Best for: developers who want a Postgres-based backend they can self-host later, rather than a proprietary NoSQL platform like Firebase
Pricing: Free at $0/month (2 projects, 500MB database); Pro from $25/month with usage-based overages; Team at $599/month; Enterprise custom.
- Supabase's Pro plan starts at $25/month with a $10/month compute credit included; the Free plan is $0/month with up to 2 projects.
- Supabase's core stack (Postgres, PostgREST, GoTrue, Realtime, Storage) is Apache-2.0 licensed and self-hostable via the supabase/supabase GitHub repo, which has more than 108,000 stars.
- Supabase auto-generates REST, GraphQL, and Realtime APIs directly from a project's Postgres schema.
- Supabase holds a 5.0/5 rating from 861 reviews on Product Hunt.
- The Team plan costs $599/month and adds SOC2/ISO 27001 compliance and 14-day backup retention.
Limitations: Usage-based overages (per-project compute, MAU, egress) can push real bills well past the $25/month Pro sticker price.; Free-tier projects pause after 7 days of inactivity.; Row Level Security has a steeper learning curve than Firebase's simpler client-side rules for teams new to SQL.

What is Supabase?
Supabase is an open-source backend platform built on Postgres, marketed as "the open source Firebase alternative." Each project gets a dedicated Postgres database plus auto-generated REST, GraphQL, and Realtime APIs derived from that database's schema. Beyond the database, Supabase bundles authentication (email, 20+ OAuth providers, Row Level Security for per-row authorization), S3-compatible object storage served through a global CDN, WebSocket-based realtime sync for database changes and presence, Deno-based edge functions, and a pgvector-powered vector store for AI embeddings. The core components are Apache-2.0 licensed and self-hostable; the hosted dashboard at supabase.com is Supabase's managed commercial product built on that open-source stack.
Supabase is an open-source backend platform built directly on Postgres, positioned explicitly as an alternative to Firebase. It bundles a dedicated Postgres database, authentication with 20+ social providers and Row Level Security, S3-compatible file storage, realtime websocket sync, and Deno-based edge functions, auto-generating REST, GraphQL, and Realtime APIs from the database schema. Pricing starts free (2 projects, 500MB database, 50,000 monthly active users) and Pro is $25/month with a $10/month compute credit included; Team is $599/month with SOC2/ISO 27001 compliance. Supabase's core stack — Postgres, PostgREST, GoTrue auth, Realtime, and Storage — is Apache-2.0 licensed and self-hostable from the supabase/supabase GitHub repository, which has more than 108,000 stars; the hosted dashboard and managed infrastructure at supabase.com are Supabase's own commercial offering built on that open-source base. Supabase holds a 5.0/5 rating from 861 reviews on Product Hunt, where reviewers praise the developer experience and generous free tier while noting that usage-based overages (per-project compute, MAU, egress) can push bills well past the advertised $25/month Pro price.
Standout feature: Auto-generated REST, GraphQL, and Realtime APIs derived straight from a project's Postgres schema, with Row Level Security enforcing per-row authorization at the database layer instead of in application code.
Biggest weakness: Pricing beyond the $25/month Pro base is usage-based and billed per project rather than per account, so teams running multiple projects or exceeding the 100,000 MAU / 250GB egress limits can see invoices climb well past the advertised starting price.
Pros
- Full Postgres database rather than a proprietary NoSQL store, so existing SQL skills and extensions like pgvector and PostGIS carry over directly.
- Auto-generates REST, GraphQL, and Realtime APIs from the schema, with Row Level Security for per-row authorization.
- Apache-2.0-licensed core stack is self-hostable, avoiding hard vendor lock-in.
- Free tier includes unlimited API requests, 50,000 monthly active users, and a 500MB database with no time limit on the account.
Cons
- Compute is billed per project, so accounts running several projects stack recurring charges beyond the flat $25/month Pro fee.
- MAU overage ($0.00325/user past 100,000) and egress overage ($0.09/GB past 250GB) can produce unpredictable invoices at scale.
- Free-tier projects pause automatically after 1 week of inactivity.
- Row Level Security has a steeper learning curve than Firebase's simpler client-side security rules for teams new to SQL.
