GraphRAG

The frontend talks only to the backend; your API keys + pipeline URL stay server-side.

Get started

Option A · Docker Compose (one command)

cp .env.example .env        # add your API key(s)
docker compose up --build

Option B · Backend (manual)

cd backend
python -m venv .venv && source .venv/bin/activate
pip install -r requirements.txt
cp .env.example .env        # add your API key(s)
python pipeline.py ingest ./corpus
uvicorn serve:app --reload  # http://localhost:8000

Option B · Frontend (Next.js)

cd frontend
npm install
cp .env.local.example .env.local
npm run dev                 # http://localhost:3000

The downloaded README.md has the full guide — vector DB setup, API keys, and deployment to Render/Railway + Vercel.
