Supabase

Open-source Firebase alternative with PostgreSQL, auth, storage, and realtime APIs.

Overview

Supabase is an open-source backend platform built on PostgreSQL that provides a complete development environment for building production-grade applications. It combines a managed Postgres database with integrated authentication, instant REST/GraphQL APIs, edge functions, realtime data synchronization, file storage, and vector embeddings—all accessible through a unified dashboard.

The platform is designed for developers who want to build and scale applications without managing infrastructure. Every project includes a full Postgres database with Row Level Security, and the platform supports multiple frameworks including React, Next.js, Vue, Flutter, and Python. Supabase emphasizes developer experience with comprehensive documentation, local development tools via CLI, and production-ready templates.
