About Sim
Sim is an open-source workspace for building, deploying and managing AI agents and workflows. It connects more than 1,000 integrations and every major LLM, builds agents visually, conversationally or in code, ingests files, knowledge bases and tables, and monitors runs, logs and schedules. It is available as the hosted sim.ai service, self-hosted with Docker through an interactive setup wizard, or as a macOS desktop app.
Sim is listed in this index written primarily in TypeScript, with 30k stars on GitHub. Its latest recorded repository push was in November 2026; that is not an ASE editorial review date.
