Open-source database diagram editor with AI-generated ER diagrams
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.
Describe a database idea in plain language and get a fully editable, optimized ER diagram that you can refine and export straight to SQL.
Export clean DDL scripts in your preferred SQL dialect or download diagrams as images and embeddable previews for documentation.
On Cloud plans, diagrams stay in sync with the live database automatically, with change logs and version history to track every schema drift.
