Supabase
An open-source backend platform giving you a Postgres database, auth, file storage, and auto-generated APIs in one dashboard.
Analogy
Like a giant labeled filing cabinet plus a security guard for your app's data.
Why it matters
It's a fast way to add a real database and logins to a Next.js app (this hub stores Updates and Resources in it).
In practice
You store users and saved resources in Supabase and read them from your app.
