Detailed Review
Software Ideas Modeler is a CASE tool and diagram editor that its site says supports UML, SysML, ERD, BPMN, ArchiMate, flowcharts, user stories and wireframing. Version 15.55 was released on 13 August 2026 according to the home page.
The end-user licence agreement names Dušan Rodina, Šancová 3/A, 811 04 Bratislava, Slovakia as owner of all rights and licensor, and the contact page lists the same address with the note European Union.
Notations covered
The feature page lists UML diagrams, BPMN workflows, SysML models, ArchiMate, wireframes and flowcharts, plus macros for repetitive tasks and tools for code and database integration.
Real-time collaboration, in which people share, edit and comment on models, needs a Software Ideas Server installation.
Editions and licence
The licence describes five editions: Standard, Premium, Professional, Ultimate and Customized, plus Software Ideas Server and its management application. Anyone may try the software for up to 30 days at no charge.
The Standard edition is freeware for non-commercial users only, meaning schools, non-profit organisations and individual home users. Everyone else needs a paid edition after the trial.
Who is behind it
The EULA and the contact page name one person, Dušan Rodina, as licensor and operator, so the vendor is an individual rather than a larger company.
Limitations to Consider
The pages checked show no prices, so the cost of the paid editions has to be requested or read on the vendor's order page. The free Standard edition excludes commercial use. The licensor is a single individual, which matters for support continuity. Collaboration requires you to install Software Ideas Server yourself.
