About DB Planner
Designing and modifying complex database schemas across teams is often slowed down by clunky diagram tools and disconnected SQL scripts.
DB Planner is a collaborative database design and diagramming tool. It converts DBML or imported SQL DDL from PostgreSQL, MySQL, and SQL Server into interactive entity-relationship diagrams and Mermaid diagrams on a shared canvas.
Teams can organize modular schemas across multiple files, edit with a syntax-highlighted code editor, and collaborate in real time. It also supports exporting designs as SQL, DBML, or C# models, and includes Model Context Protocol integration for AI agents.
