Feature modeling is the «de facto» standard to describe the common and variant parts of software product lines. Different tools, approaches and operations for the automated analysis of feature models have been proposed in the last 20 years. However, the installation and usage of those tools use to be time consuming. In this paper we present the WindRose IDE, a cloud based IDE that allows the storage, edition and analysis of feature models while being executed in the cloud. WindRose integrates different feature model analysis operations such as Valid or Number of Products. This reasoning capabilities rely in different well stablished tools like FaMa or FaMiliar.
