It connects 1,000+ integrations and every major large language model (LLM), letting teams create agents visually, conversationally, or with code and govern access, spend, and deployment from one workspace on their own infrastructure.

First-install notes

  • Self-Hosting Setup Requires Node.js 20+ and Docker. Run npx sim-setup to create the deployment directory, provision the database, generate secrets, and start the published Sim images with Docker Compose. The app server also needs the simstudio-db (PostgreSQL with pgvector), simstudio-realtime (WebSocket), and simstudio-valkey (session storage) companion services. source

Common questions

How do I self-host Sim Studio from scratch?

Run npx sim-setup to create a small deployment directory, provision the database, generate secrets, write .env, connect a Chat API key, and start the published Sim images with Docker Compose.

How can I check configuration problems separately from service health?

npx sim-setup config reports configured, missing, or invalid capabilities and OAuth integrations without printing credential values. npx sim-setup status reports whether installed services are running and healthy.

Is a self-hosted login required to use Sim Studio?

A GitHub issue reports that the program requires a self-hosted login and that the docs did not explain how to satisfy or bypass it.
