What Firebase is
Firebase is Google's comprehensive platform for solving all mobile and web backend needs via a single SDK. It lets developers build 'real-time' apps without server management. Its Firestore DB scales infinitely on Google Cloud. It's a massive ecosystem that also manages analytics, crash reports, A/B tests, and push notifications from a single panel.
What Supabase is
Supabase is the open-source and PostgreSQL-based alternative to Firebase. It offers everything a developer needs (Database, Auth, Storage, Edge Functions) in one package. Its primary advantage is leveraging the power of Postgres, allowing you to use all the capabilities of SQL. The 'Realtime' feature reflects database changes in the UI instantly, speeding up backend tasks that would normally take weeks into just hours.

Firebase: pros & cons
- Speed: Set up a functioning backend and auth system in as little as one day.
- Google Synergy: Works perfectly with Google Analytics and Google Cloud Platform.
- Cömert Free Plan: Costs are zero for many small to medium-sized projects.
- Real-Time Sync: The leader for apps needing instant data updates like chat apps.
- Lock-In: Moving away from Firebase is very difficult due to its unique NoSQL structure.
- Query Limits: Not as flexible as SQL for very complex relational data queries.
- Cost Prediction: 'Pay-as-you-go' can strain budgets if traffic spikes unexpectedly.
Supabase: pros & cons
