Self-hosted

npx sim-setup

Self-hosting

npx sim-setup is an interactive wizard that creates a small sim/ deployment directory, provisions the database, generates secrets, writes .env, connects a Chat API key, and starts the published Sim images with Docker Compose. It does not clone the repository.

Inside a cloned Sim repository, run bun run sim-setup to unlock the source-only local development and Kubernetes modes.

Reconfigure an optional capability without rerunning the full wizard:

npx sim-setup config detects the effective local-dev, Docker Compose, or current-context Helm configuration and reports configured, missing, or invalid capabilities and OAuth integrations without printing credential values. This is separate from npx sim-setup status, which reports whether installed services are running and healthy.
