An excellent open-source backend-as-a-service built on PostgreSQL, rightly appealing to developers wanting to avoid proprietary lock-in.

Supabase is an open-source backend-as-a-service (BaaS) platform, often presented as the Firebase alternative. Built on PostgreSQL, it provides a database, authentication, file storage, real-time APIs and serverless functions in a few clicks, with the option to self-host everything.

What is Supabase used for?

Supabase is used to quickly stand up the back-end of a web or mobile app without coding everything: a relational Postgres database with an auto-generated API, user management, storage and real-time subscriptions. Its grounding in PostgreSQL and open source appeals to developers who want to avoid lock-in and keep standard SQL, unlike Firebase.

Supabase or Firebase?

Against Firebase, Supabase bets on PostgreSQL (standard relational SQL), open source and self-hosting, where Firebase is more integrated with the Google ecosystem but proprietary and NoSQL. The choice depends on the data model and attachment to SQL and open source.

How much does Supabase cost?

The Free plan covers projects in development (500 MB database, 50,000 active users). The Pro plan is $25 per month with higher quotas, Team $599 for compliance and support, and Enterprise on quote. Beyond quotas, usage is billed.
