Stay free if you only need basic features. Upgrade if you need advanced features. Most solo builders can start free.
Supabase offers full SQL support with PostgreSQL (joins, transactions, complex queries) while Firebase uses a NoSQL document model. Supabase real-time works through database change detection with row-level security filtering. Firebase has broader global infrastructure and stronger offline sync. Choose Supabase for relational data and SQL power; Firebase for simpler data models needing Google ecosystem integration and offline-first mobile apps.
Yes, migration is straightforward since Supabase is managed PostgreSQL. Import schema and data using standard PostgreSQL tools like pg_dump/pg_restore. Supabase provides migration guides and the CLI includes migration management. You can enable real-time features on existing tables with simple SQL commands after migration.
Yes. The pgvector extension enables vector similarity search directly in PostgreSQL, so you can store embeddings alongside relational data and run hybrid queries (vector search + SQL filters) in a single database. This makes Supabase practical for RAG pipelines, semantic search, and recommendation engines without needing a separate vector database.
On the Pro plan ($25/month), resources beyond included limits are billed at pay-as-you-go rates. Database storage beyond 8GB costs $0.125/GB. Bandwidth beyond 250GB costs $0.09/GB. Additional Edge Function invocations are $2 per million. The free tier has hard limits — your project pauses if you exceed them rather than incurring charges.
Yes. The Team plan ($599/month) includes SOC2 compliance, priority support, and organization-level management. Enterprise plans add HIPAA compliance, dedicated infrastructure, custom SLAs, and point-in-time recovery. Thousands of production applications run on Supabase including companies like Mozilla, PwC, and Humata.
