG images are still one of the mos neglected parts of a shop. On a few projects, even fairly simple product specific image improved the conversion from shared traffic, which is what originally led me to work on this problem. The new free tool is a browser based Open Graph image designer. You can choose a template, customize the content, add an image and download the OG image. It works without an account and manually uploaded images stay in the browser. There is also an optional checker for people who do not want to start from scratch. It can inspect your page and create an initial image proposal from its content, which you can then open and adjust in the designer. I would appreciate feedback on the templates and any customization options that feel missing and of course improvements. Thanks. https://bit.ly/4fNam26 August 1, 2026 at 11:30PM

Show HN: SmokeVPN – All-in-One WireGuard VPN Hub – Switch Exits in Realtime https://bit.ly/4hIq7dh

Show HN: SmokeVPN – All-in-One WireGuard VPN Hub – Switch Exits in Realtime I have started developing a prototype of a WireGuard VPN hub, where I could set a custom exit to a specific device, for example, my TV box would use a VPN in Germany, while my desktop a VPN is Serbia and I could switch the exit in realtime without having to stop the VPN connections and consequently no disconnections (ssh, etc). The project grew, and I ended up adding SOCKS5 and HTTP proxy, Tor exits, exit pools, random exits, timed exits, and exits/routes based on domains or IP addresses. I also added an in-house DNS with several default block lists (malware, gambling, social media, etc.) I found this project to have potential and decided to commercialize it, Smoke VPN was born. The logs live entirely on the RAM, and I plan to open-source the full stack as soon as I get feedback from real users, people like you... Can you please try the project for free for 7 days or 50 GB (whichever comes first)? You don't need an account, email or password and you can add up to 10 devices.

Show HN: Replicant Space – an HTTP API-based game based on the Bobiverse books During Christmas 2025, I found myself burnt out from work. The last few years had been hard, and multiple redundancies saw the company I loved reduce down to just a handful of remaining staff. As a coping mechanism, I kinda disassociated for a while - throwing myself into my personal projects. AI was destroying the passion I had for coding. I tried to find some meaning in development again. After months of throwing myself into creating this game, I slowly fell back in love with coding. I taught myself a bunch of technologies that I was previously unfamiliar - Astro, Flask, Redis, Celery, Just. Anyway, this is Replicant Space. It's free. I love building and playing it.

Show HN: GG Translator – Turn gaming shit talk into friendly phrases https://bit.ly/45abJDn

Show HN: GG Translator – Turn gaming shit talk into friendly phrases Flaming teammates usually results in them cooperating even less. But sometimes you just need to let the devil out of you. Instead of venting on your teammates and pissing them off, vent into GG Translator and it will convert your toxic message into a friendly and constructive one to share with your team. https://bit.ly/4wsxdqW My background is in building web apps with Elixir and Phoenix. I made GG Translator in early 2024 to see if I could build a desktop app in a language I had never used before (Rust) with the help of AI. It was a great exercise and I found out that I could. I used Tauri instead of Electron because it has a smaller footprint. I built the app but never released it because I wasn't ready to support it. When GPT 5.6 came out earlier this month I pointed it at the old codebase and tasked it with rewriting that entire app (still in Rust using Tauri), modernizing, refactoring, and looking for any improvements that it could find. --- The app is a sneak peek of how an AI profanity filter might look like in the future. The ultimate integration would see it built into gaming platforms like Steam and PSN where it's not only transforming your speech on demand, but it's also able to transform incoming audio from your teammates into family friendly language so parents can feel better knowing their kids aren't being bombarded with slurs when they let them play online multiplayer games. I also imagine an incredible opportunity for voice licensing allowing users to pay to unlock voices of their favorite streamers, actors, athletes, and characters for a limited time. Who wouldn't want to sound like Samuel L. Jackson yelling about motherfucking noobs in their motherfucking lane? --- The biggest obstacle was code signing. I went through all the hurdles in 2024, paying for an expensive OV signing certificate and also paying for the Apple Developer program. For 2026 I decided that the OV signing certificate is a racket and I'm not going to pay for it again. I already have an Apple Developer account for another app so I didn't have to pay extra to sign the macOS build. For Windows, the SmartScreen warnings when installing the app are a drag, but you can just tap more info and install it anyway. https://bit.ly/4wsxdqW July 26, 2026 at 11:23PM

Show HN: SpinWin – A macOS menu bar app to visually rotate or spin any window SpinWin is an open source menu bar app to visually rotate any individual window. You can rotate / spin as many as you want one by one. I was scrolling reels when one came on where the content creator suggested "turning the phone upside down" for a portion. I was sitting at my mac, and decided to see if I could find something that did this. To my surprise, nothing exists, so I decided to build it. Turns out macOS doesn't provide any public API to do anything like this, so I wound up using the Accessibility API to move the target window offscreen, where it keeps rendering. Then we capture it's contents with ScreenCaptureKit, and display that on a transparent, borderless overlay window which has a CALayer to rotate it. It's written in Swift, open source, MIT license, and signed/notarized. Have fun - would love to hear your comments. https://bit.ly/4wjgGFH July 25, 2026 at 06:29PM

