Comparison between Mockoon and MockServer's API mocking services

Discover the differences between MockServer and Mockoon API mocking services: cloud offer, features, and more

 What is MockServer?

MockServer is a flexible tool used for mocking and proxying HTTP and HTTPS requests. It allows developers to create and simulate complex request-response behaviors for testing and development purposes. With MockServer, users can mock various scenarios by defining expected requests and corresponding responses, enabling the testing of edge cases and failure scenarios. It supports both REST and SOAP APIs and can be used for load testing and functional testing. Additionally, MockServer can be integrated into CI/CD pipelines to automate testing processes and ensure consistent API behavior throughout development cycles. Users can configure MockServer through a simple JSON configuration or programmatically via its Java and JavaScript clients.

 What is Mockoon?

Mockoon is a set of open-source tools that allow developers to mock APIs quickly and easily. It offers an offline-first and privacy friendly desktop application to design and run mock APIs locally. A CLI and various libraries are also available to deploy your mock APIs anywhere: CI/CD pipelines, servers, etc.

Mockoon features include a powerful templating system to generate dynamic and realistic mock data, a rules system, a proxy mode to partially mock API endpoints, and many customization options: status codes, dynamic headers, TLS, file serving, etc.

Mockoon Cloud is also available for teams and organizations looking for a cloud-based solution. It enables teams to collaborate on API mocking projects and share mock APIs with others by deploying them to the cloud.
