A system receives, from a first augmented reality device, a first image of a web application that shows a first element of the web application. The system receives eye tracking information that indicates eye movements of a user looking at different elements of web application. The system determines that the user is looking at the first element and that the first element is actuated. The system receives a second image of the web application that shows an error message. The system determines that the first element is faulty, records user events that led to the error message, and updates an augmented reality message for the first element by indicating that the first element is faulty.
