Discover the differences between ReadyAPI and Mockoon API mocking services: deployment options, features, and more

 What is ReadyAPI?

ReadyAPI (formerly SoapUI) is a comprehensive API testing tool that facilitates the creation, testing, and monitoring of APIs. While secondary, it offers API mocking capabilities, allowing developers to simulate REST, SOAP, and other web services. Its feature set includes request and response validation, scripting, and automated test generation.

 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 Pro is also available for teams and organizations looking for a complete collaboration platform. It can be deployed on your own private infrastructure or used as a managed cloud service, enabling teams to collaborate in real time and deploy mock APIs while choosing where their data and services run.
