In which tools do you draw ER diagrams (not in email)?

For creating ER diagrams, I used specialized tools such as:

• draw.io — a free online editor supporting ER diagram creation.
• dbdiagram.io — a convenient web service for quick diagram creation based on simple DSL.
• Microsoft Visio — a powerful tool for creating various diagrams, including ER.
• MySQL Workbench — if working with MySQL, I used the built-in ER diagram editor.

The choice of tool depends on the project requirements and team preferences. The main thing is that the diagrams are understandable and easy to update.
