The only truely freeing BaaS is Pocketbase. You can write your custom code in Go and deploy a single binary. Absolute control, simplest of the solutions. It is as close to pure magic and I have tried all the other bases like Supabase, Hasura, NHost etc.
Supabase developer here. We're big fans of Pocketbase here and love the stuff they're doing. I did some work with it early on and it's great, but since I'm not a Go developer, I found the customization options pretty lacking. I wish they'd develop a way to write custom code in Typescript or some other way to write custom database functions. I'm excited to see what's in store for the future of Pocketbase (as I've always been a fan of Sqlite and it's compactness and simplicity.)
