Systems and techniques are described for executing an application locally. A described technique includes providing, by a user device and to a remote application system, data identifying user events associated with the application while data communication is available between a user device and a remote application system executing an application. The user device receives from the remote application system user interfaces for the application and presents the user interfaces on a display of the user device. The user events are provided as inputs to a local version of the application executing on the user device. A determination is made that data communication between the user device and the remote application system has become unavailable. In response, a user interface generated by the local version of the application is presented on the display of the user device.
