You ever heard about Apiary.io? It’s a really awesome tool that I’m using right now. It’s a bit like mockable.io, but when working in apiary, at the same time you are making a document. A document that can also work like a contract for your Frontend and Backend team.
Sometimes the backend is not ready yet, so we as Frontenders need some tools to mock these endpoints. Apiary is kinda the same as all the other mocking tools I guess, but the way how it documents your API is just something that I have not seen yet.
Maybe there are others like Apiary? Oh well, for now, Go Apiary!
