Disclosed herein are system, method, and computer program product embodiments for a network-based media device upgrading system. An embodiment operates by receiving a fetch command from a first instance of an application executing locally on a host device. The fetch command is provided to a media device executing a second instance of the application. At the host device, metadata corresponding to the file that was retrieved by the media device is received. A rendering command is determined from the first instance of the application corresponding to displaying the interface including the fetched file as indicated by the metadata. The rendering command is provided to the media device that is configured to display the interface of the application responsive to executing the rendering command.
