How to use this tool

Build UML diagrams from text directly in your browser: sequences, classes, activities, and other diagrams. Source is on the left; the result and style controls are on the right.

Steps

  1. Write your PlantUML diagram in the editor on the left.
  2. Choose a style on the right. Arifmera is the default, followed by standard PlantUML themes.
  3. Pan by dragging with the left mouse button or using the wheel. Ctrl / Cmd and the wheel zoom. Choose SVG, PNG, or ASCII and download the result.

Useful for

  • Architecture documentation
  • Service interaction diagrams
  • Class and process diagrams

Limits and accuracy

  • ASCII preserves a simplified diagram with text labels, without colors or fonts.
  • One diagram at a time, up to 50,000 characters. External !include directives and additional sprite libraries are unsupported.

Privacy

Rendering runs in your browser. Source is not sent to a server or saved by the site.
