There's a cloud version at sim.ai, an open-source self-hosted deployment, and a macOS desktop app (12+, Apple Silicon and Intel) that can point at your own self-hosted instance.

The wizard creates a sim/ directory, provisions the database, generates secrets, writes .env, and starts everything with Docker Compose — no repo clone needed.

Major LLM providers are supported, and self-hosted installs can also run local models via Ollama and vLLM.

The wizard connects a Chat API key for you (just sign in when it opens the browser); keys can be viewed, created, or revoked at sim.ai/selfhost/settings/chat-keys.

Agents can also ingest files, knowledge bases, and structured table data as context.

Agents can also ingest files, knowledge bases, and structured table data as context.Is building an agent drag-and-drop or coding?Your choice: the README lists three ways — visually, conversationally, or with code. The flow editor underneath is ReactFlow, so visual building happens on a node canvas.

All of it is reachable from the browser or the Mac desktop app.
