Neon vs Supabase vs PlanetScale (2026 Comparison)

Three managed databases dominate the developer ecosystem in 2026. Neon is serverless Postgres. Supabase is Postgres + everything. PlanetScale is serverless MySQL. Here's which one to pick.

Quick Verdict

• Neon — Best serverless Postgres. Scale to zero, branching, cheapest for dev.
• Supabase — Best all-in-one (database + auth + storage + real-time). Most features.
• PlanetScale — Best for MySQL shops. Schema branching, no downtime migrations.

The Key Difference

	Neon	Supabase	PlanetScale
Database	PostgreSQL	PostgreSQL	MySQL (Vitess)
Focus	Serverless Postgres	Backend-as-a-Service	Serverless MySQL
Scale to zero	✅	❌ (always running)	✅
Extras	Branching, autoscaling	Auth, storage, real-time, edge functions	Branching, insights

Pricing

	Neon	Supabase	PlanetScale
Free tier	512MB, scale-to-zero	500MB, 50K MAU auth	5GB, 1B row reads/mo
Pro	$19/mo	$25/mo	$29/mo
Pricing model	Compute hours + storage	Fixed tiers	Row reads/writes + storage
Scale to zero	✅ (free tier stays free)	❌	✅

Real cost at startup scale (1GB data, moderate traffic):

• Neon: $19/mo
• Supabase: $25/mo
• PlanetScale: $29/mo

But Supabase includes auth, storage, and real-time — those would cost extra with Neon or PlanetScale.

Database Branching

Both Neon and PlanetScale offer database branching — like git branches for your database:

Neon

# Create a branch (instant, copy-on-write)
neonctl branches create --name feature-xyz

# Each branch gets its own connection string
# Use in preview deployments (Vercel integration)

Neon branches are instant (copy-on-write, not a full copy). Perfect for preview deployments — each Vercel preview gets its own database.

PlanetScale

# Create a branch
pscale branch create my-db feature-xyz

# Make schema changes on the branch
pscale shell my-db feature-xyz
ALTER TABLE users ADD COLUMN avatar_url TEXT;

# Create a deploy request (like a PR)
pscale deploy-request create my-db feature-xyz

PlanetScale treats schema changes like PRs. Review schema diffs before deploying to production. Zero-downtime migrations.

Serverless Compatibility

	Neon	Supabase	PlanetScale
HTTP driver	✅ (@neondatabase/serverless)	✅ (supabase-js)	✅ (@planetscale/database)
Edge runtime	✅	✅	✅
Vercel integration	✅ Native	✅	✅
Cold start	~100ms	N/A (always running)	~100ms

All three work with serverless. Neon and PlanetScale scale to zero (cheaper for dev/staging). Supabase always runs.

Developer Experience

Neon

Pure database. Connect with any Postgres client or ORM (Drizzle, Prisma). Dashboard for SQL queries and branch management.

import { neon } from '@neondatabase/serverless'
const sql = neon(process.env.DATABASE_URL)
const users = await sql`SELECT * FROM users WHERE id = ${id}`

Supabase

Full platform with client SDK:

import { createClient } from '@supabase/supabase-js'
const supabase = createClient(url, key)

// Database
const { data } = await supabase.from('users').select('*').eq('id', id)

// Auth
const { user } = await supabase.auth.signUp({ email, password })

// Storage
const { data } = await supabase.storage.from('avatars').upload('photo.jpg', file)

// Real-time
supabase.channel('room').on('broadcast', { event: 'message' }, handler).subscribe()

One SDK for database, auth, storage, and real-time. Fastest way to build a full-stack app.

PlanetScale

Pure database. MySQL compatible. Connect with any MySQL client or ORM.

import { connect } from '@planetscale/database'
const conn = connect({ url: process.env.DATABASE_URL })
const { rows } = await conn.execute('SELECT * FROM users WHERE id = ?', [id])

When to Use Each

Choose Neon When

• Want serverless Postgres (scale to zero)
• Need database branching for preview deployments
• Using Drizzle/Prisma and want pure Postgres
• Budget-conscious (free tier is generous)
• Building with Next.js + Vercel

Choose Supabase When

• Want an all-in-one backend (database + auth + storage)
• Building a full-stack app quickly
• Need real-time features
• Don't want to integrate 5 separate services
• Budget allows $25/mo for everything

Choose PlanetScale When

• Existing MySQL codebase
• Need zero-downtime schema migrations
• Schema branching workflow matters
• Large team with complex migration needs
• Vitess for horizontal scaling

The Honest Answer

Building a new SaaS with Next.js?

• Neon if you want just a database and will use Clerk for auth, R2 for storage
• Supabase if you want everything in one platform

Existing MySQL app?

• PlanetScale — the only real choice for managed MySQL

Hobby project?

• Neon — free tier with scale-to-zero costs literally $0

FAQ

Can I use Prisma/Drizzle with all three?

Yes. Neon and Supabase use Postgres (Prisma/Drizzle support). PlanetScale uses MySQL (Prisma supports, Drizzle supports).

Is PlanetScale still viable after removing the free tier?

PlanetScale removed their free tier in 2024. The paid plans are competitive but the free tier loss pushed many developers to Neon or Supabase.

Can Supabase replace Firebase?

Yes, for most use cases. Supabase offers database, auth, storage, real-time, and edge functions — everything Firebase does but with Postgres instead of Firestore.

Which has the best performance?

Comparable for most workloads. Neon and PlanetScale have slight advantages in cold-start scenarios. Supabase has no cold starts (always running).

Bottom Line

Neon for pure serverless Postgres with branching. Supabase for an all-in-one backend platform. PlanetScale for MySQL with zero-downtime migrations. Most developers starting fresh in 2026: Neon (database) + Clerk (auth) + R2 (storage), or Supabase for everything-in-one.
