PlanetScale vs Neon vs Turso

Comparison of three serverless Postgres/SQLite platforms: PlanetScale (MySQL Vitess), Neon (Postgres with branching), Turso (libSQL/SQLite at the edge).

Cloud ComparisonIntermediate

Why

These 'serverless database' platforms offer a connection string, branching/preview DBs, and scale-to-zero pricing. PlanetScale is MySQL (Vitess, no FK constraints); Neon is full Postgres with copy-on-write branches; Turso is SQLite-based (libSQL) with replicas at the edge for ultra-low latency reads. the cloud infrastructure market reached $330B in 2024, growing 22% year-over-year (Synergy Research).

The top 3 providers (AWS, Azure, GCP) account for 68% of public cloud, but tier-2 providers (Cloudflare, DigitalOcean, Railway) win on developer experience and price transparency.

When

Use Neon for full Postgres features (FK, extensions, triggers) and branching. Use PlanetScale for MySQL workloads or extreme write scale (Vitess shards).

Use Turso for read-heavy edge apps (SQLite replicas near users) and embedded/local-first apps. All have a free tier.

How

1. Create a database on the platform's CLI or web. 2. Get a connection string (Neon/Turso) or a branch + connection (PlanetScale). 3. Connect with any Postgres/MySQL/SQLite client. 4. (Neon/PlanetScale) Create a branch for a preview env, apply migrations, merge. 5. (Turso) Create replicas in regions near your users. ```bash neonctl projects create mydb && neonctl branches create preview pscale database create mydb --branch main && pscale branch create preview mydb turso db create mydb && turso db replicate mydb fra nrt ```

Example

Neon branching for a preview deploy — create a branch, run migrations, point the preview app at it, then merge or discard: ```bash # create a preview branch from main neonctl branches create preview --parent main export DATABASE_URL="postgres://...preview..." # run migrations on the branch npx prisma migrate deploy # deploy preview app with this DATABASE_URL vercel --prod --env DATABASE_URL=$DATABASE_URL # after review: merge into main (fast, copy-on-write) neonctl branches merge preview --parent main ``` Turso embedded replica (local-first, syncs to edge): ```ts import { createClient } from "@libsql/client"; const client = createClient({ url: "file:local.db", syncUrl: process.env.TURSO_URL!, authToken: process.env.TURSO_TOKEN! }); await client.sync(); // pull latest from edge ```

Common Problems

⚠PlanetScale has no foreign key constraints (Vitess limitation) — enforce referential integrity in app code or use Neon (full Postgres) if you need FKs.
⚠Neon compute autosuspend causes cold starts — the free tier suspends after idle; use a connection pooler (PgBouncer) and accept ~300ms cold start, or keep it warm with a cron ping.
⚠Turso SQLite lacks some Postgres features (stored procedures, advanced types) — if you need them, use Neon; Turso is best for simple schemas and read-heavy edge.

Best Practices

✓Use database branching (Neon/PlanetScale) for preview environments — each PR gets an isolated DB with the production schema, merged on merge.
✓For Turso, create replicas in your top user regions so reads hit a local SQLite (sub-10ms); writes go to the primary and sync back.
✓Use a connection pooler (PgBouncer for Neon, Hyperdrive for PlanetScale) to avoid exhausting connections from serverless functions.

FAQ
