Serving as a functional dbdiagram.io alternative and drawdb substitute, it allows you to construct a database schema diagram or a db diagram from scratch without needing direct access to your live database. The platform operates as a practical sql table visualizer and database diagram editor, enabling users to import schema definitions, edit tables, and export DDL scripts in their desired SQL dialect.
