PlantUml is a handy and reliable application that gives you the ability to design UML diagrams using a description language. The java based utility sports a clean, straightforward and intuitive layout that doesn’t have many configuration settings to play around with, making it relatively easy to learn to navigate and use.

With PlantUml, you can either insert your description language in the dedicated pane or instead opt to import data from one of the supported file formats. It also gives you the opportunity to create class, activity, sequence, component, state, and more.

And since it’s portable you won’t need to worry about leaving any traces of the application on your Windows registry; it can also be loaded onto a USB stick or other external drive and taken with you anywhere you go.


- Lets you choose to insert your own descriptive language or instead opt to import data from a supported file format (Java, HTML, C, CPP, Y, plain text, etc.).
- Lets you create sequence, use case, class, activity, component, state, or object diagrams.
- Lets you save your generated diagram to PNG or SVG file format whenever you’re finished.
- An intuitive layout that can be used by anyone that has a general knowledge of how this type of program works.
- Completely portable – Can be taken with you anywhere and used without leaving any traces on the Windows registry.
- Java based.


Please note that you must have Java installed on your computer in order for PlantUml to function properly on your system.
