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 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 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.

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

Show HN: A platform to find people to jam on side projects with https://bit.ly/43wlQBf

Show HN: A platform to find people to jam on side projects with I have always found it funny how challenging it can be to find people to jam on side projects with. There are literally entire sub-Reddits where people post looking for someone to work on a project with. That is super inefficient. There are also newsletters for this (also pretty inefficient). Let's Jam is my attempt to solve this. This is NOT a cofounder matching platform. The idea is to connect people with ideas and skills so they can jam on them together. If they end up becoming cofounders, cool, but that is up to them. This is also NOT a place for freelancers to hunt job opportunities. Again, the platform is for people who have an idea or a skill and want to work on something together. How it works: > You either a) find a project and request to jam on it with that person, b) post a project and wait for someone to request to jam on it with you, c) claim an idea and wait for someone to request to jam on it with you. > Once someone requests to jam with you, you'll get an email, and you can vet them via LinkedIn or their past work. If you think they'll be a good fit then accept their request and they'll reach out to you. > That's it. Simple. Any feedback is greatly appreciated! https://bit.ly/4uo98As May 24, 2026 at 01:28AM

Show HN: Open-source private home security camera system (end-to-end encryption) Hey everyone, I'm back with some exciting updates. I previously introduced an open source private home security camera in 2024, which uses OpenMLS for end-to-end encryption. It was called Privastead then and it's now renamed to Secluso. John Kaczman found my project from here and has been working on it with me over the last year and half. We've made a lot of improvements to the software, which we would like to share with you: - You can now set this up on your Raspberry Pi in less than 5 minutes with no technical expertise using our easy-to-use GUI deploy tool. We've put together a comprehensive build-your-own guide that walks you through the required steps (you can find a link at the top of the repository README). - We use a customized, minimal OS based on the Yocto project for the camera. - Every part of our stack except for the iOS app has reproducible builds. This includes our Android app, camera/server binaries, deploy tool, and the aforementioned OS. - We've re-designed our mobile app, which is now on the iOS App Store and Google Play store. - We now support UnifiedPush for more privacy-preserving push notifications. Looking forward to seeing what you all think! https://bit.ly/4tKxUJT May 22, 2026 at 10:51PM

Show HN: Free Fonts – a collection of 400+ original, open-source typefaces https://bit.ly/4eVUv2x

Show HN: Free Fonts – a collection of 400+ original, open-source typefaces Hi HN! For the past few months I've been working up to this launch of Free Fonts - it's a collection of completely free, open source, and original fonts that can be used for any project, including commercial ones. The collection has over 400 fonts in a variety of novel styles, from simple sans serifs to decorative handwritten and blackletter fonts. It will also continue to be updated and grow over time. Designers and developers today have essentially two options when it comes to choosing and creating fonts. Either use a Google Font, which can be limited in terms of unique and novel selections, or pay a significant amount of money for font licenses from a few large players in the space like Monotype. The problem today is that it can be difficult to find a novel, unique font for an affordable price. Our hope is that this collection can be a starting point for solving this problem. What makes this project different is that every font in the collection was generated completely by AI, and is a novel set of letterforms. This is what makes it possible for me to launch the project with confidence that these fonts can be freely used in any type of project. The AI workflow behind this project is also accessible on the same site. Our model was trained on a variety of images across the internet and then runs a full pipeline to transform a consistent set of letters into a single downloadable TTF font file. It can be prompted from a text prompt, or a sample image that contains an image of some text. Font licensing is a complex world, and I deeply believe that it is ripe for a change. My hope is that this launch can spark a new conversation on the future of typography and how it can be freely and easily used by designers and developers over time. Hope that you enjoy, and would love your feedback about the project and also the fonts themselves. Eric https://bit.ly/4v71Uks May 22, 2026 at 12:57AM

Show HN: I made a tactical map-based WWII submarine simulator (public beta) https://bit.ly/4wMuppi

Show HN: I made a tactical map-based WWII submarine simulator (public beta) I've seen quite a few simming discussions on HN, so thought some of you might like this - I've created a map-centered, tactical submarine simulator and it's been a blast to make. I grew up playing Silent Service II on Atari ST with my dad, then got into Silent Hunter IV in the 2000s, and most recently have been loving the more recent UBoat. In each case, the part I always enjoy the most is the plotting and charting aspect - essentially beating uncertain estimates with geometry. So I decided to see how far I could get making my own sim that focused nearly entirely on that aspect. You listen on the hydrophone, estimate course and speed, identify ships through the periscope to get the mast height, use a working stadimeter for range estimates, and then try to build a good enough firing solution before getting discovered and hunted by any escorts. Things I'm particularly proud of are the working stadimeter, the dynamic music (Holst Mars stings when your torpedo is nearing a ship), and pretty intelligent destroyer logic. I've found great reference materials online and have modeled several of the gauges directly after actual submarine instruments. Tech-wise it’s a Vite/TypeScript app which enables me to offer the whole free version of the app as a browser version. The Steam page is here => https://bit.ly/3RnOge7 The landing page is here => https://bit.ly/4wGEPGR I plan on releasing a full version soonish, including a WWII campaign with progression, patrol zones, and much more on Steam (PC, Mac, Linux/Steam Deck), App Store (iPhone, iPad, Mac), and Play Store (Android). Would highly appreciate any feedback anyone has! https://bit.ly/3Pv6Iku May 18, 2026 at 04:08PM

Show HN: I reverse engineered Apple's video wallpapers https://bit.ly/4v0cMjQ

Show HN: I reverse engineered Apple's video wallpapers Ever since Apple introduced their video wallpapers I wanted to be able to put custom videos there. I decided to reverse engineer and see what I can do. I built Phosphene to sell it, but the existing competitors were polished enough that the time it would have taken to catch up wasn't going to pay off. So I'm open-sourcing it. WallpaperExtensionKit.framework is what powers macOS wallpapers. It controls what’s shows in the Settings app. It took a lot of trial and error to replicate the behavior, but the result is that your custom wallpapers appear alongside everything else. I wanted to have an “add” button there too, but I couldn’t find a way to do so, so there’s a companion app that will put your video where it needs to be. Unlike Apple's Aerials, the video keeps playing on the desktop (not just the lock screen). The renderer drives AVSampleBufferDisplayLayer directly with PTS-offset gapless looping, and pauses or downshifts based on thermal state, battery level, brightness, and window occlusion. It’s free and works well. https://bit.ly/4uYuDHQ May 21, 2026 at 12:54AM

