A workspace to build, deploy and manage AI agents and workflows.

Quickstart

Cloud-hosted: sim.ai

Self-hosted

npx @sim/setup

Open http://localhost:3000

Capabilities

• Connect 1,000+ integrations and every major LLM
• Add Slack, Notion, HubSpot, Salesforce, databases, and more
• Build agents visually, conversationally, or with code
• Ingest files, knowledge bases, and structured table data
• Monitor runs, logs, schedules, and workflow activity

One workspace, every surface

Chat and workflows are just the start — tables, files, and knowledge all live in the same workspace.

Tables — a database, built in	Files — one store for your team and every agent
Knowledge — your agents' memory

Self-hosting

Requirements: Node.js 20+ and Docker.

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.

When it finishes, open http://localhost:3000.

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
npx @sim/setup add email
npx @sim/setup add storage
npx @sim/setup add sandbox
npx @sim/setup add jobs
npx @sim/setup add cache
npx @sim/setup add knowledge
npx @sim/setup add llm
npx @sim/setup add integration slack

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.

Manage your install from its directory:

npx @sim/setup start | stop | restart   # bring your install up / down / cycle
npx @sim/setup update                   # pull and apply Compose images
npx @sim/setup status                   # what's installed and healthy
npx @sim/setup logs                     # follow logs
npx @sim/setup doctor                   # diagnose configuration problems
npx @sim/setup down                     # remove containers (data kept)
npx @sim/setup reset                    # archive .env and wipe managed data

The setup package detects how you're running and acts accordingly. Use --dir <path> to create or manage a deployment somewhere other than ./sim.

Sim also supports local models via Ollama and vLLM. See the self-hosting docs for details.

Chat API Keys

Chat is a Sim-managed service. npx @sim/setup connects a Chat API key for you — sign in when it opens your browser and the key is stored automatically. To view, create, or revoke keys later, go to sim.ai/selfhost/settings/chat-keys.

Environment Variables

See the environment variables reference for the full list, or apps/sim/.env.example for defaults.
