If you are creating an application and you need to simulate an API, with Mockoon you can create API simulation services. It's easy to use and it's free
One of the rare tools I use almost daily. We are behind a company firewall with no access to clients' APIs, mocking them really helps!
Mockoon is a fantastic time saver.
I've tried 2 other API mocking services before, Mockoon is by far the best.
Easy to use, fast, and free.
I gained so much time using this app both on personal projects and at work. You can create mock APIs in no time, either when you cannot access clients API or just want to quickly test an integration. Set up and forget it.
Mockoon being a desktop software, it also helps a lot when you don't have access to cloud solutions.
