01. Overview & Pitch Details
SECTION 01 / 05Executive Pitch Summary
Building a scalable backend requires stitching together separate database servers, authentication providers, storage buckets, and real-time WebSocket infrastructure. Proprietary NoSQL platforms like Firebase create vendor lock-in and complex query limitations.
Supabase provides a complete open-source backend built on enterprise-grade PostgreSQL. Every project gets a full Postgres database with Row Level Security, instant auto-generated REST and GraphQL APIs, real-time subscriptions, file storage, and serverless Deno Edge Functions.
Core Value Propositions
- Β· Full Dedicated PostgreSQL: Full SQL power, pgvector AI embeddings, PostGIS extensions, and custom triggers
- Β· Row Level Security (RLS): Fine-grained database access rules executed directly at the Postgres engine level
- Β· Instant Auto-Generated APIs: Fast RESTful endpoints generated automatically from your table schema
- Β· Real-Time Database Listeners: Subscribe to database INSERT, UPDATE, and DELETE events via WebSockets
- Β· Vector Embeddings with pgvector: Store, index, and query high-dimensional AI vector embeddings natively
