ADOxx is an environment that allows the creation of a toolkit for a specific modeling technique while using limited resources for development. The result is a toolkit for professional modelers that can be run on Windows, Linux, or MAC. However, such a toolkit is not very friendly for non-IT related stakeholders, as it is primarily aimed at developing the models; it also requires non-trivial installation. This paper is devoted to the project of designing a WEB-based viewer that allows a stakeholder to view a package of models created in an ADOxx-based toolkit. The viewer discussed in this paper was developed for a specific modeling technique called Fractal Enterprise Model (FEM). However, the discussion is of interest not only for modelers using FEM but also for the developers of other ADOxx-based tools. The paper discusses the structure and functionality of the FEM viewer, which can be reused for other toolkits. The authors aim to demonstrate the FEM viewer during the conference.
