The funny thing is that it's been sort of a gateway drug into the Google Cloud Platform. After dipping your toe into the Firebase Realtime Database, you start using Firebase Cloud Functions and Firebase Storage, which steers you toward Google Cloud Functions and Google Cloud Storage.

AWS really needs to step up their game in this area to compete with GCP. Hopefully this project is a start.

It's an easy way to build out your own UX for authentication flows and customize the experience.
