Comparison between Mockoon and WireMock API mocking
Discover the differences between WireMock API mocking and Mockoon's desktop application and CLI mocking features
WireMock is a mocking or stubbing Java library. It enables developers to create mock REST APIs programmatically in their Java applications. Coupled with WireMock Studio, it allows to intercept and proxy requests, or create mock endpoints from the entering requests. The mock API endpoints can account for realistic use cases thanks to a request matching system and a templating language similar to Mockoon's one. WireMock's stubs can also be deployed online using their cloud offering, MockLab.
While Mockoon provides a similar mocking experience, it has a different approach as it offers an offline, privacy-friendly desktop application. Accompanied by a CLI that allows you to deploy your REST mocks anywhere, it gives the power needed to automate your API development and testing. Mockoon is easy to use and has no learning curve. You can easily start using it and create your first mock API in under a minute. From a powerful templating system to generate dynamic and realistic mock data to a proxy mode to partially mock API endpoints, Mockoon takes API mocking to the next level. It also offers many customization options: status codes, dynamic headers, rules system, etc.
