A workspace to build, deploy and manage AI agents and workflows. Quickstart Cloud-hosted: sim.ai Self-hosted npx simstudio Open http://localhost:3000 Docker must be installed and running. Use -p, --port <port> to run Sim on a different port, or --no-pull to skip pulling the latest Docker images. 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, knowledge, and scheduled tasks all live in the same workspace. Tables — a database, built in Files — one store for your team and every agent Knowledge — your agents' memory Scheduled tasks — runs on your schedule Self-hosting Docker Compose git clone https://github.com/simstudioai/sim.git && cd sim docker compose -f docker-compose.prod.yml up -d Open http://localhost:3000 Sim also supports local models via Ollama and vLLM. See the Docker self-hosting docs for setup details. Manual Setup Requirements: Bun, Node.js v20+, PostgreSQL 12+ with pgvector Clone and install: git clone https://github.com/simstudioai/sim.git cd sim bun install bun run prepare # Set up pre-commit hooks Set up PostgreSQL with pgvector: docker run --name simstudio-db -e POSTGRES_PASSWORD=your_password -e POSTGRES_DB=simstudio -p 5432:5432 -d pgvector/pgvector:pg17 Or install manually via the pgvector guide. Configure environment: cp apps/sim/.env.example apps/sim/.env # Create your secrets perl -i -pe "s/your_encryption_key/$(openssl rand -hex 32)/" apps/sim/.env perl -i -pe "s/your_internal_api_secret/$(openssl rand -hex 32)/" apps/sim/.env perl -i -pe "s/your_api_encryption_key/$(openssl rand -hex 32)/" apps/sim/.env # DB configs for migration cp packages/db/.env.example packages/db/.env # Edit both .env files to set DATABASE_URL="postgresql://postgres:your_password@localhost:5432/simstudio" Run migrations: cd packages/db && bun run db:migrate Start development servers: bun run dev:full # Starts Next.js app and realtime socket server Or run separately: bun run dev (Next.js) and cd apps/sim && bun run dev:sockets (realtime). Chat API Keys Chat is a Sim-managed service. To use Chat on a self-hosted instance: Go to https://sim.ai → Settings → Chat keys and generate a Chat API key Set COPILOT_API_KEY environment variable in your self-hosted apps/sim/.env file to that value Environment Variables See the environment variables reference for the full list, or apps/sim/.env.example for defaults.
