Mockoon

Write an API in 30 minutes. Share it with your teammates or customers. Let them use the API mock to take your API for a spin--without writing any code. Iterate, rinse & repeat. Coding can wait until you know what your developers really need. DNA for your API, powerful, open sourced and developer-friendly. The ease of Markdown combined with the power of automated mock servers, tests, validations, proxies, and code samples in your language bindings. It's often hard to see how an API will be used until you have the chance to code against it. What wireframes are for UI design, a server mock is for API design. A quick way to prototype an API - even before you start writing code. Two clicks will link Apiary to a repository of your choice. It’s up to you whether you make the API Blueprint private or public and let the community contribute. We update API docs every time you commit, and we push commits to the repo whenever you update your documentation at Apiary. It's a virtuous cycle.

If you want to create a simple API for testing purposes, simply enter a response body and get your custom API URL. Use Mocki to create a fully-fledged mock API. Using Mocki you can create, run, and deploy mock APIs. Use your mocks to design your API, serve static responses, simulate error scenarios, and remove dependencies to external services.

Using our managed hosting solution your mock service is always available for any consumer. Access a dashboard to gather insights on how your mock service is used. Using our open source CLI you can run your services locally. This enables you to run your service without requiring an internet connection to reach external services. A mock API can also be useful when testing backend apps. A common case is that your API or service needs to call external services over HTTP.
