Migrating from Firebase to Superbase?

Hi all

I'm looking to open source my project and while I used Firebase to get started, I don't feel right about using a closed source platform for an open source project.

Should it be a drop in job ?

It's a flutter web basic crud app that uses anonymous auth.

Firebase is like an old friend, but I don't like relying on closed source tech.

I'm also thinking of migrating the flutter web project to React. How's Superbase's support there ?