Show HN: How to Kill the Dead Internet https://bit.ly/4uk2jQx

Show HN: How to Kill the Dead Internet Ok, so maybe "how to revive the internet" would be more accurate, but if you're reading this, I got your attention, right? Here's why I want you to read on: I built a free extension, D-slop, to disincentivize anyone from posting AI writing, and eventually images and video as well, on the internet. For writing, it checks known vocab and punctuation tells, as well as subtler tells related to cadence, and assigns it a score subject to an adjustable threshold. If the text fails, users have the option to flag offending text, hide it, or block the page entirely (with the option to see anyway). For media, it's admittedly fairly weak, as it relies on C2PA metadata which is stripped from all of the social media sites where it would be most helpful. (Anyone else have chronically online boomer parents continually gobbling up slop like it's real information?) I have a D-slop+ version in the works that should be able to handle the media itself, but it's going to have to make API calls to have real teeth, which means I can't offer it for free. If this extension validates the concept, I'm happy to build it for y'all. Yes, I vibe-coded it, but an ancillary bonus to the project accrued when it inspired me to cook dinner listening to Metallica's "Fight Fire with Fire," which in turn brought my 5 y/o running into the kitchen with every musical instrument in the house for an impromptu karaoke speed metal session. It's MIT license open-source, full brief at https://bit.ly/49RROvm ; This forum is full of people smarter than me, so I'm open to suggestions. https://bit.ly/4uRn71v May 18, 2026 at 02:35AM

Show HN: Serene Bach – a Go weblog engine that runs as CGI or HTTP I originally made Serene Bach in the 2000s as a weblog engine written in Perl CGI. I rebuilt it from scratch in Go as a single binary that can run either as a CGI program or as a normal HTTP server. I know CGI is generally considered legacy technology now, but I still rely on it for shared hosting. In this version, I added Markdown support, a responsive default theme, Open Graph image generation, and static output generation. It is still in beta, but the repository includes a Docker image published on GHCR, documentation, and a local quick start. I'd appreciate feedback from anyone interested in small self-hosted publishing tools, especially if you still care about shared hosting or CGI-style deployment. https://bit.ly/4dzexgV May 17, 2026 at 04:47AM

When looking at a large diff on Friday I pointed an llm at diffs.com and trees.software and told it to build an app. It only took 16 minutes, is extremely fast for large diffs, beautiful and minimal. Today I polished it up and added all the features that I need. It has file filters, search, an llm walkthrough mode, and review comments that you can paste back into your llm.

Show HN: SwarmWright, structured multi-agent AI defined in markdowns I had a bunch of custom AI pipelines and a growing folder of markdown files and Python scripts holding it together. Built this to give that chaos some structure. Agents are markdown files, topology is a JSON file the runtime enforces hard. The agents are still fully autonomous: they make their own decisions, but the graph they operate in isn't. You declare who can call whom upfront and the runtime holds that line.

Show HN: HYPD – AI co-pilot for marketers running Google Ads https://bit.ly/4tASBrQ

Show HN: HYPD – AI co-pilot for marketers running Google Ads We've been building HYPD for the last 1 year together with a small team in Berlin. It's an AI co-pilot (chatbot) for PPC freelancers and agencies. It connects to a Google Ads account, then runs audits, performs data analysis from natural language ("why did CAC jump last Tuesday"), generates ad copy grounded in account history and context, and exports reports and datasets. Thesis behind it: just like programming is "solved" but engineering is not, ad-ops and media buying will be solved, but account strategy and human creativity remain the leverage. Background: I founded PubNative (acquired by Verve Group), was Co-CEO at Verve Group, and for the last year we've been "taming" LLMs when working with structured and unstructured data. So far we got more than 200+ agencies and freelancers onboarded. Hard parts so far: (1) data accuracy, (2) understanding the gaps in LLM knowledge of the Google Ads API, (3) adding enough context to make answers fit what professional marketers expect. Free trial + free tier on the site. Happy to enable demo accounts for anyone who wants to test it without connecting their account. https://bit.ly/4eOAQlb May 13, 2026 at 10:09AM

Show HN: NodeDB – High Perfomance Multi-Model Database https://bit.ly/4d5meMY

Show HN: NodeDB – High Perfomance Multi-Model Database Hey HN, I've been working on a multi-model database called NodeDB. Originally, i've found out the idea of SurrealDB quite good. However, it doesn't have some graph and vector features that I need. And since it is just a KV wrapper, instead of purpose-built engine, the performance will never be close to the specialized databases (like Neo4j, Pinecone, Clickhouse, etc). And i've asked myself, what if, there is a database that have the same idea, but built differently? Instead of just treating it as KV database, we build specialized engines for the data. Besides that, I want it to be able to support my IOT/edge project, where i need offline sync capabilities (Currentyl still in progress). Will it work? I put it into test. I've been experimenting and researching for a year, creating multiple versions, and then I created NodeDB. Disclaimer: It is still in public beta (as of May 2026), but it really excites me if I can make this db work. And I use AI as assistant for coding and planning. It is nearly impossible to do as a solo developer without any AI assistance. Would love feedback from HN: - Are there specific features or improvements that would make it more useful? If you're interested in experimenting or contributing, the repo is here: GitHub Repo: https://bit.ly/4nlpE1s Looking forward to your thoughts! https://bit.ly/4nlpE1s May 12, 2026 at 12:21AM

Show HN: adamsreview – better multi-agent PR reviews for Claude Code https://bit.ly/4dBFSjG

Show HN: adamsreview – better multi-agent PR reviews for Claude Code I built adamsreview, a Claude Code plugin that runs deeper, multi-stage PR reviews using parallel sub-agents, validation passes, persistent JSON state, and optional ensemble review via Codex CLI and PR bot comments. On my own PRs, it has been catching dramatically more real bugs than Claude’s built-in /review, /ultrareview, CodeRabbit, Greptile, and Codex’s built-in review, while producing fewer false positives. adamsreview is six Claude Code slash commands packaged as a plugin: review, codex-review, add, promote, walkthrough, and fix. I modeled it after the built-in /review command and extended it meaningfully. You can clear context between review stages because state is stored in JSON artifacts on disk, with built-in scripts for keeping it updated. The walkthrough command uses Claude’s AskUserQuestion feature to walk you through uncertain findings or items needing human review one by one. Then, the fix command dispatches per-fix-group agents and re-reviews the work with Opus, reverting any regressions before committing survivors. It runs against your regular Claude Code subscription (Max plan recommended), unlike /ultrareview, which charges against your Extra Usage pool. I would love feedback from Claude Code users, pro devs, and anyone with strong opinions about AI code reviews.

