Hey HN, we're a YC startup building an open-source, privacy-first alternative to Perplexity Comet. No invite system unlike bunch of others – you can download it today from our website or GitHub: https://github.com/browseros-ai/BrowserOS --- 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. We're not a search or ad…

Perplexity Labs▲638We built a search engine interface on top of OpenAI GPT 3.5 and Microsoft Bing that summarizes and cites top search results in response to natural language questions. By using search results, the AI is able to reference recent news and provide citations for specific facts. Our interface offers concise answers, without having to click through links, scroll past irrelevant content, or read ads. No login is required; no personal data is collected. We believe in the power of combining the intuitive UI of web search with the intelligence of large language models. The search engine does indexing…

Hi, Piotr here I was collecting nice open-source companies for quite some time now. Mostly to take some inspiration and learn from their code. Last week, I though it would be fun to learn this Astro thing everyone's talking about. So I thought building a directory website out of this collection was pretty good idea. After 2 days of building, OpenAlternative was born. It's a community driven list of open source alternatives to proprietary software and applications. Enjoy and thank you for your support!

Hey guys, I am think of building an open-source version of Perplexity to let devs play around with it. But with all the existing tools available what features would you want? Anything specific? What is missing? Currently working on - 1. Streaming text 2. Citations sources 3. Image and file upload 4. Chat history and storage 5. Temperature and custom instructions If you are in marketing or growth can anyone help me with what to focus on while building such an app? Also here is a very first version. Probably will break and most of the buttons also don’t work, built it in 3 days using Bing and…

I got tired of collecting open source projects in my chrome bookmarks so I decided to compile a curated list of: - Recently active projects on GitHub - Mostly dev tools (but also productivity, analytics) - Projects which are "Alternative to X software" My bookmarks are finally empty:D If you have a great open source tool you use, I'd be glad to hear your suggestions. Also, any feedback is greatly appreciated.

Hey HN Community, I recently found myself knee-deep in a fascinating challenge that I think you'll find intriguing. I'm a backend developer with a penchant for Node.js and SQL, and I've been wrestling with a problem that's both technically intricate and surprisingly common in the world of open-source development. The issue at hand? Duplicate GitHub issues. They're like weeds in a garden – you turn your back for a second, and suddenly they're everywhere, choking out the valuable discussions and dragging down productivity. So, I set out to build a bot. Not just any bot, mind you, but a Probot…

Hi HN, Martin, Nils, and Jannes here. We are building Legit, an open source version control and collaboration layer for AI agents and AI native applications. You can find the repo here https://github.com/Legit-Control/monorepo and the website here https://legitcontrol.com Over the last years, we worked on multiple developer tools and AI driven products. As soon as we started letting agents modify real files and business critical data, one problem kept showing up. We could not reliably answer what changed, why it changed, or how to safely undo it. Today, most AI…
