ChartDB is a database schema visualizer and entity-relationship diagramming platform designed to help developers understand, design, and document complex data architectures. It functions as a visual workspace where users can create and modify database schemas, define table attributes, and map foreign key relationships. By parsing database metadata or SQL scripts, the tool generates interactive diagrams that provide a clear overview of structural interdependencies and data associations.
The platform distinguishes itself through its focus on automated documentation and schema synchronization. It supports programmatic diagram generation and scheduled background tasks that refresh visual representations to reflect changes in the underlying database structure. This ensures that technical documentation remains aligned with the live schema, while features like dependency mapping and relationship cardinality visualization provide deeper insights into how data entities interact.
Beyond visualization, the tool facilitates schema portability by converting diagrams into standard database markup scripts, enabling version control and migration across different environments. Users can manage their workspace through automated layout engines, grid alignment, and filtering tools, or export diagrams as images for stakeholder sharing. The platform also supports embedding interactive diagrams into external documentation and offers containerized self-hosting options for teams requiring private infrastructure and data sovereignty.