Show HN: Ant – A from-scratch JavaScript runtime in 9 MB https://bit.ly/3RuEEy1

Show HN: Ant – A from-scratch JavaScript runtime in 9 MB Hey HN! I have been working on Ant for a while now, would love to share around now. What is Ant? It's my JavaScript runtime, built from scratch over many hours of work. Much effort has gone into keeping the binary size small, around 9MB at the moment (6.5 MB with -Os). On my M4 Pro, the hono coldstart bench (examples/npm/hono/bench-coldstart.js) lands around 5ms, about 2.4x faster than bun, and 5.8x faster than node. To keep things small, the engine ("Ant Silver") is hand-written, not a wrapper around V8/JSC/SpiderMonkey. The JIT is still a work in progress but it uses a fork of MIR as the backend. Ant currently targets the WinterTC Minimum Common API, while also passing 100% the javascript-zoo compat-table tests, and is sitting around 64% on test262. Why did I build Ant? Well, I wanted a runtime small enough to ship with CLI's and small Docker containers without having to drag along 50 to 100mb of just runtime. Ant in its current state is performant enough in some cases to compete with v8, but mostly in specific shapes. Background on how it got here: https://bit.ly/4djc7Tv Online demo shell/container: https://bit.ly/4nmoiUe If anyone has questions about Ant, such as the engine, im happy to answer any of them! Feedback is also appreciated, if you run your own code and hit some edge case. https://bit.ly/3Rvp84Y May 9, 2026 at 03:31AM

Show HN: Armorer – A secure local control plane for AI agents https://bit.ly/4f3W7Hu

Show HN: Armorer – A secure local control plane for AI agents Hey HN, I built Armorer because I was tired of two things: 1. The absolute "dependency hell" of setting up new AI agents (Codex, OpenClaw, etc.). 2. The security risk of giving powerful local agents broad access to my host machine. Armorer is a secure local control plane that manages the lifecycle of your agents. It uses Docker for true process isolation and provides a unified UI/CLI for monitoring and job tracking.

Show HN: Dreamwork – a job search site I made after Indeed fired my pregnant wif https://bit.ly/4tVTzjf

Show HN: Dreamwork – a job search site I made after Indeed fired my pregnant wif Hey, I’m Colin and I have a fun story for you. My 7 month pregnant wife was laid off from Indeed (she was a PM there) back in December. This pissed me off quite a bit, as she was supposed to get 6 months leave and instead got fired. So I spent the last five months working part time to build Dreamwork, a platform aiming to make the job search experience actually better with AI (not just mass application spam). I started with just a telegram bot doing scraping, then advanced to Google Embeddings 2.0 for vectorizing the jobs, built out a tight 6 axis scorecard for both the user and each job. Then I actually got to use my English degree (lol) to optimize the prompt for custom per-job resumes and cover letters to make them not sound like - again - shitty AI. Most AI cover letters have a kind of consistently dead quality. They use all the keywords and somehow communicate nothing. I absolutely hate that, so I’ve been fairly obsessive about making the output feel more like a decent human draft: specific but restrained, and not stuffed with keywords. It is now useful enough that I think strangers can try it and find serious value. What it does today: - indexes ~100k curated tech jobs - tries to avoid stale/duplicate aggregator garbage - uses semantic matching instead of only keyword search - generates an “application pack” for each job: tailored resume, cover letter, and answers to common/custom questions - lets the user edit everything before applying - helps keep track of saved jobs and generated materials Auto apply is the part I’m conflicted about. I do t think blindly spraying applications is good for the candidates (chance of hiring is already low, even with hard work and customization), recruiters (they’re swamped), or the world (we don’t need more slop). I’ll build auto apply out in some format, but I want to be thoughtful about it. I also built out a whole research section to map out layoffs and hiring trends. This will start to be super useful in a month or two. Anyways - it’s all free to use right now. Built originally out of spite, now becoming a real product. I’d love to get feedback on what elements would truly make this the career companion you’re looking for. Not - resume spray and pray platform, but something that will actually help you navigate this insane hiring economy we’re in.

Show HN: I indexed 8,643 BSides talks across 227 chapters and 6 continents https://bit.ly/4tQWbyL

