It's all open source: Supabase is built on top of other popular open-source packages, such as PostgREST for accessing your database directly from the client, and GoTrue for user authentication. All that, along with a nice admin interface so you can manage everything. If you wanted, you could host and manage these services on your own. If PostgREST does not fit your use case, you could host a server that will communicate with your Postgres database directly. And if you ever decide that Supabase is not for you, you could always migrate all your data somewhere else. At the end of the day, it's all in a Postgres database.
There is currently an open issue for Apple support as well, which is a requirement if you're building iOS apps and want to support third party logins.
That's all for the first part of this tutorial series on Supabase with Flutter, focusing on Authentication. You can find the full code on GitHub. I hope you found it helpful, and would love it if you could share some feedback in the comments! In the next part, we will take a look at Supabase's Database offering.
Relational database: Supabase is built on top of PostgreSQL, a powerful relational database that has been around for over 30 years. Firebase's Firestore and Realtime Database offerings are non-relational, so the choice between Supabase and Firebase might be as easy as relational vs non-relational, though there's more to it than that. Firebase is not open source, and has not been around as long as Postgres.
Getting started with Supabase is simple, so we won't go into much detail about its setup. Just head to the Supabase website and create a project.

GoTrue uses JSON Web Tokens (JWT) for authentication. On a successful sign in/sign up, the response contains an access token, and a refresh token. The access token is included in every request to Supabase. When decoded, this token contains the user's unique ID, and this is how Supabase knows which user is performing the request. Access tokens are short-lived, and expire by default every one hour (you can configure this through the admin interface, but only do this if you have a good reason). You can read more about JWT here.
