Neon vs PlanetScale vs Supabase: Serverless Databases in 2026

Two years ago, setting up a production database meant provisioning an RDS instance, choosing an instance size (and paying for it 24/7 whether you used it or not), configuring backups, managing connection pooling, and hoping you picked the right size. Serverless databases changed all of that.

Neon, PlanetScale, and Supabase offer databases that scale automatically, charge based on usage, and require zero infrastructure management. For startups, this means your database costs $0 to $5/month during development and scales smoothly to $50 to $500/month in production without re-architecting anything.

But these three products are fundamentally different under the hood. Neon is serverless PostgreSQL with database branching. PlanetScale is serverless MySQL with a Git-like schema change workflow. Supabase is PostgreSQL with a full backend-as-a-service layer (auth, storage, real-time, edge functions). Choosing between them is not just a database decision. It is an architecture decision.

Neon is the closest thing to "just PostgreSQL, but serverless." It runs standard PostgreSQL (version 16 as of 2026) with a custom storage layer that separates compute from storage, enabling instant branching, autoscaling, and scale-to-zero.

Key Features

• Database branching: Create a full copy of your database (schema and data) in seconds. Use branches for preview deployments, testing migrations, or giving each developer their own database. This is Neon's killer feature.
• Scale to zero: Compute shuts down after 5 minutes of inactivity (configurable). You pay nothing for idle databases. Cold start takes 500ms to 2 seconds.
• Autoscaling: Compute scales up and down automatically based on query load. No instance size selection needed.
• Full PostgreSQL compatibility: Extensions (pgvector, PostGIS, pg_trgm), foreign data wrappers, and all standard PostgreSQL features work.

Pricing

Free tier: 0.5 GB storage, 10 branches, 1 compute. Launch plan: $19/month for 10 GB storage, 50 branches, autoscaling. Scale plan: $69/month for 50 GB, unlimited branches. Additional compute billed at $0.16/compute-hour. Storage beyond included amount at $0.024/GB/month.

Best For

Teams that want standard PostgreSQL without managing infrastructure. Projects using ORMs like Prisma, Drizzle, or TypeORM that just need a PostgreSQL connection string. Preview environments and CI/CD workflows that benefit from database branching. For a deeper comparison of database options, our PostgreSQL vs MongoDB guide covers the relational vs document database decision.

PlanetScale is built on Vitess, the same technology that powers YouTube's databases. It offers serverless MySQL with a unique approach to schema changes: database branches and deploy requests, which work like Git branches and pull requests for your database schema.

Key Features

• Non-blocking schema changes: PlanetScale's deploy request workflow lets you make schema changes without locking tables or causing downtime. Changes are reviewed, tested on a branch, and deployed atomically. This is critical for production databases with heavy traffic.
• Connection pooling built-in: PlanetScale handles connection pooling automatically through their proxy layer. No need for PgBouncer or similar tools.
• Read replicas: Automatic read replicas in multiple regions for global applications.
• Vitess-powered sharding: For databases that need to scale beyond a single node, PlanetScale handles horizontal sharding automatically. Most startups never need this, but it is reassuring to know the ceiling is very high.

Pricing

Free tier was removed in 2024, then partially restored. Scaler plan: $39/month for 10 GB storage, 1 billion row reads/month, 10 million row writes/month. Scaler Pro: $99/month with more resources and production support. Usage beyond included amounts is billed per-row-read and per-row-write.

Best For

Teams that prefer MySQL. Applications with frequent schema changes that need zero-downtime migrations. High-traffic applications that might need horizontal sharding in the future. Teams coming from a MySQL background (Laravel, Rails, Django projects that historically use MySQL).

Trade-offs

PlanetScale does not support foreign keys at the database level (a Vitess limitation). This is a dealbreaker for some teams and a non-issue for others who enforce referential integrity at the application layer. PlanetScale also does not support some MySQL features like stored procedures and triggers. If your application relies on these, look elsewhere.

Supabase is not just a database. It is a complete backend-as-a-service platform built on PostgreSQL. Database, authentication, file storage, real-time subscriptions, edge functions, and vector embeddings are all included in one platform.

Key Features

• PostgreSQL with auto-generated APIs: Supabase automatically generates REST and GraphQL APIs from your database schema using PostgREST. Create a table, and you immediately have CRUD endpoints with filtering, pagination, and relations.
• Built-in auth: Email/password, OAuth (Google, GitHub, Apple, etc.), magic links, and phone auth. No need for a separate auth provider.
• Real-time subscriptions: Subscribe to database changes over WebSockets. When a row is inserted, updated, or deleted, connected clients receive the change instantly. Powered by PostgreSQL's logical replication.
• Storage: S3-compatible file storage with built-in image transformations (resize, crop, convert formats).
• Edge Functions: Deno-based serverless functions for custom backend logic.
• Vector support: pgvector extension is pre-installed for AI/ML embedding storage and similarity search.

