Comparison between Mockoon and MockLab API mocking
Discover the differences between MockLab online API mocking and Mockoon's desktop application and CLI mocking features
MockLab is an API mocking cloud services. It uses WireMock as its underlying engine and inherits most of its capabilities, while adding more possibilities like support for the OpenAPI specification. It enables developers to create mock REST APIs endpoints, intercept and proxy requests. The fake REST endpoints can adopt realistic behavior thanks to a request matching system and a templating language similar to Mockoon's one.
While Mockoon provides a similar mocking experience, it has a different approach as it offers an offline, privacy-friendly desktop application. Coupled with the CLI that allows you to deploy your REST mocks anywhere, it gives the power needed to automate your 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.
