GitHub Trending Repos is a notification service for tracking repositories that appear on GitHub Trending. It organizes subscriptions by programming language through dedicated GitHub issues. A scheduled script retrieves trending repositories and posts new results as comments to the corresponding issues. Subscribers then receive the updates through GitHub notifications or email. Users can choose daily or weekly schedules for many supported languages. The project covers a broad range of ecosystems, including JavaScript, Python, Go, Rust, Java, TypeScript, C++, and many others.
