Deployment

Prerequisites

1. Node.js 22+ (matches this repo's engines field)
2. GitHub Personal Access Token (PAT) — required. Set GITHUB_PAT as a Worker secret. Scope at GitHub token settings: public stats need read:user; private stats need repo + read:user (see Important Notes).

Deploy to Cloudflare Workers

1. Fork this repository
2. Install dependencies: pnpm install (install pnpm with npm install -g pnpm if needed)
3. Configure: node scripts/generate-wrangler-config.js — then pnpm wrangler secret put GITHUB_PAT for production
4. Deploy: pnpm run deploy — in Workers Builds, use pnpm run deploy (not bare wrangler). Set GITHUB_PAT; optional GitHub Actions secrets: CLOUDFLARE_API_TOKEN, CLOUDFLARE_ACCOUNT_ID
5. Use https://YOUR-INSTANCE.WORKERS.DEV in your README embed URLs

Environment Variables

| Variable | Description | | --------------- | ----------------------------------------------------------- | | GITHUB_PAT | GitHub PAT (required); add GITHUB_PAT_2, … for more quota | | WHITELIST | Comma-separated allowed usernames | | CACHE_SECONDS | Default cache duration in seconds (0 disables) |

Full list: API.md — Environment Variables.

[!WARNING] Redeploy after changing environment variables.

[!IMPORTANT] For internet-reachable instances, set WHITELIST to intended usernames. Unset WHITELIST lets any username consume your GitHub quota. If you expose /api/gist, set GIST_WHITELIST to allowed gist IDs.

Use Sync Fork to pull upstream changes; redeploy and re-check secrets after syncing.

Configuration

Aligning Cards Side by Side

[![YOUR_USERNAME's GitHub stats](https://YOUR-INSTANCE.WORKERS.DEV/api?username=YOUR_USERNAME)](https://github.com/YOUR_USERNAME)
[![YOUR_USERNAME's top languages](https://YOUR-INSTANCE.WORKERS.DEV/api/top-langs?username=YOUR_USERNAME&layout=compact)](https://github.com/YOUR_USERNAME)

Locales

Set locale= on any card URL (e.g. &locale=es). Supported codes: API.md — Supported Locales.

Caching

Each card type has default cache durations and per-card min/max clamps for cache_seconds; override globally with CACHE_SECONDS. Details: API.md — Cache Durations.

API Documentation

Full reference: API.md, hosted docs, or openapi.yaml.

Support

If something is not working:

• Confirm your Workers URL loads in a browser (see Quick Start)
• Check PAT scopes and private-stats caveats in Important Notes and Deployment
• For WakaTime cards, confirm profile visibility under WakaTime Card
• Open an issue with the failing URL (redact secrets)

When things go wrong

Card endpoints return error SVGs (not JSON) for most failures:

| What you see | Likely cause | | ---------------------------------- | ----------------------------------------------------------------------------- | | Missing username / parameter error | username (or repo, id) not in the URL | | User not found | GitHub username typo or organization name used as username | | Rate limit / downtime message | GitHub API quota exhausted — add GITHUB_PAT_2, tighten WHITELIST, or wait | | No tokens / PAT message | GITHUB_PAT secret not set on the Worker | | WakaTime user not found | WakaTime profile or visibility settings (see WakaTime Card) |

Full error shapes: API.md — Error Handling.

Contributing

Contributions welcome — star the repo, open issues, or send PRs.

Important Notes

[!IMPORTANT] This fork is self-host-only — deploy your own Cloudflare Workers instance; there is no shared public demo URL in this repo. The GitHub API allows 5k requests per hour per PAT. Caching reduces repeat GitHub API hits for the same card URL; it does not guarantee staying under the limit when many usernames are requested, caches expire, or CACHE_SECONDS is 0. Set WHITELIST to the usernames you intend to serve, and add GITHUB_PAT_2 (and further) tokens if you need more quota.

[!WARNING] By default, cards only show statistics from public repositories. To include private repository statistics, deploy your own instance with a GitHub Personal Access Token that belongs to the same user as username. Private-repo aggregates rendered this way are still served on the public card URL — treat that as intentional disclosure, restrict the instance with WHITELIST, and do not embed the URL where those totals should stay private. Organization or SSO-restricted private repos may remain invisible even with a PAT.
