Backend and user accounts

Most real apps need to remember things: users, their data, their files. In Zzz, all of that runs on Supabase, connected in one click. You never write backend code: you ask for features and Zzz wires them.

What you can ask for

• User accounts: "add sign up and login" gives your app complete, secure authentication screens.
• Saved data: "let users save their workouts" creates the right tables and hooks them to your screens.
• File uploads: "let users add a profile photo" handles upload, storage and display.
• Live features: chats, feeds and leaderboards that update instantly for everyone.

See your app’s data

The builder has a Backend panel where you watch your app live: the users who signed up, the data they created, the emails your app sends. No dashboard to configure, it’s just there.

A real backend, not a toy

Behind the scenes it’s a production-grade Postgres database with proper security rules. Your users' data is isolated and protected by default, and it belongs to you: you can open your Supabase dashboard anytime.

Good to know

• Connect Supabase early if your idea involves accounts: flows like "save my progress" feel natural from day one.
• Start on the free Supabase plan: it comfortably covers building and your first users.
