Modelio

Modelio is a comprehensive software application written in Java that facilitates an approachable UML modeling environment backed by a wide range of models and diagrams. Aside from Java, it doesn't require installation.

You can drop the program files in any part of the disk and just click the executable to launch Modelio. Another possibility is to save it to a pen drive or other removable storage unit, in order to run it on any PC effortlessly. Plus, it doesn't modify Windows registry settings.

The interface is comfortable and looks professional. You can immediately start a project, whether it's Java-based or not, and fill it with a numerous range of different stereotypes, such as class diagrams, data flow, connectors, constraints, extension points, events, interactions, control nodes, and components. It's possible to assign Explorer icons and diagram images.

The software program lets you edit elements when it comes to UML, audit, notes and constraints, configure program options regarding general and storage information, work models, libraries, modules, audit, and URLs, manage catalogs with modules and macros, customize all diagram styles, as well as view outlines, audit data, elements, scripts, the link editor, diagrams and symbols, together with notes and constraints.

Modelio is certainly an advanced Windows app for experienced users who want to work with UML diagrams, such as Computer Science students. Its response time is not that great, unfortunately. We've noticed that it takes a while to execute simple commands, like loading a panel with settings.

On top of that, Modelio needs an impressive amount of system memory to work properly. Nevertheless, you can test it for yourself and find out if it satisfies your preferences when it comes to an advanced and reliable UML diagram editor.
