UMLet is a free, open-source UML tool with a simple user interface: draw UML diagrams fast, build sequence and activity diagrams from plain text, export diagrams to eps, pdf, jpg, svg, and clipboard, share diagrams using Eclipse, and create new, custom UML elements.
UMLet’s main user interface provides three panels: the diagram, the palette, and the property panel. The diagram panel displays the diagram and lets the user modify the UML elements’ location; the palette panel lists the available elements; and the property panel lets users view and modify element properties.
UMLet runs stand-alone or as Eclipse plug-in on Windows, OS X and Linux.
Key Features
- Supports a variety of UML diagram types: class diagrams, use case diagrams, sequence diagrams, state diagrams, deployment diagrams, and activity diagrams.
- Custom elements – UMLet text-based approach is mainly aimed at fast UML sketching. Advanced users, however, can also create new types of UML elements within UMLet at run-time—custom elements. An element’s look can be modified at run-time by changing a few lines of Java code; UMLet then compiles the new element’s code on the fly. Without leaving UMLet, users can therefore create and add new element types to their diagrams.
- Share diagrams using Eclipse.
- Sticking polygon.
- Show grid.
- Export diagrams to BMP, EPS, GIF, JPG, PDF, PNG, and SVG formats.
