## Summary

Supabase is the open-source Firebase alternative built on PostgreSQL, providing developers with a full backend including database, authentication, storage, and real-time subscriptions.

## Company Overview

Supabase is an open-source backend-as-a-service platform that provides developers with a fully managed PostgreSQL database alongside a suite of backend services—authentication, file storage, edge functions, and real-time subscriptions—through a Firebase-compatible API. Founded in 2020 by Paul Copplestone and Ant Wilson, Supabase chose PostgreSQL as its foundation, betting that developers would prefer a fully relational, SQL-native database over the document-oriented approach of Firebase.

The platform has become one of the fastest-growing developer tools in history, reaching 1 million databases and millions of users within its first few years. Supabase's open-source model allows developers to self-host or use the managed cloud service, and the company's transparent product development—building in public with community involvement—has cultivated an exceptionally engaged developer community. The platform's row-level security, foreign keys, and SQL support address capabilities that Firebase's NoSQL model cannot provide, making it particularly popular for applications with complex data relationships.

Supabase has raised over $200M from investors including Coatue, a16z, and YC. The company operates in the rapidly expanding backend-as-a-service market where developer experience and flexibility are the primary purchase criteria. Supabase's combination of open-source flexibility, PostgreSQL reliability, and Firebase-level ease of use has made it the default backend choice for a generation of startups and full-stack developers.