Show HN: I indexed 8,643 BSides talks across 227 chapters and 6 continents Hi HN, I'm Roland, and for the past few weeks, I've been building AllBSides — a directory of every BSides conference talk uploaded to YouTube. As of today, 8,643 talks from 5,927 speakers across 227 chapters in 68 countries. Combined runtime is 280 days. The transcripts come to about 60 million words. The archive came together in stages: 1. Manually map every BSides chapter's YouTube channel 2. Pull every video and transcript from Supabase 3. Run each transcript through Haiku for tag extraction (tools, topics, difficulty, team, talk style, research method, and much more) 4. Run results through Sonnet for categorization and dedup 5. Final pass goes through Opus for verification 6. Do a manual verification - at one time, the pipeline showed over 16k AI suggestions for manual verification. Today, most are resolved. Total LLM cost so far: about €200. The whole pipeline is rebuildable from scratch. Each talk gets its own page with embedded video, full transcript, speakers, tags, and "related talks." Each tool/framework/protocol/standard mentioned across the corpus gets its own page (3,968 distinct technologies tracked). Some interesting facts I gathered while building it: -(A) The site is currently 94% bot traffic. Of that, about 80,000 hits/month are AI training crawlers (ClaudeBot, GPTBot, meta-externalagent). Within 7 days of the talks archive going live, all major AI labs had ingested the entire corpus. The discovery cascade was startling to watch in real time. -(B) The taxonomy work was the hardest part. Distinguishing "tools" from "frameworks" from "protocols" from "concepts" sounds easy until you have 5,000 ambiguous extracted entities. The 3-tier LLM pipeline helped a lot — Haiku alone was too noisy, Opus alone was too expensive. -(C) Top tools mentioned: Wireshark (343), PowerShell (342), Metasploit (332), Burp Suite (322), GitHub (296), VirusTotal (273), Docker (253), Splunk (251), Nmap (247), MITRE ATT&CK (237). The list reflects what BSides talks actually discuss, not what vendors curate. -(D) May is the peak BSides month — 29 events, 17% of all events with dates. -(E) The top 1% of talks (86 videos by view count) account for 51% of all viewership. The other 99% are deeply niche, often the only video record of a specific technique. The stack is intentionally lean: Go, SQLite, vanilla JavaScript, BunnyCDN. Static rendering at build time. No frameworks, no client-side state. The site costs about €50/month to run. The data behind this post and much more can be found in the site footer, under the link "stats". Happy to answer questions about the data pipeline, the taxonomy decisions, or what the AI crawler patterns looked like as the archive went live. Feedback on what to build next is genuinely welcome — I'm a solo dev figuring this out as I go. — Roland (parkado) https://bit.ly/4tPx930 May 4, 2026 at 11:10PM

Show HN: Kula – a family health platform that makes sense of your data https://bit.ly/4tQmIfS

Show HN: Kula – a family health platform that makes sense of your data My parents are in India, I'm in the US. Their health system was continuous WhatsApp photos of lab reports, vague updates over the phone, and me finding out about doctor visits weeks later. So I built Kula. Upload lab reports (photo, PDF, WhatsApp forward) and it have them parsed and track trends. Connect a wearable and track daily health signals as well as your baselines. Everything goes into one record you can search and review over time. There's a chat layer where you can ask questions in plain language like, "what's my dad's cholesterol trend showing", and get a sourced answer from your own data. Primarily built it for my family. My parents told me they'd use it even without me, just to have their records organized before doctor visits. That truly changed how I think about it. Looking for feedback on this platform. Would you use this? What are your thoughts? What's missing? https://bit.ly/4cP9HNA May 4, 2026 at 05:40AM

Show HN: Use an Android Phone as an HTTP Proxy https://bit.ly/4upfSNZ

Show HN: Use an Android Phone as an HTTP Proxy I created a simple project to allow you to use a phone as a web proxy. This is not a proxy for the phone, its a way to proxy web traffic from elsewhere via the phone. One practical use case is accessing geo-restricted content. If you have a trusted contact in the country with an Android phone, this can serve as a simple alternative to a commercial VPN. To set it up you need to run a proxy server which can run as a docker container. You then need to install the app on the Android phone which will connect to the server. Finally you configure a browser to use the proxy server as the HTTP/HTTPS proxy.

Show HN: Code on the Go, an IDE for Android with On-Device Debugging (GPLv3) https://bit.ly/4ueQ3jI

Show HN: Code on the Go, an IDE for Android with On-Device Debugging (GPLv3) Hi HN, I’m Hal, the CTO at App Dev for All. I wanted to share a technical problem we worked on over the past year and how we approached it. We’ve been building Code on the Go, a full-featured IDE that runs entirely on an Android phone. No laptop, no ADB connection, no cloud build server. It compiles projects locally on the device using Gradle, supports Java and Kotlin with LSP, and includes a debugger that runs on the same phone as the app being tested. The most interesting and challenging part ended up being the debugger. The Android OS has a rigorous security model, which can get in the way of traditional inter-process communication. Android debugging assumes ADB, which assumes two machines. We bypassed ADB entirely, attaching the JDWP agent to the target process at launch and routing its output to our debugger over a local socket. We used a scoped adaptation of the Shizuku project to get the necessary system access without requiring root. We also had a few other technical challenges with Code on the Go: Sketch-to-UI (generates Android XML from a photo of a hand-drawn layout, runs fully offline with Yolo), an optional Gemini-powered coding agent (opt-in, requires your own API key), and a plugin system with isolated class loaders. One of our pre-release community members has used it to build and publish a Sinhala/English keyboard app to the Play Store, built entirely on his phone. This served as our test case for Play Store compatibility. We are a philanthropic venture. No ads, no tracking, no subscription. License is GPLv3. APK: https://bit.ly/4dgfOdH Source: https://bit.ly/423N8P1 Happy to answer questions on the implementation. https://bit.ly/3QGOTze April 30, 2026 at 11:17PM

Show HN: RoboAPI – A unified REST API for robots, like Stripe but for hardware https://bit.ly/3Qv1DbY

Show HN: RoboAPI – A unified REST API for robots, like Stripe but for hardware Every robot manufacturer ships a different SDK and a different protocol. A Boston Dynamics Spot speaks nothing like a Universal Robots arm. Every team building on top of robots rewrites the same integration layer from scratch. This is a massive tax on the industry. RoboAPI is a unified API layer that abstracts all of that into one clean developer experience. One SDK, one API key, any robot — simulated or real hardware. You can connect a simulated robot and read live telemetry in under 5 minutes: pip install fastapi uvicorn roslibpy uvicorn api.main:app --reload curl -X POST localhost:8000/v1/robots/connect -d '{"robot_id":"bot-01","brand":"simulated"}' curl localhost:8000/v1/robots/bot-01/sense It also connects to real ROS2 robots via rosbridge — I tested it today controlling a turtlesim robot drawing circles through the API. The architecture is pluggable — each robot brand is a separate adapter implementing a common interface (like a payment gateway in Stripe). Adding a new brand means one file. Currently supports: simulated robots and any ROS2 robot. Boston Dynamics and Universal Robots adapters are next. Would love feedback from anyone working in robotics — especially on the API design and what's missing for real-world use. https://bit.ly/3QyRJWM April 25, 2026 at 12:16AM

Show HN: Nimbus – Browser with Claude Code UX https://bit.ly/41XYTX5

Show HN: Nimbus – Browser with Claude Code UX Hi HN, I'm Anil. Nimbus is a desktop browser with an AI agent built into it. The UX is shamelessly inspired by Claude Code: a chat bar at the bottom, an agent log above it, and the webpage itself when its needed. This is mainly a UX experiment for me. And also the reason it isn't a Chrome extension: once you have a chat bar that understands intent, the URL field is redundant. You shouldn't have two places to tell the browser what you want. I didn't want to bolt an agent onto an existing browser's chrome and end up with duplicated controls everywhere — I wanted full freedom to redesign the shell from scratch, decide what stays, what goes, and what a browser even looks like when the agent is the primary interface.

