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.

Highlights

  • Apache-2.0; the README reports 100,000+ builders and the repository currently shows 29,796 stars.
  • Self-host via npx sim-setup, which provisions the database, generates secrets, writes .env and starts published images with Docker Compose.
  • Ships native TypeSafe System One evaluation and decision provider integration, per the curated directory summary.
  • Connects 1,000+ integrations and every major LLM; the stack includes Next.js, Bun, PostgreSQL, Drizzle and Better Auth.
  • Desktop app for macOS 12+ on Apple Silicon and Intel, with local models via Ollama and vLLM.

Watch out

Apache-2.0. Self-hosting needs Node.js 20+ and Docker, with roughly 12 GB of RAM per the README's troubleshooting notes; the hosted platform at sim.ai is a paid service.
