Storage

Upload and serve files from Cloud storage. Files are organized into buckets with configurable access control.

Adding uploads to your app

Tell the agent what you need:

Add a profile picture upload to the settings page with
drag-and-drop, preview, and a 5MB size limit.

It creates the upload component, configures the bucket, and handles access control.

Public vs. private buckets

Public buckets serve files directly via URL — good for product images, avatars, and anything meant to be shared.

Private buckets require authentication to access. Use signed URLs to grant temporary access to specific files:

const { data } = await supabase.storage
  .from('documents')
  .createSignedUrl('report.pdf', 3600); // expires in 1 hour
