Techniques for managing generation and rendering of user interfaces on client devices

Techniques and systems are provided for processing user interface content. For example, a server computer can receive a user interface event corresponding to a user interface of a device (e.g., a client device, another server computer, or other device). An application associated with the user interface event can be determined, and an interface model 5 can be generated using the application associated with the user interface event. The interface model defines state information for one or more graphic objects of the user interface. The state information results from the user interface event. The server computer can send the interface model to the device, which enables the device to render the user interface.
