Quick Comparison

Side-by-side comparison to help you decide.

Criterion	Supabase	Firebase
Underlying database	PostgreSQL - full SQL, JSONB, RLS, pgvector, PostGIS	Firestore - document store; proprietary NoSQL with eventual consistency
Query language	SQL via PostgREST auto-generated REST API, or direct connection	Firestore query API - no JOINs; denormalisation required for complex reads
Vendor lock-in	Low - PostgreSQL is open source; self-host with any managed Postgres	High - Google Cloud Firebase; Firestore data is hard to migrate off
Auth	Supabase Auth - JWTs, social providers, Row Level Security integration	Firebase Auth - excellent, battle-tested, broad provider support
Real-time	Postgres logical replication via Realtime channels	Firestore real-time listeners - very mature; first-class real-time experience
Storage	Supabase Storage - S3-compatible; RLS policies on buckets	Firebase Storage - Cloud Storage for Firebase; GCP-backed

Our Verdict

Choose Supabase for any new project where long-term data ownership matters or where PostgreSQL's query expressiveness and JSONB support are needed. The SQL foundation means you can write complex queries today, add pgvector for AI features tomorrow, and migrate to a self-hosted PostgreSQL instance if you outgrow Supabase's pricing. Choose Firebase if you need the most battle-tested real-time listener experience, are already deep in the Google Cloud ecosystem, or your data model maps naturally to Firestore's document structure. For Australian businesses concerned about data sovereignty, Supabase's PostgreSQL base and self-hosting option is a meaningful advantage.

Choose Supabase when:

✓ You want PostgreSQL's SQL expressiveness alongside real-time and auth
✓ Data sovereignty - the ability to self-host or migrate off is important
✓ Adding pgvector for semantic search or AI embedding storage
✓ Row Level Security (RLS) is the preferred authorisation model

Choose Firebase when:

✓ Your data model is document-oriented and denormalisation is acceptable
✓ You are already in the Google Cloud / Firebase ecosystem
✓ Firebase's real-time listeners are a core product requirement and maturity matters
✓ You need Firebase's offline persistence for mobile apps

Frequently Asked Questions

Pricing depends on what you need - a simple web app costs less than a complex system with multiple integrations. We provide fixed-price proposals after a free discovery session.

Our core stack is Next.js, React, and TypeScript, but we select technology based on your project needs. We have experience with Python, Node.js, PostgreSQL, and all major cloud platforms.

Yes, our team has experience with both Supabase and Firebase. We choose the right tool based on your project needs and recommend accordingly during our free assessment.

Yes. Every project includes 3 months of post-launch support covering bug fixes, performance tuning, and minor feature additions. We also offer ongoing retainer plans.

Timelines depend on scope, but most projects go from kickoff to launch in 4-8 weeks. A working prototype is ready within the first 2 weeks for early feedback.
