About Mockerito
Mockerito lets developers build mock APIs without a server. You create custom REST endpoints, define the exact JSON payloads they return, simulate errors on demand and get a live API URL protected by API key authentication, so frontend work, tests and CI can proceed without waiting on a real backend or a third-party API.
The site lists common uses: designing an API contract before the backend exists, replacing flaky third-party APIs, powering developer portals and docs so users can try live requests, mocking APIs in CI/CD pipelines, running integration and end-to-end tests against consistent data, and letting frontend and backend teams work in parallel. You can start building for free.
