Comparison between Mockoon and Stoplight's API mocking services

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

 What is Stoplight?

Stoplight is a cloud-based platform that provides tools for designing, documenting, and testing APIs. It offers hosted API mocks to simulate and validate API behavior in a collaborative environment. Stoplight also features a CLI tool called Prism, which allows developers to create and run mock servers locally based on OpenAPI specifications. Prism can validate requests and responses, enabling efficient prototyping and testing without the need for a fully implemented backend. Together, these tools ensure that API contracts are met and facilitate a streamlined API development workflow.

 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.
