May 15, 2026 - May 21, 2026

The ten repositories that gained the most stars on GitHub in the week of May 15, 2026 - May 21, 2026, counted from GitHub's public event log. A star is a bookmark, not an endorsement: the commit counts and flags below show which ones people are actually building.

Partial data. GitHub's public event log is missing most events on May 15, 2026, May 18, 2026, May 19, 2026, May 20, 2026, May 21, 2026. Counts for this week are minimums, and a repo whose surge fell on those days may be ranked too low.
