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

 What is Requestly?

Requestly is a tool designed for modifying and testing network requests directly within the browser, often used by developers to intercept, edit, and redirect HTTP requests and responses. With a browser extension and cloud capabilities, Requestly allows users to configure custom rules to modify headers, rewrite URLs, and redirect API requests, making it useful for debugging and testing purposes. It includes collaboration features and integrations that enable teams to share and synchronize rule settings. Requestly operates across platforms, with a focus on front-end testing and debugging in web applications.

 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.