Show HN: Life Tile – Passive time tracker that shows your day as a Mondrian grid https://bit.ly/4fywEVa

Show HN: Life Tile – Passive time tracker that shows your day as a Mondrian grid Hi, I developed Life Tile for iPhone. It tracks your time passively and visualizes it as a Mondrian-style grid. It's a one-time purchase app with a 7-day trial. I was a user of a similar app named Life Cycle. Since the app hasn't been updated in a while, I tried to make a better app with my ideas and experiences. I used a big square timeline instead of a donut chart. And I added more useful views: tree-map, map, and list. You can use categorized activities with custom colors. The data never leaves a device. No account, No Server. It only supports data backup using iCloud. It was for privacy but it also makes the development easier. I added just one anonymous usage stat with TelemetryDeck. You can turn it off anytime. There were many technical difficulties. iOS location API (CLMonitor) is not 100% precise. And many difficult cases can't be handled automatically. For example, GPS blackout inside the subway, too many venues in a small region, and a huge location like an airport. So I improved many heuristics and tried my best for easy editing. Please check the App Store for the screenshots. Then you'll know why it's inspired by Mondrian. https://apple.co/44LtV60 July 24, 2026 at 01:13AM

Show HN: An MCP server that turns async-work practices into tools https://bit.ly/4gRAJpR

Show HN: An MCP server that turns async-work practices into tools More than a decade ago, I adopted the self-imposed rule, if I answer a question more than once, the third time I need to be able to answer with a URL. Today, I published one very large URL - a book distilling what I learned from helping people work remotely at GitHub, and I wanted to rethink my rule for the age of AI. What if, instead of a URL, I could create an interactive experience that could tailor the guidance to your particular situation? What I ended up building was an Open and Async Advisor MCP server. To install (in claude or any other AI): > claude mcp add open-async -- npx -y @open-and-async/mcp Transparently, yes, it's from a book I wrote which launched today, but the MCP server is open source and free to use. No purchase required. It knows the key principles of the book, and has specialized tools like `draft_decision_doc`, `convert_meeting_to_async`, `score_status_update`, `triage_sync_vs_async`. This is an experiment for me, and I'm genuinely curious if it's helpful for others. https://bit.ly/4b9bk7w July 21, 2026 at 05:06PM

Show HN: Superserve – Firecracker microVM sandboxes for long-running AI agents https://bit.ly/4wz3TPL

Show HN: Superserve – Firecracker microVM sandboxes for long-running AI agents Hey HN, I built Superserve, a compute layer that lets AI agents live inside isolated Firecracker microVMs with no session time limits. The problem I kept running into: most sandbox providers kill your agent after 24 hours. If you're running something autonomous that needs to work for days — refactoring a codebase, running tests in a loop — you're constantly fighting timeouts and rebuilding state. Superserve lets you snapshot a running VM at any point, fork it into parallel branches, and resume exactly where you left off. Each agent gets its own VM, no shared kernels. There's also a credentials broker so agents never touch raw API keys directly, and egress is locked to URLs you specify. You bring your own agent (Claude Code, Codex, etc.). We handle the durable compute underneath. TypeScript and Python SDKs, MCP support, open-source and self-hostable. Would love to hear feedback, especially from anyone building long-running agents. https://bit.ly/4vL0RXh July 21, 2026 at 11:59PM

Show HN: Ekko – post-quantum E2EE layer for Instagram, WhatsApp, Telegram Web https://bit.ly/4gJYoZi

Show HN: Ekko – post-quantum E2EE layer for Instagram, WhatsApp, Telegram Web Hi everyone, I am a big privacy activist and the amount of privacy concerns in the internet with the discussions around European Chat Control, Meta removing e2ee in Instagram and corporations harvesting personal data for AI training is on the rise. The closed source social media companies keep managing and storing our private keys, allowing them to effectively access all of our personal communications.. Many open source alternatives exist, but the problem I kept running into was not a lack of good private messengers. Signal, SimpleX, and other projects already do important work The problem was getting the people to move. A messenger is only useful when the person you need to reach is there. Asking friends, family, coworkers, or customers to abandon their existing chats is a very high barrier. Ekko takes a different approach. It runs as a browser extension on top of existing messengers. Both people still need Ekko, but they do not need to move their conversation. You can continue using the Instagram, WhatsApp, Telegram, or Messenger chat they already share. Actively building this and trying to achieve a seamless automatic encryption in the UI across all popular messengers and adding support across all browsers, IOS, android and social media.. Under the hood, Ekko uses hybrid X25519 + ML-KEM-768 and XChaCha20-Poly1305. Private keys are generated and kept on your device. You can claim an Ekko handle to make exchanging public keys easier, exchange invitations directly without an account, or self-host the public-key directory. Currently: - A Chromium browser extension, Experimental Firefox and Safari builds - Instagram, WhatsApp Web, Telegram Web, and Messenger integrations - A self-hostable key directory - Open-source client, protocol, and server code Early version Chrome Web Store: https://bit.ly/4fN1z1e... Source code: https://bit.ly/4fLTTMN Website and demo: https://bit.ly/4h7nqlt I would genuinely appreciate direct feedback especially from people familiar with applied cryptography, browser security, key verification, messenger integrations, potential solutions for iOS UI integration (faster than using browser w/ Safari extension) If you try it, please tell me what breaks or what feels confusing. Actively trying to make this better as a side project! If you discover a security issue, email kirill@useekko.app rather than posting it publicly. Looking for feedback! :) https://bit.ly/4h7nqlt July 21, 2026 at 01:39AM

