Full-Stack React Native Expo + Supabase Template, Free

Looking for a full-stack React Native Expo + Supabase template (the zip you can start from)? The short answer: Expo plus Supabase is a full stack with almost no backend code, auth, a Postgres database, and storage, secured by Row Level Security so the app talks to the database directly and safely. Generate the UI free from a VP0 design, the free iOS design library for AI builders, wire Supabase, and follow the official quickstart. Build the screens, lean on RLS, and you have a real backend fast. about 76% of developers now use or plan to use AI tools in their workonsider the scale: C.

Who this is for

This is for builders who want a full-stack React Native app, front end plus backend, without writing a server, and want a free, ownable starting point rather than a paid template zip.

What the Expo + Supabase stack gives you

Supabase is the backend so you do not have to build one. Per the official Supabase Expo quickstart and the Expo using-Supabase guide, it provides authentication, a Postgres database with an auto-generated REST API, and storage, all secured by Row Level Security. The key point: because RLS policies control access per user, your app can query the database directly and the public anon key is safe to expose, so you skip a custom server for most features. Expo provides the front end and build pipeline, and React Native is the framework.

Layer	Supabase provides	Note
Auth	Email, OAuth, Apple sign-in	Add Sign in with Apple for 4.8
Database	Postgres + auto REST API	Query directly with RLS
Security	Row Level Security	Define policies first
Storage	File storage	Images, uploads
Front end	Expo + React Native	Generate UI from a VP0 design

Build it free with a VP0 design

Generate your own screens rather than buying a template zip. Pick a screen in VP0, copy its link, and prompt your AI builder:

Build this Expo React Native screen from the VP0 design at [paste VP0 link], wired to Supabase: auth where relevant, and RLS-protected Postgres queries for data, with storage for any uploads. Match the palette and spacing from the reference, and generate clean code I own.

Build the screens, lean on RLS

The reason this stack is fast is that the backend is mostly configuration. Generate the screens from VP0 references, wire Supabase auth, and define Row Level Security policies on your tables before the app queries them, since RLS is what makes direct database access safe. Use storage for uploads and add Sign in with Apple if you offer social login. Keep any service-role key strictly server-side; the app uses the anon key, which RLS governs. Following the official quickstart for setup and generating your own UI gives you a full-stack app you own, with no template license and a real, secure backend in place fast.

Common mistakes

The first mistake is querying tables before defining RLS policies, which is insecure. The second is putting a service-role key in the app instead of the anon key. The third is building a custom server for what Supabase already handles. The fourth is skipping Sign in with Apple when you offer social login. The fifth is buying a template zip when a free VP0 design plus Supabase does it.

Key takeaways

• Expo + Supabase is a full stack with almost no backend code.
• Supabase gives auth, a Postgres database with REST API, storage, and Row Level Security.
• RLS lets the app query the database directly and safely; define policies first.
• VP0 gives you the UI free; generate your own screens instead of buying a zip.
• Use the anon key in the app and keep service-role keys server-side.

Frequently asked questions

How do I build a full-stack React Native app with Expo and Supabase? Pair Expo with Supabase for auth, Postgres, and storage, generate the UI from a free VP0 design, and use RLS so the app queries the database directly without a server.

Is it safe to call Supabase directly from a React Native app? Yes with RLS on. Supabase secures data with RLS, so the anon key is safe to expose; define policies before relying on direct access.

What is the best free template for an Expo + Supabase app? Generate your own from VP0 (free UI) plus the official Supabase Expo starter for the backend, with no kit purchase.

What does Supabase give me out of the box? Auth, a Postgres database with an auto REST API, storage, and Row Level Security, covering most of a typical backend without a server.
