I'm using Postgraphile in production on 2 real-world projects and it saves me an incredible amount of time. I spend 90%+ of my time on the front-end because the api is all automated.
Postgrahile allows you to rename/disable api endpoints if needed.
Postgraphile rocks. And it's written in modualar Javascript, so I can hack it if I need to. Unlike Hasura.
I tell friends and family about it all the time, but I can't seem to convince anyone to use for it every subscription like I do.
