Supabase vs Firebase: Choosing the Right Backend for Your App

January 12, 2026 5 min read

The Backend Battle

When spinning up a new web app or React Native project, you need a Backend-as-a-Service (BaaS) to handle auth, database, and storage. The two heavyweights are Firebase (Google) and Supabase (Open Source).

Why Firebase is Losing Ground

Firebase uses a NoSQL database (Firestore). While great for simple chat apps, NoSQL becomes a nightmare when building complex B2B SaaS platforms that require relational data (e.g., Users belong to Organizations, Organizations have Invoices).

The Supabase Advantage

Supabase is built on top of standard PostgreSQL. You get all the relational power of SQL, combined with the real-time subscriptions and easy authentication of Firebase. Plus, there is no vendor lock-in; you can always export your Postgres database and host it yourself.

At Oktuv, Supabase is our default BaaS for rapid MVP development. It allows us to ship enterprise-grade data structures in a fraction of the time.
