Sim is the open-source AI workspace for building, deploying and governing AI agents. Create agents visually, in Chat or in code, ground them in a synced knowledge base, connect 270+ integrations, and control access, spend and deployment from one place — on Sim Cloud or self-hosted.
Create agents by describing them in Chat, arranging blocks on a visual canvas, or writing code and CLI commands, and deploy the result without rebuilding it.
Sync and auto-update documents from Notion, Google Drive, Confluence, Slack, GitHub and SharePoint so agents ground answers in current company knowledge.
Agents read and write structured data in Sim Tables and keep files and artifacts organized in one shared store across runs.
Trace every agent run block by block with success rate, latency, execution cost and failure details for debugging and reporting.
