Explain in plain English what you're building and get the best matching GitHub repositories.

awesome-repositories.com helps you find the right open-source project on GitHub. Tell our AI search what you want to build, in plain English, and it ranks thousands of curated repositories by how well they fit. Every project is continuously monitored, sorted into clear categories, and upvoted by other developers. Browse the picks below, or search to start.

Common questions

What is awesome-repositories.com?

A curated directory of open-source GitHub repositories that you search in plain English. Describe what you are building and an AI ranks thousands of vetted projects by how well they fit, each with a short note on why it matched.

How is it different from GitHub search?

GitHub search matches the keywords you type. Here you describe the problem in plain English and the AI matches on intent, so a project that solves your need shows up even when it never uses your exact words.

How do I find the best open-source repository for a task?

Type what you want to build, for example a self-hosted status page that pings my services and alerts me on Discord. You get matching repositories ranked by fit rather than by raw star count.

Are the repositories curated or just scraped?

Curated, not a raw scrape. An AI analyses each project, sorts it into a category, and ranks it by relevance under rules we tune and review, and low-signal or duplicate entries are pruned.

Is it free to use?

Yes. Searching and browsing the directory are free.
