GitPR AI

An autonomous AI agent that scans GitHub repositories for bugs, fixes them, and automatically opens Pull Requests.

Tech stack: FastAPI (backend) + React/Vite (frontend)

Setup

Backend (server/)

cd server
uv sync

Configure .env in server/:

GITHUB_CLIENT_ID=your_github_oauth_app_client_id
GITHUB_CLIENT_SECRET=your_github_oauth_app_client_secret
SESSION_SECRET_KEY=random_secret_key
APP_BASE_URL=http://localhost:8000
OPENROUTER_API_KEY=your_openrouter_api_key
OPENROUTER_MODEL=anthropic/claude-3-haiku

Run locally:

uv run uvicorn app.main:app --reload

Frontend (client/)

cd client
npm install
npm run dev

The Vite dev server proxies /api requests to the backend automatically.

Docker

Build and run both services with a single command:

docker compose up -d

The frontend is served at http://localhost:3000 and the API at http://localhost:8000.

To rebuild after code changes:

docker compose up -d --build

To stop:

docker compose down

Environment variables are read from server/.env. See .env.example for all available options.

Production (alternative)

• Frontend — deploy client/ to Vercel with VITE_API_URL set to the backend URL
• Backend — deploy server/ to Render with root directory set to server, start command uv run uvicorn app.main:app --host 0.0.0.0 --port $PORT, and env vars: APP_BASE_URL, COOKIE_SAMESITE=none, COOKIE_SECURE=true
