Supabase

Overview

Supabase is an open-source Firebase alternative headquartered in San Francisco, United States, founded in 2020 by Paul Copplestone and Ant Wilson. Supabase provides PostgreSQL database, authentication, realtime subscriptions, storage, and edge functions as backend services, auto-generating RESTful APIs to help developers build app backends fast.

Built on open source, Supabase can be self-hosted or cloud-managed, with a free tier supporting 2 projects and basic resources. Compared with Firebase, Supabase uses standard SQL and PostgreSQL, making it popular among developers. For database selection, see the website database selection guide; this page belongs to the automation tool providers category.
