What Supabase provides

Supabase is an open-source backend platform. When connected to Fastshot, your app can use:
  • Authentication — email/password, Google, and Apple sign-in
  • Database — PostgreSQL with real-time subscriptions
  • Storage — file and image uploads with public URLs

​
Connecting Supabase

When your app needs backend features (user accounts, saving data, file uploads), the AI will prompt you to connect Supabase. An inline connect widget appears in the chat.
  1. Click the connect button when prompted
  2. Authorize Fastshot to access your Supabase project
  3. The connection is established automatically
If you don’t need a backend yet, you can skip the Supabase prompt. The AI will use local storage as a fallback. You can always connect later.

​
Authentication

Once connected, you can add auth to your app:
  • “Add a login screen with email and password”
  • “Add Google sign-in”
  • “Add Apple sign-in”
  • “Add a password reset flow”
The AI generates the authentication UI and connects it to Supabase Auth. Session management is handled automatically.

​
Database

Store and retrieve data with Supabase’s PostgreSQL database:
  • “Save user profiles to the database”
  • “Add a favorites list that persists across sessions”
  • “Show real-time updates when new items are added”
The AI generates the database queries, table structures, and real-time subscription code.

​
Storage

Upload and manage files:
  • “Let users upload profile photos”
  • “Add image attachments to posts”
  • “Store receipt photos with expenses”
Files are uploaded to Supabase Storage buckets with proper access control policies. Storage limits:
  • 10 MB per file
  • Image files only (image/* MIME types) by default

​
Without Supabase

If you choose not to connect Supabase, your app uses:
  • AsyncStorage for local data persistence
  • Zustand for in-memory state management
  • No authentication or cloud storage
You can connect Supabase at any time to upgrade to cloud-based features.
