How this ranking works

Score = merge rate × reply speed. The merge rate is the share of pull requests from outside contributors (anyone who is not an owner, member or collaborator of the project, bots excluded) merged in the last 30 days, smoothed as (merged + 1) ÷ (sent + 2) so a few lucky merges do not outrank a long record. The reply speed is 1 ÷ (1 + the median number of days before a pull request gets its first reply from someone other than its author, or is merged). Bot comments do not count as replies.

Listed: projects with at least 10 outside pull requests in that window, at least one open beginner issue, at least 10 stars, a push in the last 180 days, not archived, and measured in the last 30 days.
