ChartDB is a free, open-source database diagram editor and data modeling tool, positioned as "visualize and design your database structure with a single query." Its core goal is to help engineers quickly understand existing databases, design new architectures, and generate executable DDL scripts.
In terms of use, ChartDB is mainly used for database schema visualization, ER diagram drawing, data modeling, team collaboration, and database migration. Users can obtain diagrams without direct access to the database, and the import process can be completed in about 15 seconds.
Main capabilities:
- Database structure diagrams and the import/edit/export workflow. It provides a single query for each database to obtain the complete schema, and supports exporting diagrams as SQL (DDL) scripts or images for documentation.
- AI ER diagram generator. It can turn database ideas into fully editable and optimized ER diagrams, and generate clean DDL scripts in the user's preferred SQL dialect.
- Automatic synchronization. Diagrams can automatically stay in sync with the live database and track every schema change, allowing users to view differences and version history.
- Real-time collaboration. Team members can be invited to view and edit diagrams in real time.
- Embeddable diagrams. It generates customizable, scalable, embeddable database structure documentation suitable for platforms such as Notion, Miro, and Confluence.
- Advanced query editor. It supports undo, redo, copy, paste, duplicate, as well as adding tables, subject areas, and notes, and managing tables and relationships.
- Database support. Full support for MySQL, MariaDB, PostgreSQL, Microsoft SQL Server, and SQLite.
- Other features. These include an SQL syntax checker, SQL query explainer, dialect converter, open-source ERD, automatic saving of changes, and quick start with pre-designed examples.
How to use it: Users can choose cloud or self-hosted. The cloud option allows instant database visualization in the browser, suitable for ease of use and team accessibility; the self-hosted option (with over 20,000 GitHub stars) gives full control over data and the deployment environment, suitable for security and customization needs. ChartDB does not require a credit card, and diagrams can be generated without database access permissions.