Show HN: I built a toy that plays grandma's stories when my daughter hugs it https://bit.ly/4d3RGLe

Show HN: I built a toy that plays grandma's stories when my daughter hugs it This was a project I built for my daughter's first birthday present. For context, I'm a surgical resident in the UK by background and am currently taking a year out of training to study a masters in computer science. My daughter just turned one. There are two things she really loves: the first is particular soft toy that she just can't live without, and the other is a good story book. Her grandparents live hours away and I didn't want her to forget what they sound like between visits. I wanted her to hear them whenever she missed them. My parents brought my brother and I up with incredible stories and books from all sorts of cultures, many of the stories being passed down from their parents before them. I didn't want my daughter to miss out on that. Finally, I was sick of missing storytime with her when I had to leave for night shifts. I wanted her to hear my voice before she slept every night. For all these reasons, I decided to build Storyfriend. It's her favourite soft toy with a custom made speaker-module inside. I combined my surgical skills with the skills I was learning as a CS student. Along the way I dipped my toes into the world of 3D printing, CAD and electronics design. When she hugs the toy, it plays stories read by her grandparents. She can take the toy with her anywhere and hear the stories anytime she wants - it works offline and has internal storage. It meets my wife's strict no-screen rule (which is getting harder to stick to as the days go by). I've recorded some of the stories that we would read together, so that on nights when I'm working she still has me there to read her a bedtime story. The bit I'm most pleased with: grandparents don't need an app. They just call a phone number. The audio routes through my server and pushes to the toy over WiFi. My own 86-year old grandmother in a rural village in another country can do it by just making a regular call via her landline, as she has done for many years - no help needed, no apps required, no smartphones involved. Hardware is a BLE/wifi module with a MAX98357 chip and custome battery management system, all soldered together, placed in a 3D printed enclosure and placed into a compartment that I stitched into her cuddly toy. Firmware pulls new messages when connected to WiFi and stores them on an SD card. So far I've sold a few hand-made units to parents and grandparents who resonated with the project.

Show HN: Mediator.ai – Using Nash bargaining and LLMs to systematize fairness https://bit.ly/3OG1lhI

Show HN: Mediator.ai – Using Nash bargaining and LLMs to systematize fairness Eight years ago, my then-fiancée and I decided to get a prenup, so we hired a local mediator. The meetings were useful, but I felt there was no systematic process to produce a final agreement. So I started to think about this problem, and after a bit of research, I discovered the Nash bargaining solution. Yet if John Nash had solved negotiation in the 1950s, why did it seem like nobody was using it today? The issue was that Nash's solution required that each party to the negotiation provide a "utility function", which could take a set of deal terms and produce a utility number. But even experts have trouble producing such functions for non-trivial negotiations. A few years passed and LLMs appeared, and about a year ago I realized that while LLMs aren’t good at directly producing utility estimates, they are good at doing comparisons, and this can be used to estimate utilities of draft agreements. This is the basis for Mediator.ai, which I soft-launched over the weekend. Be interviewed by an LLM to capture your preferences and then invite the other party or parties to do the same. These preferences are then used as the fitness function for a genetic algorithm to find an agreement all parties are likely to agree to.

Show HN: Palmier – bridge your AI agents and your phone https://bit.ly/4d0ATb5

Show HN: Palmier – bridge your AI agents and your phone Hi HN — I built Palmier. Palmier bridges your AI agents and your phone. It does two things: 1. It lets you use your phone to directly control AI agents running on your computer, from anywhere. 2. It gives your AI agents access to your phone, wherever you are — including things like push notifications, SMS, calendar, contacts, sending email, creating calendar events, location, and more. A few details: * Supports 15+ agent CLIs * Supports Linux, Windows, and macOS * What runs on your computer and your phone is fully open source * Works out of the box — no need to set up GCP or API keys just to let agents use phone capabilities * Your phone can act as an agent remote: start tasks, check progress, review results, and respond to requests while away from your desk * Your phone can also act as an agent tool: agents can reach into phone capabilities directly when needed * Optional MCP server: if you want, Palmier exposes an MCP endpoint so your agent can access phone capabilities as native MCP tools. This is optional — you can also use Palmier directly from the phone app/PWA, with those capabilities already built in * Still in alpha stage, with bugs. Opinions and bug reports very welcome The basic idea is that AI agents become much more useful if they can both: * interact with the device you actually carry around all day * be controlled when you are away from your computer Palmier is my attempt at that bridge. It already works with agent CLIs like Claude Code, Gemini CLI, Codex CLI, Cursor CLI, OpenClaw, and others. You can run tasks on demand, on a schedule, or in response to events. Would especially love feedback on: * whether this feels genuinely useful * which phone capabilities are most valuable * which agent CLIs I should support next * what feels broken, awkward, or confusing Site: https://bit.ly/42omNLm Github: * https://bit.ly/48TuQn5 * https://bit.ly/3Qd8CGx Happy to answer questions. https://bit.ly/48TuQn5 April 21, 2026 at 03:31AM

The original requires CUDA with flash_attn, nvdiffrast, and custom sparse convolution kernels: none of which work on Mac. I replaced the CUDA-specific ops with pure-PyTorch alternatives: a gather-scatter sparse 3D convolution, SDPA attention for sparse transformers, and a Python-based mesh extraction replacing CUDA hashmap operations. Total changes are a few hundred lines across 9 files. Generates ~400K vertex meshes from single photos in about 3.5 minutes on M4 Pro (24GB). Not as fast as H100 (where it takes seconds), but it works offline with no cloud dependency. https://bit.ly/4cB0fvE https://bit.ly/4cB0fvE April 20, 2026 at 01:07AM

