Sparx Enterprise Architect
Sparx Enterprise Architect is a visual modeling tool for business and IT systems, software and systems engineering, and real-time and embedded development. It supports UML, SysML, BPMN, and other open standards, linking specifications with analysis, design, implementation, testing, and maintenance models. Diagram coverage includes UML use case, activity, state, sequence, communication, package, class, object, component, and deployment types, plus BPMN and SysML. Requirements management supports hierarchical requirements, links to model elements, reporting, and impact analysis. Teams can simulate behavioral models using triggers, guards, and effects, including JavaScript, and generate or reverse engineer code for languages including C++, C#, Java, PHP, and Python. Built-in version control and deployable cloud-based servers support shared projects. The trial lasts 30 days and permits use of any edition, though printed documents carry a watermark. The product supports Windows, Linux, macOS, self-hosting, and API access.
