Quickstart
Cloud-hosted: sim.ai
Self-hosted: NPM Package
npx simstudio→ http://localhost:3000
#### Note Docker must be installed and running on your machine.
#### Options
| Flag | Description |
|---|---|
-p, --port | Port to run Sim on (default 3000) |
--no-pull | Skip pulling latest Docker images |
Self-hosted: Docker Compose
git clone https://github.com/simstudioai/sim.git && cd sim
docker compose -f docker-compose.prod.yml up -d#### Background worker note
The Docker Compose stack starts a dedicated worker container by default. If REDIS_URL is not configured, the worker will start, log that it is idle, and do no queue processing. This is expected. Queue-backed API, webhook, and schedule execution requires Redis; installs without Redis continue to use the inline execution path.
Sim also supports local models via Ollama and vLLM — see the Docker self-hosting docs for setup details.
Self-hosted: Manual Setup
Requirements: Bun, Node.js v20+, PostgreSQL 12+ with pgvector
- 1.Clone and install:

- 1.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"- 1.Run migrations:
cd packages/db && bun run db:migrate- 1.Start development servers:
Don't lose this
Three weeks from now, you'll want Sim again. Will you remember where to find it?
Save it to your library and the next time you need Sim, it’s one tap away — from any AI app you use. Group it into a bench with the rest of the team for that kind of task and you can pull the whole stack at once.
⚡ Pro tip for geeks: add a-gnt 🤵🏻♂️ as a custom connector in Claude or a custom GPT in ChatGPT — one click and your library is right there in the chat. Or, if you’re in an editor, install the a-gnt MCP server and say “use my [bench name]” in Claude Code, Cursor, VS Code, or Windsurf.
