Firebase Hosting is great out of the box — but by default you only get a web.app or firebaseapp.com domain. That’s a missed opportunity for branding and SEO. I’ll show you how to connect a custom domain in this article.

How it works

Once your app is deployed (firebase deploy), go to the Firebase Console → Hosting section and look for domains.
