Basic analytics help us catch bugs and improve tools -- disable anytime by rebuilding with `SNAPOTTER_ANALYTICS=off` ([Here's how to do it](https://docs.snapotter.com/guide/deployment.html#analytics)) ## Quick Start SnapOtter runs as a small Docker Compose stack (app + Postgres 17 + Redis 8). Save this as `compose.yaml`: ```yaml services: snapotter: image: snapotter/snapotter:latest ports: ["1349:1349"] environment: DATABASE_URL: postgres://snapotter:snapotter@postgres:5432/snapotter REDIS_URL: redis://redis:6379 volumes: - snapotter-data:/data depends_on: [postgres, redis] restart: unless-stopped postgres: image: postgres:17-alpine environment: POSTGRES_USER: snapotter POSTGRES_PASSWORD: snapotter POSTGRES_DB: snapotter volumes: ["snapotter-pgdata:/var/lib/postgresql/data"] restart: unless-stopped redis: image: redis:8-alpine volumes: ["snapotter-redisdata:/data"] restart: unless-stopped volumes: snapotter-data: snapotter-pgdata: snapotter-redisdata: ``` Then start the stack: ```bash docker compose up -d ```
