What Eclipse Papyrus is

Eclipse Papyrus is a free modeling environment dedicated to UML and its extensions. It lists implemented standards including UML 2.5, SysML 1.6, fUML 1.3, and ISO/IEC 42010, alongside several other modeling standards. Users can customize profiles, explorers, diagram styles, properties views, palettes, and creation menus. With Moka, models can be run through an animation and simulation framework. Papyrus-Web runs in a browser on a server and supports simultaneous work on one model, with changes visible to stakeholders. Its web editors cover class, component, activity, state machine, and other diagram types. Desktop downloads are listed for Windows, Linux, and macOS; the download page requires a Java 21-compatible JVM. Related tools include Papyrus Designer for code generation and reverse engineering in C++, C, Java, and Python, and Papyrus-Model2Doc for documentation output to LibreOffice, Word, and PDF. The project provides community resources including a wiki, discussions, mailing lists, issue trackers, Git repositories, and Jenkins.
