ContribScope

Visualize the contribution breakdown of any public GitHub repository — no backend required.

Features

• Doughnut chart — top 10 contributors + "Others" slice
• Sorted list — all contributors from most to least, with commit count and percentage bar
• User search — type a username to highlight and jump to their entry
• Stats bar — total commits, contributor count, top contributor name and share
• Pagination — fetches all pages from the GitHub API (handles repos with 100+ contributors)
• Token support — paste a personal access token to raise the rate limit from 60 to 5000 req/h

Usage

Open index.html in any browser — no build step, no server needed.

1. Enter a repo in owner/repo format (or paste the full GitHub URL)
2. Optionally add a GitHub personal access token (read-only, no scopes needed)
3. Click Analyze
4. Use the search box to look up a specific contributor

GitHub API rate limits

Mode	Limit
Unauthenticated	60 req/h
With token	5 000 req/h

For repositories with many contributors, providing a token is recommended.

Notes

• "Contributions" = commit count as reported by the GitHub API (/repos/{owner}/{repo}/contributors)
• Anonymous commits and bots that have a GitHub account are included
• Forked commits are not counted by GitHub's API
