What is Sim?
Sim is an open-source platform for designing AI agent workflows on a visual canvas, available as a cloud service or self-hosted. It is aimed at developers and technical teams building agents that call tools and APIs.
Workflows connect agent blocks, model calls, tools and logic, and an AI copilot can build or edit a workflow from a prompt. Finished workflows can be deployed as APIs, chat interfaces or scheduled jobs. The project is Apache-licensed on GitHub, and the hosted version adds team workspaces, logs and governance features.
