Serverless Database Comparison: Neon vs PlanetScale vs Turso vs Supabase (2026)

Serverless databases scale to zero when idle and scale up automatically under load. No provisioning, no capacity planning, no paying for idle resources. Here's how the top options compare in 2026.

Neon: Serverless PostgreSQL

Neon is PostgreSQL with serverless superpowers: scale to zero, instant branching, and bottomless storage.

Strengths

• Full PostgreSQL. Extensions, full SQL, pg_vector for AI, PostGIS for geo — everything PostgreSQL offers.
• Instant branching. Copy-on-write database branches in milliseconds. Branch per PR, per feature, per test run.
• Scale to zero. Compute scales down to nothing when idle. Pay nothing for dev/staging databases that sit unused.
• Bottomless storage. Storage is separated from compute. Data stored in S3-compatible object storage.
• Serverless driver. HTTP and WebSocket connections for serverless/edge environments (no persistent TCP needed).

Weaknesses

• Cold start latency. Scaling from zero adds ~500ms-1s to the first query.
• Regional only. No global read replicas (data lives in one region).
• Compute-based pricing. Can be expensive for always-on workloads vs. traditional Postgres hosting.
• Newer platform. Less battle-tested than RDS or self-managed Postgres at extreme scale.

Pricing

• Free: 0.5 GB storage, 190 compute hours/month
• Launch: $19/month (10 GB, 300 compute hours)
• Scale: $69/month (50 GB, 750 compute hours)

Best For

PostgreSQL users who want serverless scaling and database branching. Excellent for Vercel/Next.js deployments.

PlanetScale: Serverless MySQL

PlanetScale brings Vitess (YouTube's MySQL scaling layer) to developers as a managed serverless database.

Strengths

• Vitess-powered. The same technology that scales YouTube's database. Proven at massive scale.
• Database branching. Branch schema changes, test in isolation, merge with deploy requests.
• Non-blocking schema changes. Alter tables without locking or downtime. Critical for production databases.
• Generous free tier. 5 GB storage on free plan.
• Boost (query caching). Automatic query caching at the edge for read-heavy workloads.

Weaknesses

• MySQL only. No PostgreSQL option. Some developers prefer PostgreSQL's features and ecosystem.
• No foreign keys (enforced). Vitess doesn't support enforced foreign key constraints. Referential integrity is application-level.
• Row-based pricing. Can be unpredictable for query-heavy workloads.
• Free tier removed and restored. Pricing changes have created uncertainty.

Pricing

• Hobby: Free (5 GB, 1B row reads/mo)
• Scaler: $29/month (10 GB, 100B reads)
• Enterprise: Custom

Best For

MySQL users who need non-blocking schema changes and battle-tested scalability. Great for large applications.

Turso: Edge SQLite

Turso distributes SQLite (via libSQL) globally. Your database lives at the edge, close to your users.

Strengths

• Global edge replicas. Read replicas in 30+ locations worldwide. Sub-10ms reads from anywhere.
• Embedded mode. Embed the database directly in your application process. Zero network latency for reads.
• SQLite compatible. Use SQLite's simple, well-understood SQL. Local development is just a SQLite file.
• Generous free tier. 9 GB total storage, 500 databases on the free plan.
• Multi-database. Create per-tenant databases easily. Each customer gets their own database.

Weaknesses

• SQLite limitations. No stored procedures, limited concurrent writes (single writer per database), fewer data types.
• Write latency. Writes go to the primary region and propagate to replicas. Not instant globally.
• Newer technology. libSQL is a fork of SQLite with extensions — less ecosystem than PostgreSQL/MySQL.
• Not ideal for complex queries. SQLite's query planner is simpler than PostgreSQL's.

Pricing

• Starter: Free (9 GB, 500 databases, 25B row reads)
• Scaler: $29/month (24 GB, 10K databases)
• Enterprise: Custom

Best For

Edge-first applications, multi-tenant architectures (database per tenant), and apps where read latency is critical.

Supabase: PostgreSQL Platform

Supabase isn't purely serverless (compute doesn't scale to zero), but it's the most full-featured PostgreSQL platform.

Strengths

• Full platform. Database + auth + storage + real-time + edge functions. Not just a database.
• PostgreSQL with everything. Extensions, RLS, full SQL, real-time subscriptions.
• Row-Level Security. Database-level access control. Critical for multi-tenant apps.
• Real-time. Subscribe to database changes via WebSocket.
• Generous free tier. 500 MB database, 1 GB storage, 2 GB bandwidth.

Weaknesses

• No scale to zero. Compute is always-on. You pay for provisioned compute even when idle.
• No branching. No database branching like Neon or PlanetScale.
• Connection pooling needed. Serverless environments require connection pooling (Supavisor).
• Scaling requires manual plan changes. Not truly auto-scaling compute.

Pricing

• Free: 500 MB database, 2 projects
• Pro: $25/month (8 GB, unlimited projects)
• Team: $599/month

Best For

Teams that want a full backend platform (not just a database). Best when you'll use auth, storage, and real-time alongside the database.

MySQL + massive scale + schema changes	PlanetScale
Edge-first + per-tenant databases	Turso

Fastest global reads	Turso (edge replicas)
Simplest migration from existing Postgres	Neon or Supabase

FAQ

Which is cheapest for a side project?

Turso (9 GB free) or PlanetScale (5 GB free) offer the most free storage. Neon's scale-to-zero means zero cost when not in use.

Can I use Prisma/Drizzle with all of these?

Yes. All four work with Prisma and Drizzle ORM. Turso requires the libSQL adapter.

Which is best for Vercel/Next.js?

Neon has the tightest Vercel integration (Vercel Postgres IS Neon). Supabase and PlanetScale also integrate well.

Do I need a serverless database?

If you're on serverless infrastructure (Vercel, Cloudflare Workers), yes — traditional connection-based databases don't work well with ephemeral compute. If you're on a persistent server, a regular managed database (RDS, Cloud SQL) may be simpler.

The Verdict

• Neon for PostgreSQL with serverless scaling and branching. The default choice for modern Postgres.
• PlanetScale for MySQL at scale with zero-downtime schema changes.
• Turso for edge-first apps and multi-tenant architectures.
• Supabase for a complete backend platform, not just a database.

For most new projects in 2026, Neon is the best serverless database. It gives you full PostgreSQL with the serverless benefits (scale to zero, branching) that modern development demands.
