Systems, methods, and media for a client device discovering remote user interface applications over a network are disclosed. Embodiments may include a remote user interface client of the client device receiving from a content directory service server a code fragment comprising a uniform resource indicator and determining whether the uniform resource indicator is associated with a remote-capable application. Further embodiments may include, in response to determining that the uniform resource indicator is associated with a remote-capable application, engaging by the client device a remote user interface server and receiving by the client device from the remote user interface server one or more display control commands associated with the remote-capable application and displaying a user interface based on the received display control commands. In some embodiments, engaging the remote user interface server comprises switching from the content directory service server. Other embodiments are disclosed and claimed.
