ChartDB Overview
ChartDB is a powerful and intuitive tool designed to transform complex database schemas into clear, interactive, and shareable Entity-Relationship (ER) diagrams in seconds. Built by developers for developers, it addresses the common pain point of understanding and documenting database structures. With both a user-friendly cloud platform and a popular open-source, self-hosted option, ChartDB caters to individual developers, growing teams, and enterprises focused on security and customization.
The core of ChartDB is its simplicity and speed. Users can import their entire database schema with a single, pre-written query, eliminating the need for direct database access credentials. This process generates a beautiful, editable diagram almost instantly. The platform's AI Diagram Assistant elevates the experience by intelligently analyzing the schema to suggest improvements, find missing relationships, recommend foreign keys, and identify potential optimizations like missing indexes, helping teams build more robust and efficient databases.
How to use ChartDB
Using ChartDB is a straightforward, three-step process: Import, Edit, and Export.
- Import Instantly: Select your database type (e.g., PostgreSQL, MySQL, SQL Server). ChartDB provides a single, safe query to run against your database. This query fetches only the schema information (table names, columns, types, relationships) without accessing any sensitive data. Paste the query result into ChartDB to instantly generate your diagram.
- Edit & Collaborate: Once the diagram is generated, you can visually edit it. Create, manage, or delete tables and relationships using the advanced editor. Invite teammates to view and edit the diagram in real-time, ensuring everyone is on the same page. Use the AI Assistant by clicking “Ask AI” to get actionable suggestions for improving your schema.
- Sync & Export: Keep your diagram up-to-date with the Auto-Sync feature, which automatically reflects changes from your live database. When you're ready, export your diagram as a high-resolution image for documentation or presentations, or generate clean DDL SQL scripts to apply the changes back to your database. You can also share a public link to your diagram.
