OrbitStats — Contributor Analytics Dashboard

A blueprint-style analytics dashboard for any public GitHub repository: weekly commit activity over the last year, language composition, and a ranked contributor leaderboard — all rendered as SVG charts with zero charting library.

Features

• Commit-frequency bar chart, 52 weeks, built from GitHub's contributor stats endpoint
• Language composition bar with percentage breakdown
• Top-8 contributor leaderboard with proportional bars
• Handles GitHub's async stats computation (202 responses) with polling and a friendly wait message
• Handles the real edge cases of a public API: unknown repos (404), rate limiting (403), and network failures, each with a clear message
• Zero dependencies — vanilla HTML, CSS, and JavaScript

Why no backend?

The GitHub REST API serves public repository and contributor-statistics data over plain HTTPS with CORS enabled, so the browser can call it directly — no server needed to proxy requests or hide a key, because none is required for this kind of read-only public data.

Rate limit: unauthenticated requests are capped at 60 per hour, per IP address, by GitHub.

Note on stats computation: very large or very old repositories can take a moment for GitHub to compute contributor stats on first request — the app polls and shows a wait message rather than failing outright. The contributor leaderboard is capped at the top 8 for legibility.

Run it locally

Clone the repo and open index.html in a browser. No build step, no npm install.

git clone https://github.com/arjayb/OrbitStats.git
cd OrbitStats
open index.html # or just double-click it

If your browser blocks fetch on the file:// protocol, serve it with any static server instead:

python3 -m http.server 8000
# then visit http://localhost:8000

Deploy to GitHub Pages

1. Push this repo to GitHub.
2. Go to Settings → Pages.
3. Under Build and deployment, set Source to Deploy from a branch, pick main and / (root).
4. Save — your app will be live at https://<your-username>.github.io/OrbitStats/ within a minute or two.

Data source

All data comes from the public GitHub REST API, including the repository, contributor-stats, and languages endpoints. No authentication, no API key, no user data is stored — every lookup is a fresh, live request.
