What it is

Sim is a web workspace where you assemble AI agents and automated workflows on a visual canvas, through chat, or in code, wiring them to hundreds of integrations such as Slack, Notion, and Salesforce and to the major LLM providers. It also includes built-in tables, file storage, and knowledge bases that agents can search, plus logs, schedules, and run monitoring. Teams can use the hosted service or deploy it on their own servers with Docker Compose or Kubernetes, and a macOS desktop app and MCP server are available for working with it from other tools.
