Start the cognee server locally

From an installed cognee (no Docker)

cognee-cli -ui

launches the full local stack: FastAPI backend on http://localhost:8000 and the UI on http://localhost:3000. Needs LLM_API_KEY in the environment or .env. The interactive API reference is at http://localhost:8000/docs, health at /health.

For API-only serving via Docker instead, use the cognee-docker skill (the prebuilt cognee/cognee:main image or docker compose up from the repo).
