Most database design tools are either expensive, desktop-only, or require an account just to get started. SQL Designer runs in your browser, free, and gets you from idea to schema in seconds.

- Bidirectional SQL — import existing SQL to visualize it, or export clean
CREATEstatements from your diagram - MySQL & PostgreSQL — full support for both dialects
- Open source — read the code, report bugs, suggest features
- Visual diagram editor — design schemas on an interactive canvas with drag-and-drop support
- Table & column management — create, rename, and delete tables and columns inline
- Relationship visualization — connect tables with relationship lines using crow's foot notation
- Support for MySQL, PostgreSQL, SQLite, Oracle, SQL Server, and MS Access — choose your target database type per diagram
