Use Of The Tool

Free ER Diagram is provided as a free browser-based tool for creating database diagrams from SQL DDL. You are responsible for reviewing generated diagrams before using them in production documentation or design decisions.

No Account Required

The tool does not require registration. Any history or settings saved by the application are stored in your browser unless you export or share them.

Content And Examples

Articles, sample schemas, and generated examples are provided for educational and documentation purposes. They may need adaptation for your own database engine, security requirements, and business rules.

The site may change, add, or remove features over time. We try to keep the tool reliable, but it is provided without a guaranteed service level.
