Sim
Open-source workspace to build, deploy, and govern AI agents
Visit sim.ai ↗What is Sim?
Sim is an open-source platform where teams build, deploy, and manage AI agents with centralized control over access, spend, data, and performance. It supports 1,000+ integrations and every major LLM, with options to build agents visually, conversationally, or with code. The workspace includes tables, files, knowledge bases, and logs all in one place, available in the browser or on desktop.
Users can self-host Sim in their own cloud using Docker and Node.js, or use the cloud-hosted version. The platform includes workflow versioning, rollbacks, native RAG capabilities, and detailed observability through trace spans. According to the maker, it was built using Claude Code and Cursor as AI coding tools.
