ChartDB

Open-source database diagram editor with AI-generated ER diagrams

One-query schema import

Paste a single read-only query result and ChartDB renders the whole schema as an ER diagram, with no direct database access or local agent required.

AI ER diagram generator

Describe a database idea in plain language and get a fully editable, optimized ER diagram that you can refine and export straight to SQL.

DDL and diagram export

Export clean DDL scripts in your preferred SQL dialect or download diagrams as images and embeddable previews for documentation.

Auto-sync and versioning

On Cloud plans, diagrams stay in sync with the live database automatically, with change logs and version history to track every schema drift.
