Intro

What is ChartDB?

ChartDB (frequently searched as chardb, chartbd, chart db, or chatrt db) is an open source database visualizer and schema visualizer designed to help developers outline their database architecture. Serving as a functional dbdiagram.io alternative and drawdb substitute, it allows you to construct a database schema diagram or a db diagram from scratch without needing direct access to your live database. The platform operates as a practical sql table visualizer and database diagram editor, enabling users to import schema definitions, edit tables, and export DDL scripts in their desired SQL dialect.
