Quick Verdict
Choose Supabase if you prioritize open-source flexibility, SQL, and a relational data model. Choose Firebase if you want a mature, fully-managed NoSQL platform with deep Google ecosystem integration and a generous free tier.
Supabase is an open-source backend-as-a-service built on PostgreSQL, offering a relational database with real-time capabilities and REST/GraphQL APIs. Firebase is Google's managed NoSQL platform, featuring a real-time document database, extensive built-in services, and a pay-as-you-go model. Their core architectural difference is relational SQL versus flexible NoSQL. Supabase targets developers wanting database control and open-source benefits, while Firebase appeals to those seeking rapid development with minimal backend management.

Choose Supabase if...
Supabase is superior when your application relies on complex queries, joins, and relational data integrity, or when you require the ability to self-host or deeply customize your backend. It's also a compelling choice for teams with strong SQL expertise or those specifically migrating from Firebase to a PostgreSQL-based system.
Choose Firebase if...
Firebase is the better choice for rapid prototyping and mobile-first applications, especially when leveraging other Google services like Analytics, Cloud Functions, or ML APIs. Its real-time NoSQL database excels at simplicity and speed for unstructured data, and its generous free tier and pay-as-you-go model are ideal for projects with unpredictable scaling needs.
