Sim is an open-source platform for building and deploying AI agent workflows using visual canvas design and natural language generation via Copilot.
It supports integration with 1,000+ services and LLMs, vector database knowledge stores, and can be self-hosted via Docker, npm, or manual setup with PostgreSQL and Bun. The platform enables teams to orchestrate agentic workflows with background job processing through Trigger.dev and remote code execution capabilities.
