Supabase

HybridOpen sourceReviewed 2026-07-12

A full backend that is still just Postgres underneath.

What it does

Postgres-based backend platform with auth, storage, realtime, and vector search for application data.

Durable strength

Standard Postgres under the hood — your data stays in a portable, open format you can export or self-host.

Verify before adoption

⚠️ Row Level Security defaults on your tables, current free-tier pause policy, and pgvector limits for embedding workloads.

In the Human × AI workflow

Prototype

Builders pair AI code generation with Supabase's auto-generated APIs — describe a table, get REST and realtime endpoints without writing a backend.

Build

Common pattern: Row Level Security policies written and reviewed with an AI assistant, then tested with the SQL editor before an app ever touches the data.

Operate

pgvector inside the same database powers retrieval for AI features — one connection string for app data and embeddings, no second vector store to babysit.
