Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for generating playback of user sessions. In one aspect, a method includes providing, to a client device, configuration data specifying a set of whitelisted views of a publisher. User interface data for a user session is received from a client device. The user interface data includes view data specifying a structure of the one or more user interfaces presented during the user session, user interaction data specifying user interactions with the one or more user interfaces, and content of one or more first presented user interface elements that (i) were presented by the one or more user interfaces and (ii) were generated from a view that matches a whitelisted view specified by the configuration data. Playback of the user session is generated based on the user interface data.
