About wiremock
WireMock is an open source tool for mocking HTTP services, started in 2011 as a Java library by Tom Akehurst and now spanning multiple programming languages and technology stacks. It lives in the Java ecosystem, is licensed under Apache 2.0, and is published at wiremock.org. The project can run as a library or client wrapper in many languages, or as a standalone server, and it supports several approaches for creating mock APIs: in code, via its REST API, as JSON files, and by recording HTTP traffic proxied to another destination.
