Flexible API mocking for unit, integration and performance testing

WireMock is a tool for creating mock APIs. Build predictable development environments, isolate yourself from flakey 3rd party APIs and prototype APIs that don't exist yet.

Open Source

The core WireMock engine. Embed in your unit tests, or run as a standalone server anywhere there's Java or Docker available

Studio

WireMock Studio is tool built on top of the core WireMock engine, bringing a full web UI, management of multiple mock APIs and support for OpenAPI and Postman.

It can run on your laptop, in Docker or in your test environment, and has exactly the same data format as the underlying WireMock engine, so it's easy to reuse mock APIs or test code you've already created.
