About Sim Studio
Sim is an open-source workspace for building, deploying and managing AI agents. Teams can assemble agent workflows on a visual canvas, describe them conversationally, or write them in code, then connect them to major language models and a large catalog of third-party apps. The company, formerly known as Sim Studio, came out of Y Combinator's Spring 2025 batch and is based in San Francisco.
Beyond the workflow editor, the platform includes a knowledge base that syncs company documents, tables for structured data that agents can read and update, shared file storage, and block-by-block execution logs with cost tracking. Workflows can be started by schedules, webhooks, RSS feeds, table events or API calls, and external services can be added through the Model Context Protocol.
Sim is released under the Apache 2.0 license and can be self-hosted with Docker or Kubernetes, including fully offline setups using local models through Ollama or vLLM. The hosted service offers a free tier, per-user paid plans, and an enterprise plan with SSO, SCIM, permission groups, spend limits and audit records.
