it just work, the ui is very intutitive as well if you're having problem, just reload the tab to make sure the mock applied
Only allows me to return json. i want to return html
This makes it super easy for the FE work to happen in parallel with BE. I just need to share the contract and done. The interface is super clean too! Thanks bud.
Too Easy to work with .
Great tool to work with. Thanks for rolling it out. Excited for new features. :)

Works great, helps a lot
Simple and great! I think the one basic thing that is missing I think is the ability to give a custom name to the mock data. The URL name works, but if you want different mocks for the same URL, it's hard to remember which mock data set I'm turning on.