Pricing

Free tier: 500 MB database, 1 GB file storage, 50,000 MAU auth, 2 edge function invocations/second. Pro: $25/month with 8 GB database, 100 GB storage, 100,000 MAU. Team: $599/month with priority support and SOC 2 compliance. Additional usage billed per-resource.

Best For

Startups that want to minimize their backend stack. Projects where real-time features are important (chat, notifications, collaborative editing). Teams using vibe coding tools like Lovable (which has native Supabase integration). Projects that need auth, storage, and database in one bill. For a detailed comparison with its main competitor, see our Supabase vs Firebase guide.

Here is how they compare on the metrics that matter for production applications:

Query Performance

All three deliver sub-10ms query latency for simple operations when the compute is warm. Neon and Supabase run standard PostgreSQL, so query performance is identical for the same hardware configuration. PlanetScale adds a small overhead from the Vitess proxy layer (1 to 2ms per query) but gains automatic connection pooling. Cold start latency matters for scale-to-zero: Neon takes 500ms to 2 seconds, while Supabase and PlanetScale keep always-on instances on paid plans.

Connection Handling

Serverless functions (Vercel, AWS Lambda, Cloudflare Workers) create many short-lived connections that can overwhelm traditional databases. Neon includes a built-in connection pooler (powered by PgBouncer). PlanetScale handles connections through their Vitess proxy. Supabase offers Supavisor for connection pooling. All three handle the serverless connection problem, but Neon and PlanetScale do it more seamlessly.

Developer Experience

Supabase has the best dashboard for non-SQL users (table editor, SQL editor, auth management, storage browser all in one UI). Neon has the cleanest PostgreSQL-focused experience. PlanetScale's deploy request workflow is excellent for teams that want database schema changes to go through code review.

ORM Compatibility

Neon and Supabase work with every PostgreSQL ORM (Prisma, Drizzle, TypeORM, Sequelize, Knex). PlanetScale works with MySQL ORMs (Prisma for MySQL, TypeORM, Sequelize). Drizzle ORM supports all three with different drivers. If you are using Prisma (the most popular TypeScript ORM), all three work, but Prisma with PostgreSQL gives you more features than Prisma with MySQL.

Choosing a database is a long-term commitment. Here are the practical considerations beyond day-one features:

Data Portability

Neon and Supabase run standard PostgreSQL. You can pg_dump your data and move to any other PostgreSQL host (RDS, Cloud SQL, self-hosted) at any time. PlanetScale runs MySQL, so you can mysqldump and move to any MySQL host. All three provide reasonable data portability, but Supabase's additional services (auth, storage, real-time) create soft lock-in because migrating those features requires more work.

Scaling Ceiling

Neon scales vertically up to 7 compute units (roughly equivalent to an r5.xlarge RDS instance). For most startups, this handles millions of rows comfortably. PlanetScale scales horizontally via Vitess sharding, giving it the highest theoretical ceiling. Supabase scales vertically with the option to add read replicas on the Team plan. For guidance on when and how to scale your database, our database scaling guide covers the strategies in detail.

Backup and Recovery

Neon provides point-in-time recovery down to the second using its storage architecture. PlanetScale offers daily automated backups with point-in-time recovery on paid plans. Supabase provides daily backups on the Pro plan and point-in-time recovery on the Team plan.

Compliance

Supabase offers SOC 2 compliance on the Team plan ($599/month). Neon offers SOC 2 on the Scale plan ($69/month). PlanetScale offers SOC 2 on the Scaler Pro plan ($99/month). If you need HIPAA compliance, Supabase offers it on Enterprise plans. Neon and PlanetScale do not currently offer HIPAA BAAs.

After using all three on production projects, here is our straightforward advice:

Choose Neon If

You want PostgreSQL and nothing else. You value database branching for development workflows. You are using Prisma or Drizzle and just need a connection string. Your application handles its own auth, storage, and real-time features. Neon is the purest serverless PostgreSQL experience available.

Choose PlanetScale If

You prefer MySQL or your team has MySQL expertise. You need zero-downtime schema migrations for a high-traffic application. You anticipate needing horizontal sharding at scale. You are running a Laravel or Rails application. PlanetScale is the best serverless MySQL option.

Choose Supabase If

You want to ship fast with minimal backend code. You need auth, storage, and real-time out of the box. You are a solo founder or small team building an MVP. You are using Lovable, Bolt, or another AI app builder with Supabase integration. Supabase gives you the most functionality per dollar and per engineering hour.

Cost Comparison at Scale

For a typical SaaS application with 10 GB of data, 50,000 MAU, and moderate query load: Neon costs roughly $69/month (Scale plan). PlanetScale costs roughly $99/month (Scaler Pro). Supabase costs roughly $25/month (Pro plan) but replaces $50 to $100+ in auth and storage services you would need separately with Neon or PlanetScale. Total cost of ownership favors Supabase for teams that use its full feature set.
