StarUML (the successor of an object oriented modelling software called Plastic) is a free and open-source UML (Unified Modeling Language) and SML (Systems Modeling Language) modeling tool for Windows, Mac and Linux platforms, developed by MKLabs from Korea, using Java. It allows users to draw various UML/SML diagrams (such as class diagrams, use case diagrams, class diagrams, sequence diagrams, state diagrams, activity diagrams, communication diagrams, module diagrams, deployment diagrams, composite structure diagrams, etc.).

StarUML has comprehensive functions, is easy to use, and has strong scalability. It supports complex modeling through MDA (Model Driven Architecture) and third-party plug-ins, supports various file formats such as XMI, JPG, JPEG, BMP, EMF, and WMF, and supports multiple GoF patterns and EJB patterns. In addition, it not only allows users to generate Java, C#, C++ and other coding programs through StarUML, but also reversely generates UML diagrams by reading Java, C#, C++ and other codes, so that users can make UML diagrams more conveniently and efficiently .

Although StarUML may not be suitable for beginners, StarUML still stands out among competitors such as ArgoUML, CASE Studio, and Rationale. Compared with PlantUML‘s way of using code to draw diagrams, StarUML’s drag-and-drop method is easier to use. In short, with its help, developers can design, create, conceptualize and code solutions.

// Key Features //

Feature	Description
UML 2	Compatible with UML 2.x standard metamodel and diagrams: Class, Object, Use Case, Component, Deployment, Composite Structure, Sequence, Communication, Statechart, Activity, Timing, Interaction Overflow, Information Flow and Profile Diagram.
SYSML SUPPORT	Support modeling with SysML diagrams: Requirement, Block Definition, Internal Block, and Parametric Diagram.
ADDITIONAL DIAGRAMS	Support to create Entity-Relationship Diagrams (ERD), Data-flow Diagrams (DFD) and Flowchart Diagrams.
CUSTOM UML PROFILE	You can define your own UML Profile with stereotypes. Each stereotype can have custom icons.
CROSS-PLATFORM	Work with same UX in multiple platforms including MacOS, Windows and Linux.
AUTO UPDATE	StarUML checks latest updates and install automatically for MacOS and Windows.
RETINA DISPLAY SUPPORT	Supports Retina (High-DPI) Display. All diagrams, texts and icons are razor sharp and can be exported to High-DPI images (PNG and JPEG).
EXTENSION MANAGER	Easily discover and install third-party extensions. Many extensions are open source and hosted on Github. Fork one and make your own.
MODEL-DRIVEN DEVELOPMENT	Modeling data are stored in a very simple JSON format, so it can be used easily to generate custom codes with CLI (Command-Line Interface).
FAST MODELING	Supports many shorthands in Quick Edit to create elements and relationships at once such as sub-classes, supporting interfaces, etc.
DARK AND LIGHT THEMES	Support light and darks themes, so you can choose a theme more comfortable.
COMMAND PALETTE	Command Palette allows to search and execute commands in StarUML as well as installed extensions.
CODE GENERATION	Supports code generation for various programming languages including Java, C#, C++ and Python via open source extensions.
QUICK FIND	Quick Find allows to find models, views and diagrams and select the element quickly.
ASYNCHRONOUS MODEL VALIDATION	Many model validation rules are defined and checked asynchronously whenever you save or open your model files.
PUBLISH HTML DOCS	Easy to share models with other analysts, architects, and developers by just publishing HTML Docs.
PDF EXPORT FOR CLEAN PRINTING	Diagrams can be exported to PDF for clean printing with printing options like page layout and sizes.
MARKDOWN SUPPORT	Use markdown syntax to edit element’s documentation with support of syntax highlighting and preview.
