Databases

Choose the database independently from the application runtime where supported. For example, a Cloudflare Worker or Hetzner application can both use Neon Postgres.

Choose a database

Database	Engine	Connection path	Setup
AWS RDS / Aurora	Postgres or MySQL	VPC connection; Data API on supported configurations	RDS & Aurora · Aurora + Drizzle
Aurora DSQL	Distributed SQL with Postgres wire compatibility	IAM-authenticated connection	DSQL + Drizzle
Cloudflare D1	SQLite	Native Worker binding	D1 + Drizzle
Durable Object storage	SQLite per named object	Instance storage	Durable Objects
Fly Managed Postgres	Postgres	Private connection from a Fly Service	Managed Postgres
Neon	Postgres	Direct or pooled URL; Hyperdrive from Workers	Neon branches · Connections
PlanetScale Postgres	Postgres	Role connection URL; Hyperdrive from Workers	PlanetScale Postgres
PlanetScale Vitess	MySQL	Password connection URL; Hyperdrive from Workers	PlanetScale MySQL
Prisma Postgres	Postgres	Database connection URL	Prisma Postgres
Railway Postgres	Postgres	Private service URL or public TCP proxy	Railway Postgres
Railway MySQL	MySQL	Private service URL or public TCP proxy	Railway MySQL

Hyperdrive pools connections to a database; it is not a database itself. The Hetzner guide hosts the application on Hetzner and the database on Neon.

Choose a client

Engine	Typed schema queries	Raw SQL
Postgres	Drizzle.Postgres · Prisma ORM	SQL.Postgres
MySQL	Drizzle.MySQL	SQL.MySQL
D1	Drizzle.D1	SQL.D1
Durable Objects	Drizzle.DurableObject	Instance SQL

Prisma ORM v8 requires PostgreSQL 17+. Aurora DSQL has its own authentication and SQL constraints; Postgres wire compatibility does not establish Prisma support or support for every PostgreSQL feature.

Commit migration files

pnpm exec drizzle-kit generate
git add src/schema.ts drizzle.config.ts drizzle
git diff --cached
git commit -m "Add schema migration"

This example uses out: "./drizzle"; use the output directory configured by your generator and apply committed SQL through the selected database’s migration workflow. Private databases require a runner with network access.
