How to get started?

Quick Start with Docker 🐳

[!TIP] For production deployments, use the full Docker Compose setup which offers more control and scalability.

Linux/macOS:

docker run -d -p 3000:3000 -p 8000:8000 \
  -v surfsense-data:/data \
  --name surfsense \
  --restart unless-stopped \
  ghcr.io/modsetter/surfsense:latest

Windows (PowerShell):

docker run -d -p 3000:3000 -p 8000:8000 `
  -v surfsense-data:/data `
  --name surfsense `
  --restart unless-stopped `
  ghcr.io/modsetter/surfsense:latest

With Custom Configuration:

You can pass any environment variable using -e flags:

docker run -d -p 3000:3000 -p 8000:8000 \
  -v surfsense-data:/data \
  -e EMBEDDING_MODEL=openai://text-embedding-ada-002 \
  -e OPENAI_API_KEY=your_openai_api_key \
  -e AUTH_TYPE=GOOGLE \
  -e GOOGLE_OAUTH_CLIENT_ID=your_google_client_id \
  -e GOOGLE_OAUTH_CLIENT_SECRET=your_google_client_secret \
  -e ETL_SERVICE=LLAMACLOUD \
  -e LLAMA_CLOUD_API_KEY=your_llama_cloud_key \
  --name surfsense \
  --restart unless-stopped \
  ghcr.io/modsetter/surfsense:latest

[!NOTE]

If deploying behind a reverse proxy with HTTPS, add -e BACKEND_URL=https://api.yourdomain.com

After starting, access SurfSense at:

Frontend: http://localhost:3000
Backend API: http://localhost:8000
API Docs: http://localhost:8000/docs

Useful Commands:

docker logs -f surfsense      # View logs
docker stop surfsense         # Stop
docker start surfsense        # Start
docker rm surfsense           # Remove (data preserved in volume)

Installation Options
