Show HN: Saccade – Live semantic browser truth for AI agents https://bit.ly/3SDsfsO

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: 500,000+ AOL Instant Messenger Buddy Icons All at Once https://bit.ly/4gyIGhN

Show HN: 500,000+ AOL Instant Messenger Buddy Icons All at Once I needed a couple of AOL Instant Messenger buddy icons for a project, and then that turned into a project and before you know it I was trying to scrape every single buddy icon off the internet. I have slightly over 500,000 of them live, browseable, and downloadable with a single click on my new totally non-commercial project site buddyiconarchive.com I think that I am perhaps 20% of the way to my goal of having a "complete" collection of all the buddy icons that ever appeared on the internet, a rough estimate based on the counts advertised by various period aggregators. I am looking to trade icons with someone who maybe has an entire backup of iconator.com or other large buddy icon sharing site. My goal would be to add them to the archive and make them widely available. These sites, it turns out, are not completely archived in Wayback Machine, or at least it would seem.

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 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: 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!

Show HN: Classifier and browser extension to detect rule violating HN comments I love HN, but lately I have been sick of reading the same dismissive criticisms over and over again. 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 https://bit.ly/3RQ70DN

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: Decant – Understand how you spend tokens Hey HN - there are lots of tools to understand how many tokens you use and how much it costs, but we haven't found any that tell you where those tokens are going! Decant helps you understand what you are spending tokens on (context gathering, planning, code, chat, etc), so you can optimize it. https://bit.ly/4fTRAYh August 12, 2026 at 10:56PM

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: Kernelspace- interactive course on systems programming for LLM Serving https://bit.ly/4qeOQbB

Show HN: Kernelspace- interactive course on systems programming for LLM Serving Hi HN, *I* built kernelspace - a free and interactive course that takes a backend engineer (like me) with java/python experience to the systems level required to work on LLM serving at scale. (Mostly an attempt for me to understand what everyone's talking about lately and also an attempt at staying up to date to current tech - career wise). It has: 1. 68 Lessons across 9 tracks, with a rust-from-zero ramp. 2. 8 rust labs - BPE tokenizer, KV block manager, radix cache, batching scheduler, a toy executor 3. 9 simulators running in browser (wasm) - roofline model, KV cache pressure, continuous batching dynamics 4. Fleet week - a simulated prod serving fleet All progresss is local - there is no server (it's served from github pages, repo here https://bit.ly/4woWdyr ) Feedback appreciated, and contributions welcome. I want to make this a really good course for me (and everyone else like me). * (OK, I had sol and kimi on it for most part) https://bit.ly/4woWdOX August 12, 2026 at 02:20AM

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? https://bit.ly/4w5Fi3L

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 https://bit.ly/4wwxB7J

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
