Discover the most popular and fastest-growing open source projects, organized by programming language. Rankings powered by real-time analysis of 10 billion+ GitHub events.
GitHub changed how its public events feed is paginated, and our ingestion read only the first slice, so star, pull request and issue events since mid-2025 were badly under-captured. Rankings that depend on those counts would be misleading, so we pause them instead of publishing numbers we know are wrong. History before May 2025, repository totals synced directly from GitHub, and commit activity are unaffected.
