I don't see how the target can be entirely non-technical people, since this still assumes some knowledge around databases/functions/REST/HTTP/Schemas/etc.
Technical people have very little reason to use this, since this platform is a walled garden of proprietary tooling, and there's only so much you can achieve with abstractions and fancy ORM. You won't be able to break out of the mould when the time comes, so why waste your time in the first place? Do it right the first time and maintain your flexibility and freedom later on.
I believe the only remaining target audience here is technically-inclined people that want to build a cheap prototype quickly, just to test ideas. This is a playground basically.
