FAQ

Firebase or Supabase?
Firebase = speed + mobile ecosystem, Supabase = SQL control + predictable costs.
Can we change backend later?
Yes, but it's never trivial. That's why the initial choice matters.
How to manage Security Rules?
It's critical. Bad rules = data leak. I make sure it's done correctly and audited.
