GitRacer
Race up to 12 public GitHub contribution histories on one shareable graph.
See the saved races · MIT license
GitRacer is now a static site. Every race page is prerendered from a saved snapshot
(src/data/snapshot.json, taken 27 Oct 2026). The backend that fetched new profiles
from GitHub is offline, so building a new lineup, refreshing, or switching periods
shows a short notice instead.
Features
- Permanent race URLs such as
/levelsio+marclou for every saved race
- Battle mode and cumulative graph mode
- Contribution totals, active days, streaks, and leader margins
- Responsive light, dark, and system themes
- No analytics, no cookies
