Is Saturn App really free?

Yes. The desktop App and its runtime are open source under the MIT license. There is no paid tier, no usage cap, and no telemetry.

Pro gives a personal account access to the Saturn MCP gateway: connect MCP servers, build tool sets, write policies, review approvals, and read the audit trail. Pro is a single-user plan and cannot invite members.

What is the difference between Personal and Organization?

Free and Pro are personal accounts that act as one user. Enterprise is an organization: it has members, roles, custom permissions, shared team agents, and MCP server mapping per employee.

How is Enterprise priced?

Enterprise pricing is coming soon. Book a demo and we will follow up when the plan opens.
