Rage click
A rage click is a burst of repeated rapid clicks on the same element or spot, and it is the most widely used behavioral signal of user frustration. It usually means the user expected something to respond and it did not: a dead button, a slow handler, or an element that only looks clickable.
How it works
Detection runs on click events, not pixels: a common rule flags 3 or more clicks on the same target within roughly 1 to 2 seconds, with thresholds tuned per product to keep false positives (double-click habits, games, rapid form navigation) tolerable. In an rrweb event stream, rage clicks fall out of source: 2 mouse interaction events sharing a target id in a tight timestamp window; the events documentation defines the source values. This means they can be detected in stored recordings retroactively, without any extra instrumentation at record time.
Where you encounter it
As a session filter ("show me sessions with rage clicks") in every replay tool, as an alerting trigger, and as the canonical example of AI-assisted frustration detection; see frustration signal.
