FullStory

FullStory is a digital experience analytics tool that replays user sessions in the browser and tags friction signals such as rage clicks and dead clicks.

Replay in this category is not video: DOM mutations and input events are recorded and later rebuilt in a browser, which keeps the payload small and makes sessions searchable by event. A second layer, autocapture, records interactions without prior definition and allows retroactive questions. Two limits matter: recording is usually sampled, so counting inside recorded sessions does not represent all traffic, and because page content is captured, masking sensitive fields is a compliance requirement rather than an option.
