Supabase

The open source Firebase alternative

Overview

What Supabase does

Supabase is an open source Firebase alternative providing all the backend services you need to build a product. It uses PostgreSQL as the database, provides instant APIs, authentication, real-time subscriptions, and storage.

What people use it for

  • Web application backends using Postgres plus auto-generated REST/GraphQL APIs
  • Mobile app backends via Flutter/Swift/Kotlin client libraries
  • AI applications using vector/embeddings storage
  • Authentication with 20+ social providers plus email/password
  • File and media storage (S3-compatible with CDN) and realtime sync over WebSockets

The honest half

Where it falls short

Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about Supabase.

  • Free tier projects auto-pause after 1 week of inactivity
  • Free tier hard caps: 500 MB database, 1 GB file storage, 5 GB egress/month, 50,000 monthly active users, max 2 active free projects per organization
  • Pro plan charges usage overages beyond included quotas, e.g. $0.00325 per MAU above 100,000 and $0.125/GB disk above 8 GB
  • SOC2/ISO 27001 certification and HIPAA (add-on) compliance require the $599/month Team plan; not available on the $25/month Pro plan

Cross-shopped

What people choose instead of Supabase

Each pairing was judged by two reviewers asking whether a buyer would genuinely weigh the two against each other. The ones that failed were deleted rather than published.
