SaaSSubscription · Community free plan with 1,000 credits, 5GB storage, and 1 personal workspace; Pro $25/mo with 6,000 credits, 50GB storage, up to 3 personal workspaces; Max $100/mo with 25,000 credits, 500GB storage, up to 10 personal workspaces; Enterprise pricing custom with self-hosting and dedicated support.

Sim is an open-source AI workspace that helps teams build, deploy, and manage AI agents. It connects 1,000+ integrations and major LLMs, offering visual, conversational, or programmatic ways to create agents that automate real work.

Sim provides an AI workspace with four core components: Mothership (natural-language command center to control the workspace), Tables (built-in database for data wiring in workflows), Files (shared document store), and Logs (execution traces with inputs, outputs, cost, and duration). Users can build agents visually, via conversational control, or through an API, reuse 11 pre-built workflow templates, connect real integrations and LLMs, and deploy agents that run in a collaborative, multi-user environment with real-time features. The platform supports self-hosting, SOC2 compliance, and enterprise-style capabilities such as SSO/SCIM and dedicated support in its pricing tiers.

Who it’s for: Teams and organizations building and deploying AI agents who need integrations, collaboration, and governance (from startups to Fortune 500).

The fastest way to build AI agent workflows for production

Sim Studio provides an open-source, Figma-like interface to design, test, and deploy AI agent workflows. It lets users drag-and-drop LLMs and tools (Slack, Gmail, etc.), build agents, and deploy workflows as APIs or chat services, with visual iteration and support for hosted/local models and scheduled or webhook-triggered runs.
