Beyond GitHub Stars

Stars measure popularity. C-Rank measures active maintainers.

A repository with 40,000 stars might have unanswered PRs from months ago. When you pick projects by stars alone, you often run into backlogged, exhausted teams. GetMerged checks whether maintainers are actually reviewing and merging community pull requests today.
