UMLGraph - Automated Drawing of UML Diagrams

•    Java

---

UMLGraph allows the declarative specification and drawing of UML class and sequence diagrams. The current features are part of an ongoing effort aiming to provide support for all types UML diagrams. Running the UmlGraph doclet on the specification will generate a Graphviz diagram specification that can be automatically processed to create Postscript, GIF, SVG, JPEG, fig, or Framemaker drawings.

jdl-studio - JDL Studio is an online JHipster Domain Language visual editor

•    Javascript

---

Hello, this is JDL-Studio, an online tool for drawing UML diagrams for JHipster based on the JDL syntax. It tries to keep its syntax visually as close as possible to the generated UML diagram without resorting to ASCII drawings. The JDL-Studio web application is a simple editor with a live preview. It is purely client side and changes are saved to the browser's localStorage, so your diagram should be here the next time, (but no guarantees).

Dia - Visio alternative

•    GTK+

---

Dia is inspired by the commercial Windows program Visio, though more geared towards informal diagrams for casual use. It can be used to draw many different kinds of diagrams. It currently has special objects to help draw entity relationship diagrams, UML diagrams, flowcharts, network diagrams, and many other diagrams. It is also possible to add support for new shapes by writing simple XML files, using a subset of SVG to draw the shape.

UML-Designer - OpenSource (EPL licensed) UML2 Graphical Modelers (Class, Composite, State, Activity, Sequence

•    Java

---

UML Designer provides a set of common diagrams to work with UML 2.5 models. The intent is to provide an easy way to make the transition from UML to domain specific modeling. This way users can continue to manipulate legacy UML models and start working with DSL. Users can even re-use the provided representations and work in a total transparence on both UML and DSL models at the same time. These plugins are released under the EPL Open-Source License.
