One embodiment involves a system comprising a network, a server, and a requesting device. The server and requesting device are connected with the network. The server comprises a processor configured to receive a request from the requesting device and determine information about the requesting device based at least in part on the request. The processor is further configured to determine an abstract representation of an application and at least one mapping from a plurality of mappings based at least in part on the information about the device. The abstract representation comprises a plurality of components. Each mapping comprises an attribute for at least one of the plurality of components. The processor is further configured to generate a version of the application on-the-fly based at least in part on the abstract representation and the at least one mapping and send the version of the application to the requesting device.
