Supabase vs Firebase

Supabase is the open-source Firebase alternative built on PostgreSQL with native vector search via pgvector. Firebase offers a mature, fully managed NoSQL ecosystem with Firestore, Auth, and Cloud Functions. Supabase wins on SQL power, open-source flexibility, and AI/vector capabilities; Firebase excels in real-time sync, mobile SDKs, and Google Cloud integration.
