1. Depends on whether you need RLS or not. We're working on improving the Better Auth + Supabase RLS story by collaborating with them, but if you're not relying on RLS for authorization, I’d go with Better Auth. You’ll get more features, and it’ll feel more integrated with your backend rather than your database. Plus, if you ever want to switch database providers you can.

2. Yeah, you’d need to migrate to Better Auth and move your user table to your main schema. We have a migration guide for Supabase.

3. It’s just additional features built on top of the framework, not a 3rd party auth service. You’ll still use the framework, and when you need those features, you can connect it to the infra to enable them.
