Explore over 1,284 open-source tools organized into 41 different categories. Filter by language, license type, platform, and even country of origin. Created since other websites either had a poor UI with thousands of tools or a good UI with 500-800 tools but nothing in between. OSS Discovery has both! Absolutely no paid listings. Absolutely no spam. Only useful open-source tools.

I’m Ayush – a 19-year-old computer science student from India, building in the open.

OSS Discovery was created out of frustration. Every time I wanted to discover some open source tools, I’d be redirected to alternativeto.net(with paid tools mixed), Google blogs published in 2019 or lists on GitHub.

Directories with huge library have an ugly UI. Directories with great UI have 500-800 tools max.

There wasn’t any that had it all. So, I created it.

2-3 weeks. By myself. Without any team and funds. Only determination and lack of sleep.

1,284 curated open source tools, 41 categories, 60+ countries. Filterable by programming language, licenses, platforms, and even countries of origins. No paid listings. No spam.

But wait, there’s more – AI-based discovery, stacks and additional categories are on the way.

Feedback would be much appreciated. Which tools are missing? What categories do you think I should cover?

Bit of a wild launch day — OSS Discovery got so much traffic from the dev community before this listing even went live that Vercel and Supabase both hit their free tier limits simultaneously.
