Mockae

About Mockae

Mockae is an open-source tool for mocking REST APIs, with source code available for download on GitHub. It uses Lua code to define custom rules that determine the HTTP status codes, headers, and response bodies returned for incoming requests, based on the request's URL, headers, and payload. Rules execute before a response is sent and can override the default output.

The service also provides a free, read-only public API for testing, hosted at api.mockae.com, with fake resource endpoints for products, carts, users, and coupons, plus a status endpoint for simulating specific HTTP response codes.

Mockae is aimed at developers who need mock APIs for testing and prototyping.
