UMLet is a free, open-source Java-based UML tool designed for teaching the Unified Modeling Language and for quickly creating UML diagrams. UMLet has a simple interface that uses text formatting codes to modify the basic shapes with decorations and annotations, so there is no forest of icons or parameter list dialogs in the user’s way. UMLet is a free open source UML modelling tool with a very simple user interface that’s easy for beginners to use. The difference between UMLet and other sequence diagram tools is that it allows you to modify diagrams using a text input tool instead of pop-up dialogs.
