Is Firebase or Supabase better?

Supabase is better for SQL-based apps, open-source requirements, and PostgreSQL users. Firebase is better for real-time apps, mobile development, and teams already in the Google ecosystem. Supabase is the open-source Firebase alternative.

Is Supabase replacing Firebase?

Supabase has gained massive traction as a Firebase alternative, particularly among developers who prefer SQL over NoSQL, want self-hosting, or prefer open-source tools. It hasn't replaced Firebase but is a serious competitor, especially for web apps.

Who Should Choose What?

Choose Firebase if:

You're building mobile apps (iOS/Android), need Firebase Cloud Messaging for push notifications, or want deep Google Analytics integration. Firebase's SDK ecosystem for mobile is unmatched.

Choose Supabase if:

You prefer SQL, want open-source infrastructure, plan to self-host, or are building a web app that needs relational data. Supabase's PostgreSQL base makes it easier to query complex data and migrate later if needed.

FAQ

Can you migrate from Firebase to Supabase?

Migrating from Firebase's Firestore (NoSQL) to Supabase's PostgreSQL (SQL) requires data model redesign — not a simple export-import. Auth migration is easier as both support email/password and OAuth providers. Plan for significant refactoring if switching from a production Firebase app.

Is Supabase free forever?

Supabase's free tier includes 500MB database, 5GB bandwidth, and 50MB file storage per project, with no time limit. Projects are paused after 1 week of inactivity on free. The $25/month Pro plan removes inactivity pausing and increases all limits significantly.
