Supabase is an open-source backend-as-a-service built on PostgreSQL. It provides auth, database, real-time subscriptions, storage, and edge functions — positioning as a Firebase alternative with SQL instead of NoSQL.
Full BaaS stack on Postgres — auth, database, storage, real-time, and edge functions in one platform.
Outstanding developer experience. Postgres familiarity means most developers are productive immediately.
Deep Vercel, Next.js, and Prisma integration. REST and GraphQL APIs auto-generated from schema.
Free tier is genuinely useful. Pro at $25/mo. Dramatically cheaper than Firebase at most usage levels.
pgvector support for AI embeddings. Actively adding AI features for vector search and RAG applications.
Excellent documentation, active Discord, and very responsive to community feedback.
Enterprise tier handles production workloads. Scales with Postgres — battle-tested at large scale.
