See any repo's health, bus factor and maintainer risk in under a minute.
Live demo: add the deployed URL here after the first deploy (see docs/DEPLOY.md).
No sign-up needed: paste owner/repo on the landing page, or open one of the pre-analyzed showcase repos. Every public report lives at /r/<owner>/<repo>.
All scores are deterministic (no LLM involved) and computed from recent commit and pull request history (default window: the last 12 months, capped at 5,000 items per stream). Every score comes with human-readable evidence lines explaining why.
| Score | What it tells you |
|---|---|
| Health (0-100) | Activity, velocity, maintenance and community signals. |
| Resilience (0-100) | How well the project survives people leaving: knowledge spread, review coverage, freshness. |
| Bus factor | How few contributors carry most of the work. Lower is riskier. |
Tiers used by badges: Excellent 80+, Good 60+, Warning 40+, Critical below 40.
Open your repo's report page and copy the Markdown from the "Add this badge" box. It looks like:
[](https://YOUR-HOST/r/OWNER/REPO)A repo that has not been analyzed shows not analyzed, never a made-up number.
Requirements: Node 20+, pnpm 9, Docker.
git clone https://github.com/voidswift/Forge-Lens.git
cd Forge-Lens
# 1. Configure environment
cp apps/web/.env.example apps/web/.env.local
# Fill in at least: Clerk keys (dashboard.clerk.com) and GITHUB_TOKEN.
# Generate DB_ENCRYPTION_KEY:
# node -e "console.log(require('crypto').randomBytes(16).toString('hex'))"
# 2. Install, start Postgres 15, apply migrations
pnpm run setup
# 3. (Optional) pre-analyze the showcase repos (needs GITHUB_TOKEN)
pnpm seed:showcase
# 4. Run the app and the Inngest dev server (two terminals)
pnpm dev
npx inngest-cli dev -u http://localhost:3000/api/inngestNotes:
- Use
pnpm run setup, notpnpm setup(the latter is a built-in pnpm command). - Port 5432 busy?
POSTGRES_PORT=5433 docker compose up -dand change the port inDATABASE_URL. - Without
OPENAI_API_KEYthe optional AI Insights page is simply hidden.
pnpm lint && pnpm typecheck && pnpm test && pnpm buildCI runs exactly these on every pull request.
