Drizzle Schema Generator

Developer

Generate Drizzle ORM schema files for PostgreSQL, MySQL, or SQLite. Define tables, columns, relations, and indexes visually.

Quick Presets

import { pgTable, serial, varchar, timestamp } from 'drizzle-orm/pg-core'; export const users = pgTable('users', { id: serial('id').primaryKey(), name: varchar('name').notNull(), email: varchar('email').notNull().unique(), created_at: timestamp('created_at').notNull().defaultNow(), }); export type UsersInsert = typeof users.$inferInsert; export type UsersSelect = typeof users.$inferSelect;

About Drizzle ORM

Drizzle ORM is a lightweight, type-safe TypeScript ORM with zero dependencies. It provides a SQL-like query builder and schema-first approach.

  • Type-Safe - Full TypeScript inference from your schema definition
  • SQL-Like - Familiar SQL syntax with a type-safe query builder
  • Zero Dependencies - Lightweight and fast, no heavy runtime
  • Drizzle Kit - Automatic migration generation from schema changes

What is This Tool?

A Drizzle ORM schema generator creates TypeScript schema definitions for Drizzle ORM — a lightweight, type-safe ORM for PostgreSQL, MySQL, and SQLite. Define tables, columns, relations, and indexes with a visual editor and export production-ready Drizzle schema code.

Drizzle ORM uses a schema-as-code approach where TypeScript table definitions serve as both the schema definition and the type source. This ensures full type safety from database to application code, with zero runtime overhead and SQL-like query building.

Common Use Cases

New Database Design

Design database schemas visually and generate Drizzle table definitions with correct column types, defaults, and constraints.

Migration from SQL

Convert existing SQL CREATE TABLE statements to Drizzle schema definitions when adopting Drizzle ORM.

Rapid Prototyping

Quickly scaffold database schemas for new features with proper relations and indexes.

Team Onboarding

Generate example Drizzle schemas for learning the ORM's syntax and conventions.

Frequently Asked Questions

Which databases does Drizzle support?

PostgreSQL (pg, Neon, Supabase), MySQL (mysql2, PlanetScale), and SQLite (better-sqlite3, Turso, D1).

How does Drizzle compare to Prisma?

Drizzle is lighter, SQL-closer, and zero-abstraction. Prisma has its own query language and schema format. Drizzle uses TypeScript directly for schemas.

Are migrations generated?

Drizzle Kit (drizzle-kit) generates SQL migrations from schema changes. This tool generates the schema; drizzle-kit handles migrations.
