PlanetScale vs Turso vs Neon (2026): Best Serverless Database?

Serverless databases promise zero-downtime scaling, branching workflows, and pay-per-use pricing. PlanetScale, Turso, and Neon each take a different approach — MySQL, SQLite, and PostgreSQL respectively. Here's which serverless database fits your stack.

Quick Comparison

PlanetScale	Turso	Neon
Engine	MySQL (Vitess)	SQLite (libSQL)
Free tier	5GB storage, 1B row reads	9GB storage, 1B row reads
Branching	Excellent (database branches = git branches)	No branching (replicas instead)
Edge	Limited	Excellent (25+ locations, embedded replicas)
Scale to zero	Yes (sleeps after inactivity)	N/A (SQLite is always ready)
Pricing model	Rows read + storage	Rows read + storage

PlanetScale — Git Workflows for Databases

PlanetScale is built on Vitess (YouTube's MySQL scaling layer). Its killer feature: database branching. Create a branch off your production schema, make changes, open a deploy request. Schema changes are automatically checked for compatibility before merging. This eliminates "works on my machine" database issues.

Best for: Teams that want database branching (schema as code), MySQL-compatible workloads, serverless apps with variable traffic.

Weak spot: MySQL engine (not Postgres — though many prefer Postgres). No edge deployment. Foreign key constraints are disabled by default (Vitess limitation).

Turso — SQLite at the Edge

Turso extends SQLite (via libSQL fork) to the edge. Your database is replicated across 25+ locations, and reads are served from the nearest replica. It's the best option for read-heavy, globally-distributed apps. SQLite compatibility means you can run the same DB locally during development.

Best for: Read-heavy apps, globally-distributed users, projects that want SQLite simplicity, edge computing (Cloudflare Workers, Vercel Edge).

Weak spot: SQLite engine (not full Postgres — limited extensions, no stored procedures). Single-primary writes (eventually consistent reads). No branching.

Neon — PostgreSQL, Serverless-Native

Neon makes PostgreSQL serverless: auto-suspend (scale to zero), instant copy-on-write branching, and a generous free tier. It's the closest to "Heroku Postgres but serverless." The branching model is excellent for preview environments — every PR gets its own database branch.

Best for: PostgreSQL workloads, preview/development database branching, serverless apps, teams that want the full Postgres feature set.

Weak spot: Smaller free compute (100 hours). Edge network is smaller than Turso's. Suspend/resume latency impacts cold starts.

Decision Matrix

Scenario	Best Serverless DB
PostgreSQL app, full feature set	Neon
Edge-heavy, globally distributed	Turso
Database branching workflow	PlanetScale (MySQL) or Neon (Postgres)
SQLite at the edge	Turso
Most generous free tier	PlanetScale or Turso

Bottom line: Neon for Postgres-first projects. Turso for edge/global SQLite. PlanetScale for MySQL workflows with database branching. All three have excellent free tiers — start there and scale when you need to. See also: Database Engine Comparison and Supabase vs Firebase vs Neon.
