ChartDB Cloud

What is ChartDB Cloud?

ChartDB Cloud is a web-based tool for generating entity-relationship (ER) diagrams from database schemas. Users can create visual representations of their database structure by providing query results, SQL statements, or DBML code—without requiring direct database access or credentials. The platform was developed by the creators of ChartDB, an open-source project that gained significant adoption over the past year. The tool serves database administrators, developers, and data architects who need to document, visualize, or understand database structures quickly. It eliminates the friction of traditional ER diagram creation, which often requires manual input or specialized database connection permissions. The cloud version builds on the foundation of the open-source offering, providing accessibility through a browser interface. Key features include support for multiple input formats (SQL, DBML, and query results), making it adaptable to different workflows and database systems. The diagram generation is automated, reducing the time needed to create comprehensive schema documentation. ChartDB Cloud operates on an open-source model, maintaining the accessibility that made the original project popular while offering a hosted solution that removes installation and setup requirements. It targets users who prioritize simplicity and security—allowing schema visualization without exposing sensitive database credentials.
