Versions:
UML .FRI 2.2.2, published by Ján Janech, is a lightweight desktop application positioned within the UML and domain-specific modeling category, offering a single-version, no-cost solution for creating, editing, and visualizing software blueprints. Engineered as a flexible DSM (domain-specific modeling) tool, the program lets analysts, architects, and students draw class, use-case, activity, sequence, state-machine, component, and deployment diagrams while simultaneously supporting custom profiles and stereotypes that adapt the notation to company-specific terminology. Typical use cases include forward engineering of object-oriented systems, reverse engineering of legacy code bases into navigable models, collaborative requirement capture during early project phases, and educational illustration of design patterns in academic courses. The workspace relies on an intuitive drag-and-drop palette, snap-to-grid layout, and live syntax checking that immediately flags violations of UML 2.x well-formedness rules; models are stored in human-readable XML so they can be version-controlled with any SCM system. Export filters generate PNG, SVG, PDF, and XMI output for insertion into specifications, wikis, or third-party code generators, while scripting hooks allow batch transformation of model elements into skeletal Java, C#, or Python source. Because the tool is delivered as a portable executable requiring no administrator rights, it can be carried on a USB stick and launched on any Windows machine without installation footprint, making it convenient for field consultants and lab computers alike. UML .FRI is available for free on get.nero.com, with downloads provided via trusted Windows package sources such as winget, always delivering the latest version, and supporting batch installation of multiple applications.
