I've started working on a similar platform where the goal is to make building CRUD apps wildly simple. The plan going forward will be to layer on more sophistication after the core foundation is extremely solid.
The platform uses Mongo for the dynamic data tables which is a game changer for tools like this. Postgres jsonb data would also work, but Mongo just feels more natural to me.
I've named the platform Webase. Check it out here: https://www.webase.com
Note: this is very basic currently but consistently getting better!