Show HN: Coelanox – auditable inference runtime in Rust (BERT runs today) https://bit.ly/3OMabe0

Show HN: Coelanox – auditable inference runtime in Rust (BERT runs today) PyTorch and ONNX Runtime tell you what came out. They can't tell you what actually ran to get there — which ops executed, in what order, on what inputs. A model gets packaged into a sealed .cnox container. SHA-256 is verified before a single op executes. Inference walks a fixed plan over a minimal opset. Every run can emit a per-op audit log: op type, output tensor hash, output sample — cryptographically linked to the exact container and input that produced it. If something goes wrong in production, you have a trail. Scalar backend today — reference implementation and permanent fallback when hardware acceleration isn't available. Audit and verification is identical across all backends. SIMD next, GPU after that. Input below is synthetic (all-ones) — pipeline is identical with real inputs. github.com/Coelanox/CLF Audit example: { "schema": 2, "run": { "run_id": "59144ede-5a27-4dff-bc25-94abade5b215", "started_at_unix_ms": 1776535116721, "container_path": "/home/shark/cnox/models/output/bert_base_uncased.cnox", "container_sha256_hex": "184c291595536e3ef69b9a6a324ad5ee4d0cef21cc95188e4cfdedb7f1f82740", "backend": "scalar" }, "input": { "len": 98304, "sha256_hex": "54ac99d2a36ac55b4619119ee26c36ec2868552933d27d519e0f9fd128b7319f", "sample_head": [ 1.0, 1.0, 1.0, 1.0 ] }, "ops": [ { "op_index": 0, "op_type": "Add", "out_len": 98304, "out_sample_head": [ 0.12242669, -4.970478, 2.8673656, 5.450008 ], "out_sha256_hex": "19f8aa0a618e5513aed4603a7aae2a333c3287368050e76d4aca0f83fb220e78" }, { "op_index": 1, "op_type": "Add", "out_len": 98304, "out_sample_head": [ 0.9650015, 0.23414998, 1.539839, 0.30231553 ], "out_sha256_hex": "7ae2f025c8acf67b8232e694dd43caf3b479eb078366787e4fdc16d651450ad4" }, { "op_index": 2, "op_type": "MatMul", "out_len": 98304, "out_sample_head": [ 1.0307425, 0.19207191, 1.5278282, 0.3000223 ], "out_sha256_hex": "44c28e64441987b8f0516d77f45ad892750b3e5b3916770d3baa5f2289e41bdd" }, { "op_index": 3, "op_type": "Gelu", "out_len": 393216, "out_sample_head": [ 0.68828076, -0.0033473556, 1.591219, -0.16837223 ], "audit_elided": "hash_skipped: len 393216 > max 262144" } https://bit.ly/4mEV1DY April 18, 2026 at 09:37PM

Show HN: Sostactic – polynomial inequalities using sums-of-squares in Lean https://bit.ly/4vAzfFm

Show HN: Sostactic – polynomial inequalities using sums-of-squares in Lean Current support for nonlinear inequalities in Lean is quite limited. This package attempts to solve this. It contains a collection of Lean4 tactics for proving polynomial inequalities via sum-of-squares (SOS) decompositions, powered by a Python backend. You can use it via Python or Lean. These tactics are significantly more powerful than `nlinarith` and `positivity` -- i.e., they can prove inequalities they cannot. In theory, they can be used to prove any of the following types of statements - prove that a polynomial is nonnegative globally - prove that a polynomial is nonnegative over a semialgebraic set (i.e., defined by a set of polynomial inequalities) - prove that a semialgebraic set is empty, i.e., that a system of polynomial inequalities is infeasible The underlying theory is based on the following observation: if a polynomial can be written as a sum of squares of other polynomials, then it is nonnegative everywhere. Theorems proving the existence of such decompositions were one of the landmark achievements of real algebraic geometry in the 20th century, and its connection to semidefinite programming in the 21st century made it a practical computational tool, and is what this software does in the background. https://bit.ly/4cSeiOP April 18, 2026 at 11:36PM

Show HN: I built a Wikipedia based AI deduction game I haven't seen anything like this so I decided to build it in a weekend. How it works: You see a bunch of things pulled from Wikipedia displayed on cards. You ask yes or no questions to figure out which card is the secret article. The AI model has access to the image and wiki text and it's own knowledge to answer your question. Happy to have my credits burned for the day but I'll probably have to make this paid at some point so enjoy. I found it's not easy to get cheap+fast+good responses but the tech is getting there. Most of the prompts are running through Groq infra or hitting a cache keyed by a normalization of the prompt. https://bit.ly/4muibN6 April 16, 2026 at 01:13AM

Show HN: OpenRig – agent harness that runs Claude Code and Codex as one system https://bit.ly/4812UgQ

Show HN: OpenRig – agent harness that runs Claude Code and Codex as one system I've been running Claude Code and Codex together every day. At some point I figured out you can use tmux to let them talk to each other, so I started doing that. Once they could coordinate, I kept adding more agents. Before long I had a whole team working together. But any time I rebooted my machine, the whole thing was gone. Not just the tabs. The way they were wired up, what each one was doing, all of it. Nothing I'd found treats your agent setup as a topology, as something with a shape you can save and bring back. So I built OpenRig, a multi-agent harness. A harness wraps a model. A "rig" wraps your harnesses. You describe your team in a YAML file, boot it with one command, and get a live topology you can see, click into, save, and bring back by name. Claude Code and Codex run together in the same rig. tmux is still doing the talking underneath. I didn't try to add a fancier messaging layer on top. The project is still early. My own setup uses the config layer extensively (YAML, Markdown, JSON) for prototyping functionality that outpace what's shipped in the repo and npm package. But the core primitives are there and the happy path in readme works. It's built to be driven by your agent, not by you typing commands by hand.

