DB Planner turns DBML into interactive ER diagrams and Mermaid into class diagrams and flowcharts, on one board your whole team edits in real time.
Import SQL from Postgres, MySQL, or MSSQL. Export C# models, SQL, DBML, Mermaid files, or export the board as an image.
There is also an MCP server, so your AI assistant can set up projects, edit schemas, and lay out the board for you.
Start on the free plan, no card needed. Pro is $5, which lets you create an org, and added seats are $5 after.
