This approach keeps developers in their natural coding workflow while producing visual documentation that's essential for understanding database structures.
The tool stands out with its real-time collaboration features, allowing entire teams to work on diagrams simultaneously like Google Docs.

Additional practical features include SQL import/export capabilities, version history tracking, and flexible export options to PDF, PNG, or embeddable formats for documentation.
