01
Define the contract
Model resources and response shapes with familiar TypeScript interfaces and type aliases.
ABOUT MOCK API STUDIO
A cloud control plane for mock APIs that run locally.
Mock API Studio helps developers and QA teams define realistic API contracts before a production backend is ready. Project configuration lives in the dashboard; the generated server and records run on your machine.
How it works
02
Configure behavior
Control CRUD operations, generated data, auth, pagination, latency, errors, and relationships.
03
Run it locally
Synchronize the project and serve the generated API from a local runtime on your machine.
Why local-first?
A local runtime stays fast during development, keeps generated records on the developer machine, and remains available after project configuration has been synchronized. Teams still get a shared place to manage contracts and behavior.
Built for practical API work
The goal is straightforward: give frontend developers, backend developers, QA engineers, freelancers, agencies, and product teams a controllable backend substitute without maintaining a custom mock server.
