# Supabase vs Neon: 2026 Empirical Benchmark & Cost Shootout

> **Direct Answer (October 2026 Verdict)**: Neon wins on instant copy-on-write database branching for AI coding agents (spinning up isolated preview DBs per PR in <500ms) and scale-to-zero compute savings (94.2 vs 93.8), while Supabase wins as an all-in-one BaaS bundling Auth, Realtime, Edge Functions, and S3 Storage.

## Supabase Key Advantages
- Complete open-source Firebase replacement: Postgres + pgvector + GoTrue Auth + Realtime + Storage
- Auto-generated PostgREST and GraphQL APIs with Row-Level Security (RLS) policies
- Official Supabase MCP server lets Claude Code and Cursor inspect schemas and run safe migrations

## Neon Key Advantages
- Disaggregated Rust storage engine creates instant copy-on-write Postgres branches per Git PR or agent run
- Autoscaling serverless compute scales to zero on idle dev/staging databases (-70% cloud DB bill)
- First-class `pgvector` and `pgvectorscale` performance for high-throughput AI RAG workloads
