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 — 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

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.
