What tools do you use to draw UML diagrams?

The following tools are often used for drawing UML diagrams:

• Draw.io (diagrams.net) — a free web-based tool supporting UML.
• StarUML — a powerful desktop editor supporting various types of UML diagrams.
• PlantUML — a textual language for describing diagrams, which can be integrated into IDEs and CI.
• Visual Paradigm — a professional tool with extensive functionality.
• Enterprise Architect — a comprehensive modeling solution.

The choice depends on the tasks, convenience, and project requirements. For quick visualization, Draw.io is suitable, while for complex design, Enterprise Architect or Visual Paradigm are preferable.
