Everything you need to understand repo health
Health Score
0–100 composite score across response time, PR velocity, triage health, and community growth — with a letter grade A through F.
Issue Metrics
Median first-response and close times, closed-within-7-days %, stale issue %, and label breakdown.
PR Velocity
Median review latency and merge time, merge rate, average review rounds, and stale PR count.
Contributors
Total contributor count, new contributors in the last 30 days, and a top-10 leaderboard.
Trend Charts
Health score, stars / forks, open issues / PRs, and new contributors charted over time.
6-hour Cache
Results are cached for 6 hours — repeated lookups of the same repo return instantly without counting against the cap.
