Desktopfree

JetUML is a free, open-source desktop UML editor built for quickly sketching software design diagrams with minimal setup. Diagrams can be exported to common image formats or copied to the clipboard for use in other tools. It suits developers who want a lightweight way to sketch a UML diagram before writing code, rather than opening a heavyweight commercial modeling tool.
