In this paper, we dealt with the rapid development of client web applications (frontend) in a context where development frameworks are legion. In effect with the digital transformation due to the COVID-19 pandemic we are witnessing an ever-increasing demand of the application development in a relatively short time. To this is added the lack of skilled developers on constantly evolving technologies. We therefore offer a low-code platform for the automatic generation of client web applications, regardless of the platform or framework chosen. First, we defined an interface design methodology based on a portal. We then implemented our model driven architecture which consisted of defining a modeling and templating language, centered on user data, flexible enough to not only be used in various fields but also be easily used by a citizen developer.
