If you've been building with Supabase, you know their Storage API is fantastic for web apps. But sometimes, you just need your files on your local machine—whether for a manual backup, bulk editing, or migrating data.

While you could write a script using the Supabase SDK, there is a much faster, "no-code" way to manage your files like a Pro: Cyberduck .

Note: Cyberduck is an official Supabase partner integration . It is a secure, open-source tool that Supabase explicitly recommends for managing storage via the S3 protocol. You can find the official integration page here .

Phase 1: Generate Your S3 Credentials

Before opening Cyberduck, you need to give it permission to talk to your Supabase project via the S3 protocol.

Log in to your Supabase Dashboard .

Under Access Keys , click Create Access Key .

Give it a description (e.g., "Local Backup") and click Create .

Important: Copy your Access Key ID and Secret Access Key immediately.…
