Student Small-Business (50 or fewer emp.) 10/1/2021 "Solid tool for Abstract Programming Interface (API) design" 4.5/5 What do you like best about Mockoon? I like the ability to set constraints on what each API can accept and customize GET, POST, DEL, and FETCH endpoint type requests. It visualizes what you input very nicely and makes it aesthetically pleasing to use for API design development. Review collected by and hosted on G2.com. What do you dislike about Mockoon? It does not support features to visualize the input and output data of each API endpoint you make. This is a pretty essential feature in the API software engineering process, so it is missing key feature. Review collected by and hosted on G2.com. What problems is Mockoon solving and how is that benefiting you? I am solving the problem of needing to design API for software engineering practices. I have realized the benefits of having a desktop app to create design and mock ups for the backend of my web applications. This includes API endpoints (.../'endpointurl'), and lets you visualize how they can be interacted with (GET, POST most commonly). Review collected by and hosted on G2.com.
