Comparison between Mockoon and Stoplight's API mocking services
Discover the differences between Stoplight and Mockoon API mocking services: deployment options, 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 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.
