Methods, storage systems and computer program products implement embodiments of the present invention that include running by a web browser, a web-based application including a set of web pages, and identifying changes in the web pages rendered by the web browser while running the web-based application. For each identified change, a corresponding state of the web-based application is recorded, wherein the corresponding state includes browser-executable code for a given web page being rendered, and one or more transitions from the corresponding state to one or more other states is also recorded. The recorded states and the recorded transitions are compiled into a state machine model of the web-based application, and a demonstration of the application is generated using the state machine model.
