Atlas

Atlas takes a declarative approach to database migrations. Define your desired schema state, and Atlas computes the diff and generates the migration SQL. Supports PostgreSQL , MySQL, SQLite , SQL Server, and ClickHouse .

Works as a standalone CLI or integrates into existing workflows alongside ORMs like Drizzle and Prisma . Schema-as-code definitions can live in HCL, SQL, or be loaded from your ORM's schema. Built-in linting catches destructive changes before they hit production.