Show HN: Mcptube – Karpathy's LLM Wiki idea applied to YouTube videos https://bit.ly/4cbiR6A

Show HN: Mcptube – Karpathy's LLM Wiki idea applied to YouTube videos I watch a lot of Stanford/Berkeley lectures and YouTube content on AI agents, MCP, and security. Got tired of scrubbing through hour-long videos to find one explanation. Built v1 of mcptube a few months ago. It performs transcript search and implements Q&A as an MCP server. It got traction (34 stars, my first open-source PR, some notable stargazers like CEO of Trail of Bits). But v1 re-searched raw chunks from scratch every query. So I rebuilt it. v2 (mcptube-vision) follows Karpathy's LLM Wiki pattern. At ingest time, it extracts transcripts, detects scene changes with ffmpeg, describes key frames via a vision model, and writes structured wiki pages. Knowledge compounds across videos rather than being re-discovered. FTS5 + a two-stage agent (narrow then reason) for retrieval. MCPTube works both as CLI (BYOK) and MCP server. I tested MCPTube with Claude Code, Claude Desktop, VS Code Copilot, Cursor, and others. Zero API key needed server-side. Coming soon: I am also building SaaS platform. This platform supports playlist ingestion, team wikis, etc. I like to share early access signup: https://bit.ly/4c9lC8r Happy to discuss architecture tradeoffs — FTS5 vs vectors, file-based wiki vs DB, scene-change vs fixed-interval sampling. Give it a try via `pip install mcptube`. Also, please do star the repo if you enjoy my contribution ( https://bit.ly/4vthsjo ) https://bit.ly/4vthsjo April 13, 2026 at 05:34PM

Show HN: Lint-AI by RooAGI, a Rust CLI for AI Doc Retrieval https://bit.ly/4tMnxpr

Show HN: Lint-AI by RooAGI, a Rust CLI for AI Doc Retrieval We’re RooAGI. We built Lint-AI, a Rust CLI for indexing and retrieving evidence from large AI-generated corpora. As AI systems create more task notes, traces, and reports, storing documents isn’t the only challenge. The real problem is finding the right evidence when the same idea appears in multiple places, often with different wording. Lint-AI is our current retrieval layer for that problem. What Lint-AI does currently: * Indexes large documentation corpora. * Extracts lightweight entities and important terms. * Supports hybrid retrieval using lexical, entity, term, and graph-aware scoring * Returns chunk-level evidence with --llm-context for downstream reviewer / LLM * Use exports doc, chunk, and entity graphs. Example: * ./lint-ai /path/to/docs --llm-context "where docs describe the same concept differently" --result-count 8 --simplified That command does not decide whether documents are in contradiction. It retrieves the most relevant chunks so that a reviewer layer can compare them. Repo: https://bit.ly/48N8l3d We’d appreciate feedback on: * Retrieval/ranking design for documentation corpora. * How to evaluate evidence retrieval quality for alignment workflows. * What kinds of entity/relationship modeling would actually be useful here?

Show HN: Toy Python Lisp interpreters based on the 1960 McCarthy paper https://bit.ly/4dCFhPj

Show HN: Toy Python Lisp interpreters based on the 1960 McCarthy paper I wrote this set of Python files to try to help programmers understand the original LISP paper, assuming zero mathematical or Lisp knowledge. The original paper is a mind-blowing piece of computer science history for many reasons - I'd recommend anyone to try and get their head around it. I found plenty of fantastic LISP implementations which stay close to the original paper. But they are all fully-functional, practical implementations. The original paper builds from deeper fundamentals which it would be possible to write code in, albeit very impractical. I implemented these earlier iterations, so programmers can follow the paper step-by-step in a more familiar language than 50s mathematical notation. I am no expert in Lisp or mathematics, and intentionally went into this with no knowledge of Lisp beyond the original paper. I did not write it in the most elegant way, but in the simplest way for me to understand. So please don't take this code as a definitive statement on the language. However, this code really helped me to understand the original paper better, and to begin using Lisp with a better grasp of the spirit of the language. I'd welcome any thoughts from those who have more experience with Lisp or comp sci history. https://bit.ly/4dCFj9T April 12, 2026 at 11:01AM

Show HN: Bullseye2D – A Dart library for cross-platform 2D games https://bit.ly/4tHZp7t

Show HN: Bullseye2D – A Dart library for cross-platform 2D games I posted this here about a year ago, but I just pushed a 2.0 release, so I hope you don't mind a second look :) Bullseye2D is a 2D game library for Dart with a very simple API. The new version now supports multi-platform. It compiles to the web via a WebGL2 renderer, or natively to Windows, macOS and Linux through an SDL3 backend (which itself supports Vulkan, DirectX, Metal, and OpenGL renderers). It doesn't depend on Flutter and has very few dependencies (except SDL3). It mostly provides a minimal foundation that you can build your own abstractions on top of. This was also my first time leaning more heavily on AI (Opus) for a large refactor. I tried to review and test everything as good as I could, but honestly for the restructuring parts where I had the AI produce rather big chunks of code, I found reviewing and testing quite exhausting, and I still have a slightly queasy feeling about it. So this is also quite an experiment for me how good I'm able to utilise AI :) https://bit.ly/4tBTHnn https://bit.ly/4ciUyCn April 12, 2026 at 09:39AM

Show HN: HyperFlow – A self-improving agent framework built on LangGraph https://bit.ly/4vhTPdr

Show HN: HyperFlow – A self-improving agent framework built on LangGraph Hi HN, I am Umer. I recently built an experimental framework called HyperFlow to explore the idea of self-improving AI agents. Usually, when an agent fails a task, we developers step in to manually tweak the prompt or adjust the code logic. I wanted to see if an agent could automate its own improvement loop. Built on LangChain and LangGraph, HyperFlow uses two agents: - A TaskAgent that solves the domain problem. - A MetaAgent that acts as the improver. The MetaAgent looks at the TaskAgent's evaluation logs, rewrites the underlying Python code, tools, and prompt files, and then tests the new version in an isolated sandbox (like Docker). Over several generations, it saves the versions that achieve the highest scores to an archive. It is highly experimental right now, but the architecture is heavily inspired by the recent HyperAgents paper (Meta Research, 2026). I would love to hear your feedback on the architecture, your thoughts on self-referential agents, or answer any questions you might have!

