Dbdiagram

A code-based tool for drawing entity-relationship diagrams and data lineage maps that generates visuals from DBML and SQL imports to design and document database schemas. It is for developers, data analysts, and product, data and engineering teams that need to model databases. It is delivered as a web-based SaaS application with a free tier that uses a write-code-to-visualize approach instead of manual drag-and-drop diagramming.
