a) Is this for rapid prototypes? (web? mobile?) b) Do you have a microservice architecture and you want to mock out one of the services? (dev? ci?) c) something else?
Lets say the generator looks at your schema and generates an api, how much would you want to tweak/customize that api?
Is the mock api returning data based on what's in the database? If so, can the mock api mutate data in the database?