Show HN: The0 – self-hosted runtime for trading bots, bring your own language https://bit.ly/4vHr1dp

Show HN: The0 – self-hosted runtime for trading bots, bring your own language So Im a solo developer who has always had an itch for algorithmic trading. Initially I started off learning how to trade algorithmically with Yves Hilpisch book "Python for Algorithmic Trading" after reading that book I was hooked and started building algorithmic trading bots. Initially these were separate python scripts that I ran on my local machine. That was a bad idea cause local machines are not reliable and I wanted to run my bots 24/7 365. In my actual career im a software engineer with experience in building distributed systems and fault tolerant web applications. I wasn't interested in deploying my code to managed services like MetaTrader, CTrader or QuantConnect etc because I wanted to have full control over my code and the environment it runs in. I also wanted to be able to run my bots in any programming language I wanted, not just Python. Sometimes I wanted to prototype a bot in Python and then rewrite it in C++ or Rust for performance reasons. Many at this point would have said why not use a framework like Lean or Freqtrade or Hummingbot. However I found that these frameworks were too opinionated and if you decide to use them then your bot is now part and parcel of their framework. I backtested my bots locally in my own specific way, and now with AI my agents can generate code, backtest and analyze the results all locally, no need to run any of it in the execution platform. I wanted bots I could deploy, version, update and monitor like any other software application. I also wanted to explore building something that creates a standardized way of running bots. This has been a 4 year journey and I made a lot of mistakes along the way. The application has seen 4 rearchitectures, 3 of which were basically complete rewrites. The first version was a python program and the bots were just modules that were loaded dynamically. The second was my serverless phase when I internally just wanted something that was online cron triggered and only works for me. The third was the first time I was dipping into kubernetes; more cloud native and the idiot in me decided to try make it a SaaS. The final form is a fully self-hosted runtime, api, cli and frontend that let you run bots as containers in a fault tolerant way both locally (through docker `the0 local`) and in a cluster (k8s) and monitor them with a minimalistic frontend. To support multiple languages there's a thin contract that the bots have to implement: a main(bot_id, config) function and a bot-config.yaml file. The runtime (written in Go) takes care of the rest, it supports C++, Rust, Python, JS/TS, C#, Scala and Haskell for those who are brave enough to try it. More on the architecture here: https://bit.ly/3TuNb57 If you want to play with the0 you can run it locally, guide here: https://bit.ly/4fbMKoV . The0 is open source and licensed under Apache-2.0: https://bit.ly/4wi6mOe I currently use the0 to run my own personal algorithmic trading bots on a single node k3s cluster on a $10/month Hetzner VPS. I have 18 bots running on 2 brokers (Alpaca, Bybit) and they have been running for months without issues. Some bots trade crypto, others stocks, some do risk analysis and others invest. Coolest bit is the API provides an MCP server so AI agents can query the state of the bots, look at their logs, monitor them and even update them. Slap an OpenClaw agent and you can effectively setup an autonomous AI quantitative trading system (good luck chasing Alpha). Now I must admit Lean has all the tools and far more quantitative prowess than the0, but I always felt it does too much. Each Lean engine runs one algorithm, and once you have lots of bots, running and managing all of them in production is left to you. That's the part the0 does, and its the only part it tries to do. If you find hiccups or have ideas for features Im all ears. More on the internals in my first comment. https://bit.ly/4wi6mOe July 20, 2026 at 02:49PM

I know there are already several HN summarizers on GitHub, and I tried some of them. They just didn't fit the workflow I wanted, so I decided to build my own. My project is a self-hosted app that automatically fetches top stories, summarizes them with AI, translates them into your preferred language, and prepares a personalized daily briefing in a nice customizable UI while you sleep. Maybe I'm not the only one who wanted this kind of workflow.

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 .

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?

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 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
