DesignSQL is a bi-directional database schema editor where you can design in code or drag-and-drop visually — and both stay perfectly in sync. Describe your schema in plain English and the AI assistant writes the DBML for you. Version control, team collaboration, and SQL export built in.

Free online database schema designer & ER diagram tool — no sign-up needed. Drag and drop tables, define relationships, and export to SQL, Prisma, GORM, Laravel, and more. Supports PostgreSQL, MySQL, SQLite & MSSQL natively. Start locally for free. Go Pro for cloud sync & version history. Unlike dbdiagram.io or DrawSQL — DesignSQL takes you from diagram to deployable code, faster.