Show HN: SmolVM – open-source sandbox for coding and computer-use agents SmolVM is an open-source local sandbox for AI agents on macOS and Linux. I started building it because agent workflows need more than isolated code execution. They need a reusable environment: write files in one step, come back later, snapshot state, pause/resume, and increasingly interact with browsers or full desktop environments. Right now SmolVM is a Python SDK and CLI focused on local developer experience. Current features include: - local sandbox environments - macOS and Linux support - snapshotting - pause/resume - persistent environments across turns Install: ``` curl -sSL https://bit.ly/4edpkzh | bash smolvm ``` I’d love feedback from people building coding agents or computer-use agents. Interested in what feels missing, what feels clunky, and what you’d expect from a sandbox like this. https://bit.ly/4ckmAxC April 10, 2026 at 01:01AM

Show HN: CSS Studio. Design by hand, code by agent Hi HN! I've just released CSS Studio, a design tool that lives on your site, runs on your browser, sends updates to your existing AI agent, which edits any codebase. You can actually play around with the latest version directly on the site. Technically, the way this works is you view your site in dev mode and start editing it. In your agent, you can run /studio which then polls (or uses Claude Channels) an MCP server. Changes are streamed as JSON via the MCP, along with some viewport and URL information, and the skill has some instructions on how best to implement them. It contains a lot of the tools you'd expect from a visual editing tool, like text editing, styles and an animation timeline editor. https://bit.ly/4t4hwoe April 9, 2026 at 12:23PM

You get a small chat overlay on every page. Ask it about the page and it (usually) figures out which tools to call. It has a thinking mode that shows chain-of-thought reasoning as it works. It's a 2B model in a browser. It works for simple page questions and running JavaScript, but multi-step tool chains are unreliable and it sometimes ignores its tools entirely. The agent loop has zero external dependencies and can be extracted as a standalone library if anyone wants to experiment with it. https://bit.ly/4m9Rw8a April 6, 2026 at 01:14AM

Show HN: Travel Hacking Toolkit – Points search and trip planning with AI https://bit.ly/4sRO5W7

Show HN: Travel Hacking Toolkit – Points search and trip planning with AI I use points and miles for most of my travel. Every booking comes down to the same decision: use points or pay cash? To answer that, you need award availability across multiple programs, cash prices, your current balances, transfer partner ratios, and the math to compare them. I got tired of doing it manually across a dozen tabs. This toolkit teaches Claude Code and OpenCode how to do it. 7 skills (markdown files with API docs and curl examples) and 6 MCP servers (real-time tools the AI calls directly). It searches award flights across 25+ mileage programs (Seats.aero), compares cash prices (Google Flights, Skiplagged, Kiwi.com, Duffel), pulls your loyalty balances (AwardWallet), searches hotels (Trivago, LiteAPI, Airbnb, Booking.com), finds ferry routes across 33 countries, and looks up weird hidden gems near your destination (Atlas Obscura). Reference data is included: transfer partner ratios for Chase UR, Amex MR, Bilt, Capital One, and Citi TY. Point valuations sourced from TPG, Upgraded Points, OMAAT, and View From The Wing. Alliance membership, sweet spot redemptions, booking windows, hotel chain brand lookups. 5 of the 6 MCP servers need zero API keys. Clone, run setup.sh, start searching. Skills are, as usual, plain markdown. They work in OpenCode and Claude Code automatically (I added a tiny setup script), and they'll work in anything else that supports skills. PRs welcome! Help me expand the toolkit! :) https://bit.ly/47ObeAl https://bit.ly/47ObeAl April 4, 2026 at 03:26AM

Show HN: Semantic atlas of 188 constitutions in 3D (30k articles, embeddings) I built this after noticing that existing tools for comparing constitutional law either have steep learning curves or only support keyword search. By combining Gemini embeddings with UMAP projection, you can navigate 30,828 constitutional articles from 188 countries in 3D and find conceptually related provisions even when the wording differs. Feedback welcome, especially from legal researchers or comparative law folks. Source and pipeline: github.com/joaoli13/constitutional-map-ai https://bit.ly/41cQK0z April 2, 2026 at 03:40AM

Show HN: CLI to order groceries via reverse-engineered REWE API (Haskell) https://bit.ly/4m08tlg

Show HN: CLI to order groceries via reverse-engineered REWE API (Haskell) I just had the best time learning about the REWE (German supermarket chain) API, how they use mTLS and what the workflows are. Also `mitmproxy2swagger`[1] is a great tool to create OpenAPI spec automatically. And then 2026 feels like the perfect time writing Haskell. The code is handwritten, but whenever I got stuck with the build system or was just not getting the types right, I could fall back to ask AI to unblock me. It was never that smooth before. Finally the best side projects are the ones you actually use and this one will be used for all my future grocery shopping. [1] https://bit.ly/3FHG1j9 https://bit.ly/4didRhz March 30, 2026 at 07:45AM

Show HN: WordBattle – Daily word game where AI agents compete against humans https://bit.ly/4toOUWw

Show HN: WordBattle – Daily word game where AI agents compete against humans WordBattle is a daily 6-letter word guessing game with team leaderboards. The twist: AI agents get their own accounts, play the same daily puzzle, and rank alongside human players. It's also really fun to play in teams against your family, friends and co-workers. Agents are handicapped — humans see exact letter positions (correct/present/absent), but agents only learn whether a letter exists in the word or not. No positional info. It makes the game fair while giving agents a genuine challenge. Agent accounts are visually tagged on leaderboards so humans know who they're competing against. Maybe we'll even see just teams of agents. The agent integration: - REST API with OpenAPI 3.1 spec - MCP server (JSON-RPC 2.0, no SDK dependency) - A2A discovery card at /.well-known/agent-card.json We've shipped a skill that handles everything autonomously — registration, email verification, login, playing, and reporting results. Just `npx skills add oneonefourteam/wordbattle-skill` and tell your agent to play. The game itself: one puzzle per day, six guesses, team leaderboards with Slack/Microsoft Teams webhook integration. Free, no ads. oneonefour is a one person band, hi!, so the entire product was built using Claude Code — the UI, auth, security model, deployment pipeline, everything. Deliberately chose technologies I didn't know, with agents implementing while I guided the product decisions. I'll create a full technical write up in the near future.
