StarUML is an advanced software modeler used for agile and concise modeling.

Functional features:

1. UML 2

Compatible with UML 2. x standard metamodel and diagrams: classes, objects, use cases, components, deployment, composite structures, sequences, communication, state diagrams, activities, timing, interaction overflow, information flow, and configuration diagrams.

1. SysML support

Support modeling using SysML diagrams: requirements, block definitions, internal blocks, and parameter diagrams.

1. Additional image

Support the creation of entity relationship diagrams (ERDs), data flow diagrams (DFDs), and flowcharts.

1. Cross platform support

Use the same UX on multiple platforms including MacOS, Windows, and Linux.

1. Automatic update

StarUML checks for the latest updates and automatically installs for MacOS and Windows.

1. MacBook Touch Bar

1. Retinal display support

Supports retina (high DPI) display. All charts, text, and icons are very clear and can be exported as High DPI images (PNG and JPEG).

1. Promotion Manager

Easily discover and install third-party extensions. Many extensions are open source and hosted on Github. Split one and do it yourself.

1. Model driven development

Modeling data is stored in a very simple JSON format, so it can be easily used to generate custom code through user-defined templates (mdgen).

1. Rapid modeling

Support many shorthand tools in quick editing to immediately create elements and relationships, such as subclasses, support interfaces, etc.

1. The theme of darkness and light

Supports light and dark themes, so you can choose a more comfortable theme.

1. Command Panel

Command Palette allows searching and executing commands in StarUML and installed extensions.

1. Code Engineering

Support code generation and reverse engineering for major programming languages, including Java, C #, and C++, through open-source extensions.

1. Open API

Allow the use of HTML5, CSS3, JavaScript, Node.js modules and APIs to write your own extensions for menus, key mappings, dialog boxes, UI, metadata, preferences, and more.

1. Asynchronous model validation

Every time you save or open a model file, many model validation rules are defined and checked asynchronously.

1. Publish HTML document

Simply publish an HTML document to easily share models with other analysts, architects, and developers.

1. PDF export for clean printing

The chart can be exported as a PDF for clean printing, with printing options such as page layout and size.

1. Price reduction support

Use markdown syntax to edit document elements and support syntax highlighting and preview.
