WireMock Open Source is a free API mocking and service virtualization library for simulating HTTP-based services in test environments.
WireMock Open Source enables development and testing teams to create stub HTTP services that mimic the behavior of real APIs, supporting configurable request matching, response templating, and stateful scenario simulation. It integrates natively with JVM testing frameworks such as JUnit and supports both standalone server and programmatic modes.
The open-source library is used as a direct alternative to live service dependencies in integration and contract testing pipelines, making it a competitor to automated service virtualization tools that generate mocks from recorded production traffic.
