In their own words
Eclipse Papyrus
Eclipse Papyrus is a free modeling environment for UML and related extensions, with desktop and web options. It lists implemented standards including UML 2.5, SysML 1.6, fUML 1.3, ALF 1.0.1, MARTE 1.1, PSCS 1.1, PSSM 1.0, and ISO/IEC 42010. Teams can tailor profiles, model explorers, diagram notation and style, properties views, palettes, and creation menus. With Moka, models can run through animation and simulation. Papyrus-Web supports simultaneous work on a shared model in a browser, with changes visible to stakeholders; its editors cover diagrams such as class, component, use case, activity, state machine, and communication. Desktop downloads are listed for 64-bit Windows and Linux, as well as Intel and Apple Silicon macOS. Papyrus requires a Java 21-compatible JVM and is released under the Eclipse Public License v2.0. Related tools provide code generation and reverse engineering in C++, C, Java, and Python, plus documentation generation for LibreOffice, Word, and PDF. Papyrus-Web can be tested locally with Rancher Desktop or Docker Desktop, with deployment documentation linked.
