[Other] Show HN: Open source alternative to Perplexity Comet Hey HN, we&#x27;re a YC startup building an open-source, privacy-first alternative to Perplexity Comet.<p>No invite system unlike bunch of others – you can download it today from our website or GitHub: <a href="https:&#x2F;&#x2F;github.com&#x2F;browseros-ai&#x2F;BrowserOS">https:&#x2F;&#x2F;github.com&#x2F;browseros-ai&#x2F;BrowserOS</a><p>--- Why bother building an alternative? We believe browsers will become the new operating systems, where we offload much bunch of our work to AI agents. But these agents will have access to all your sensitive data – emails, docs, on top of your browser history. Open-source, privacy-first alternatives need to exist.<p>We&#x27;re not a search or ad company, so no weird incentives. Your data stays on your machine. <i>You can use local LLMs with Ollama</i>. We also support BYOK (bring your own keys), so no $200&#x2F;month plans.<p>Another big difference vs Perplexity Comet: our agent runs locally in your browser (not on their server). You can actually watch it click around and do stuff, which is pretty cool! Short demo here: <a href="https:&#x2F;&#x2F;bit.ly&#x2F;browserOS-demo" rel="nofollow">https:&#x2F;&#x2F;bit.ly&#x2F;browserOS-demo</a><p>--- How we built? We patch Chromium&#x27;s C++ source code with our changes, so we have the same security as Google Chrome. We also have an auto-updater for security patches and regular updates.<p>Working with Chromium&#x27;s 15M lines of C++ has been another fun adventure that I&#x27;m writing a blog post on. Cursor&#x2F;VSCode breaks at this scale, so we&#x27;re back to using grep to find stuff and make changes. Claude code works surprisingly well too.<p>Building the binary takes ~3 hours on our M4 Max MacBook.<p>--- Next? We&#x27;re just 2 people with a lot of work ahead (Firefox started with 3 hackers, history rhymes!). But we strongly believe that a privacy-first browser with local LLM support is more important than ever – since agents will have access to so much sensitive data.<p>Looking forward to any and all comments!

[Other] Show HN: Ten years of running every day, visualized Today marks ten years, 3653 consecutive days, of running at least one mile every day under the USRSA rules [1]. To celebrate, I built an interactive dashboard that turns a decade of GPX files into charts you can explore.<p>Running has truly changed my life: I&#x27;ve made lifelong friends, explored beautiful places, and more importantly invested into my own health and fitness, which I&#x27;m starting to see the positive benefits as I get older.<p>The stack is pretty simple: a NextJS app, with a Postgres database to keep all my running data, and all the stats are pre-computed and cached in Redis, so I effectively only hit the database once a day when a new run is ingested. On the fronted, I toyed with the idea of using D3 or pre-existing data viz libraries, but ended up rolling my own using SVGs directly, it gave me more control on the visualizations.<p>I used the Strava bulk export to pre-populate the database, and I&#x27;m using their webhook API to do incremental updates. I have to tap into OpenWeatherMap and OpenCageDate to enrich the running data a little bit.<p>Happy to answer anything about the stack, data pipeline, or how I stayed motivated for 10 years!<p>[1] <a href="https:&#x2F;&#x2F;www.runeveryday.com" rel="nofollow">https:&#x2F;&#x2F;www.runeveryday.com</a> Run Streak Association rules: ≥ 1 mile per day

[Other] Show HN: Typeform was too expensive so I built my own forms Hey HN,<p>I&#x27;m a solopreneur and run a web design agency.<p>I create open-source apps, but I also work as a freelancer and designer. I was accepting any new freelance project via forms on my agency website.<p>I was using Typeform, but as time went by and more people submitted forms, it got more and more expensive. That time, I thought to use Google Form, but it was way too blocky and looked very unprofessional on my agency website.<p>So I thought to build my own forms for my own usage, and it turns out it almost doubled form submissions and inquiry calls.<p>I was happy, so I thought to build it for everyone and make it open-source.<p>I added AI functionalities using Vercel AISDK. I can generate forms almost instantly using AI and also added analytics AI so that users can talk with their forms—more like talk with their analytics data.<p>I&#x27;ve been building this publicly, sharing updates on my X account (preetsuthar17)<p>I hope this product will be as helpful to you as it was for me. Would love your feedback pls<p>Preet

[Other] Show HN: MCP server for searching and downloading documents from Anna's Archive I was looking around for an MCP server that could connect Anna&#x27;s Archive to Claude Desktop, as I wanted to be able to search and download books directly through the interface.<p>I couldn&#x27;t find any public implementations, so ended up building one myself.<p>What it does?<p>- It searches Anna&#x27;s Archive by keywords. - It downloads books from search results. - It works directly in Claude Desktop through MCP.<p>Check out the repository&#x27;s README for detailed installation and configuration instructions.<p>The code is fully open source and builds run on GitHub Actions for transparency.<p>I figured I&#x27;d share, since I couldn&#x27;t be the only one wanting this functionality!
