The No. 1 model versioning tool for distributed teams


Thanks to LemonTree, we can now also use the proven processes and workflows from classic software engineering for models. The tool also meets all our requirements in change and configuration management. Therefore, we are now very happy to use the tool and also want to evaluate it further with regard to new topics such as BitBucket or package management.

The control of all versions and variants of the models created in the development process was the most important requirement for the stable anchoring of MBSE in the company. LieberLieber supported us very well in this with their profound practical knowledge as well as with tools such as Enterprise Architect and LemonTree, thus promoting internal persuasion.

In general, standards such as IEC 61508 require the existence of configuration management. This applies to all elements, including the UML models. LemonTree from LieberLieber is the key for us to be able to determine what has been changed in which revision.

Workstations with LemonTree






Extensions & Adaptations

So that you can incorporate LemonTree into your day-to-day work in the best possible way, we’ll configure the tool according to your requirements and, if necessary, even extend its range of functionalities. Regardless of which language you do your modeling in (UML, SysML, BPMN, etc.) or if you would like you have additional features in the GUI, we are able to create the right solution for you. By the way, LemonTree can diff & merge models from Enterprise Architect as well as from other modeling tools.


Support & Maintenance

Our Support Team is ready to help your work with LemonTree progress as comfortably as possible. We also have training specialists with years of project knowledge standing by to ensure you receive the greatest benefit possible when using your system, and we’ll incorporate your experience gained from using LemonTree to continually improve its functionality and effectiveness. Don’t hesitate to contact us – we’ll find the right solution for you!



LemonTree can be seamlessly integrated with existing versioning systems (Subervsion, Git or PTC), allowing the centralized, automated management of model versions. This also enables parallel editing of models within a team environment, the standard approach with source code for years. In such case, LemonTree is addressed as a 3rd-party Diff & Merge tool as soon as a model is checked into the central repository.
