variability.dev: Towards an Online Toolbox for Feature Modeling

The emergence of feature models as the default to model the variability in configurable systems fosters a rich diversity in applications, application domains, and perspectives. Independent of their domain, modelers require to open, view, edit, transform, save, and configure models as well as to collaborate with others. However, at the time of writing, the top five results when googling ``Online Editor Feature Model’’ point to editors that either have minimal functionality, are unmaintained or defunct, or require an offline installation, such as FeatureIDE. In this work we present a preview of our in-development online toolbox for feature modeling, variability.dev. In particular, we showcase our collaborative feature-model editor and our online configurator both of which are built on top of the FeatureIDE library.
