WireMock is a tool for building mock APIs. Create stable development environments, isolate yourself from flakey 3rd parties and simulate APIs that don't exist yet.
Learn WireMock and contribute to open source
This October we participate in Hacktoberfest - a global open source hack fest. We invite you to join us, regardless of your profile and technology stack.
Adopt WireMock in your projects, contribute new features and fixes, improve docs, create new demos and artwork, etc.
WireMock frees you from dependency on unstable APIs and allows you to develop with confidence. It's easy to launch a mock API server and simulate a host of real-world scenarios and APIs - including REST, SOAP, OAuth2 and more.
