A processor is operative to store specifications of computer applications in a platform-independent language. A remote client device requests delivery of a specified application for execution thereon. The processor interrogates the remote client device to construct a device configuration, comprising characteristics and capabilities of the remote client device. The processor also obtains a user configuration, and establishes a compilation configuration according to the device configuration and the user configuration. A compiled application in binary format is produced using the compilation configuration and the platform-independent language of the specified application. The compiled application includes customized content and is adapted to run on the remote client device. The processor causes the compiled application to be downloaded to the remote client device.
