Neon Has a Free Serverless PostgreSQL: Branching, Autoscaling, and Scale-to-Zero for Modern Apps

RDS charges $30/month for the smallest PostgreSQL instance — even when nobody's using it. Supabase is great but opinionated. PlanetScale was MySQL-only and shut down its free tier.

What if PostgreSQL scaled to zero when idle, branched like Git, and cost nothing for side projects?

That's Neon.

Free Tier

• 0.5 GB storage
• 1 project, 10 branches
• Autoscaling 0.25-2 compute units
• Scale to zero — $0 when not in use

Key Features

Database Branching

# Create a branch for testing — instant copy, no data duplication
neonctl branches create --name staging --parent main

# Each branch gets its own connection string
# Test migrations on staging without touching production

Serverless Driver (HTTP)

import { neon } from "@neondatabase/serverless";

const sql = neon(process.env.DATABASE_URL);

// Works in Edge Functions, Workers, Lambda — no persistent connection needed
const users = await sql`SELECT * FROM users WHERE active = true LIMIT 20`;
const user = await sql`INSERT INTO users (name, email) VALUES (${name}, ${email}) RETURNING *`;

Connection Pooling (Built-in)

# Standard connection (for long-running servers)
postgres://user:pass@host/db

# Pooled connection (for serverless — add -pooler to hostname)
postgres://user:pass@host-pooler/db
