Yes — the docker-compose and Helm chart run the full stack (app + ClickHouse + Postgres + Redis). Many enterprises use the self-hosted version to keep prompts and traces inside their own VPC.
You create versioned prompts in the Langfuse UI and label them (`production`, `staging`). Your app calls `langfuse.get_prompt('name', label='production')`, which returns the current version — swapping a prompt requires no redeploy.
