Now this is what the OP was looking for, and it so happens that I'm going to look into these too! Thanks!
Quick question because I have no idea what I'm doing: is there any integration in either of those that you know of for one or more 3rd party auth system(s)? I don't want to write my own auth!
I'm not sure about ToolJet, but I know it's possible to use external auth systems with AppSmith.
It supports at least Firebase and Supabase. I think self-hosting Supabase + AppSmith could be a good combo for quickly hashing out prototypes or internal company apps.
