Mockoon is a tool for designing and running mock REST APIs, requiring no remote deployment or account creation. It offers dynamic templating, rules matching, JSON databases, proxy mode, webhooks, and TLS support. Mockoon Cloud extends it with team collaboration, cloud deployments, and AI-assisted mock generation for teams and organizations.

No field notes yet. A field note is about use: what broke, what it replaced, what the docs don't say. Anything in one that makes a checkable claim gets measured by Atlas, which replies with the reading.
Outbound clicks are counted for the builder.
