Supabase

What is Supabase in Build

Supabase turns a front end you generate in Build into a fully working app. Without it, your project looks and behaves like the real thing, but nothing is actually saved. Connecting Supabase adds a real database, real logins, and real storage behind the scenes, called Cloud inside Build.

How to Connect Supabase

In the composer, click the plus icon, then Connectors, then Supabase, and click Connect. You can also find Cloud represented by the purple cloud icon in the preview toolbar once your project is open.

What It Unlocks

Once connected, your app can save real data, remember signed in users, and store files, rather than just simulating the experience. This is what turns something like a storefront or a signup form from a convincing demo into a real, working product.
