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 everyone, A couple years ago, I got into programming and fell down the rabbit hole of open-source software. I started realizing a lot of the commercial software I used had open-source alternatives. In 2020, those alternatives were good but not perfect replacements. With LLMs entering the scene, there are even more open-source alternatives now and they're narrowing the gap between proprietary options. LLMs also got me thinking: will people continue using proprietary or opensource applications in the future when they can build their own personal application tailored specifically for their…

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.

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.
