Mockoon is the easiest and quickest way to design and run mock APIs. No remote deployment, no account required, free and open-source.
It combines a desktop application to design and run mock servers locally, and a CLI to self-host your fake APIs. A cloud is also available to collaborate with your team, keep your data in sync, and deploy your mock APIs.
API mocking helps you speed up development and third-party API integration by reducing dependency on external services and their limitations: rate limits, costs, availability, etc. It also allows you to test your applications in a controlled environment with predictable responses, status codes, and latencies, and easily simulate edge cases and error scenarios. Finally, you can onboard new team members faster by providing them with a consistent and reliable environment to test and develop their applications.
