ChartDB is a free and open-source database schema diagram visualizer that enables users to design and visualize their database schemas using a single query. It's specifically built to assist developers and database administrators in creating and managing relationship diagrams with ease.

- Export SQL: Generate clean DDL scripts in your preferred SQL dialect.
- Team Collaboration: Real-time collaboration features for teams to view and edit diagrams together.
- AI Diagram Assistant: Use AI to assist in diagram creation and management.
- DBML Editor: Support for DBML (Database Markup Language) for defining and managing database schemas.
- Cloud and Self-Hosted Options: Offers both cloud-based and self-hosted deployment options.
