Supabase: Open-Source Firebase Alternative for Backend and Database

What is Supabase?

Supabase is an open-source Firebase alternative that provides a complete backend-as-a-service platform with PostgreSQL database, real-time API, authentication, and storage capabilities. Built with focus on providing developers with powerful backend infrastructure without vendor lock-in, Supabase enables rapid application development with production-ready infrastructure. Over 500,000 developers use Supabase to build applications faster without managing complex backend systems.

Unlike Firebase ($0-45+/month) where application data is locked into Firebase’s proprietary system with limited control, Supabase uses standard PostgreSQL with open standards enabling complete data portability. Organizations deploy Supabase on-premises or use managed cloud hosting, maintaining complete autonomy over their application architecture.

Supabase serves as the complete backend platform. Mobile developers build iOS and Android apps with backend. Web developers build full-stack applications. Startups launch MVPs quickly without building backend infrastructure. Enterprises build scalable applications with PostgreSQL reliability.
