Open-source repositories

All recently observed repositories in our captured sample, ranked by their latest total GitHub stars. Recomputed after imports; not a paid ranking or a complete copy of GitHub.

Snapshot: 2026-10-31T18:43:23.065Z. Rankings use this list’s declared public metric; missing values sort last, ties use record ID, and Trending retains source order.
