UML modeling software helps you represent systems visually and connect models with development work. Compared on UML diagram types, code generation, and reverse engineering, the entries offer useful ways to assess how each fits your modeling needs. You can also weigh model repository and team collaboration features if you work with shared models, along with deployment and supported platforms. Visual Paradigm, Eclipse Papyrus, and BOUML are among the named options to consider. Free-plan availability and paid-from pricing add cost context. As you compare, consider the diagrams you need to create, whether you want to move between code and models, and how your team will access and maintain its work.
22 UML modeling software ranked on what their makers publish — plans and prices, free tiers, platforms and the facts on their own pages.
