Databases and backend: questions people ask

What is the best database for a vibe-coded app?

Supabase. It gives you Postgres, login and file storage in one place, and tools like Lovable and Bolt.new connect to it out of the box.

Supabase or Firebase: which should I use?

Pick Supabase if you want SQL and the widest support from AI app builders. Pick Firebase if your team is already on Google Cloud.

Do I need row-level security?

Yes, if your app has user accounts. Without it, one user can often read another user's data. Our standard test checks that each backend makes this easy to set up.
