Abstract: Computer-readable media, methods, and systems for generating user interfaces across multiple form factor devices are provided. A server is configured to group a plurality of templates into one or more sets having a different layout for categories of devices or applications. The server receives a request from a device for user interface content. In response, the server parses the request to determine a type for the device or a type for an application requesting the user interface content. The devices or applications are classified by the server based on the identified type for the device or application. A set of appropriate user interfaces is selected based on the type of the device or application. The server maps values to one or more attributes associated with the selected set and transmits the user interface content to the device for rendering.
