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.

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!

KillSaaS is my answer to subscription software in the AI era. I'm building this because I believe small teams can use modern AI tools to create free alternatives to giants like Figma and DocuSign in weeks, not years. We're creating a platform where developers vote on which SaaS to replace, then build it together as open source. wdyt?

Hey people! I have been compiling a database of opensource alternatives and I'm super proud of it so far. It serves as a searchable directory for high-quality opensource. After tons of hours I've managed to compile a database of 1000+ opensource software. I've seen other sites which have the same premise and all the GitHub Awesome Lists, but they lack in showing if the repo is active, abandoned, experimental, buggy/unstable, has a restrictive license or corporate influence like this does. Thanks for your time, if you have any recommendations for features/additions I'd love to hear.

Hi guys, I want to share the recent project i developed. I built AlternateOSS, a directory of free, open source alternatives and competitors to popular software. Currently, i have listed 200+ tools so far and organized them carefully based on their main functionalities. I ranked them based on its category relevancy and feature completeness. Some technical details & features: - fully static site built with Astro - View Transition API for smooth navigation - Instant/static search with Astro static endpoints If you have an open source project that can be an alternative to popular software,…

Hi HN, I'm Mohammed, a technical founder who loves shipping and giving back to the community. I'm open-sourcing the full-stack engine that powers my B2B product, apflow.co. What it is: A production B2B starter with a Go backend and Next.js frontend. Both are fully Dockerized with separate containers. No Vercel. No Supabase. Deploy the whole thing on a $6 VPS, or split frontend and backend across different providers. You own the infrastructure. The problem I was solving: Every SaaS starter I evaluated had the same issue: they locked me into someone else's platform. Vercel for hosting.…
