Hotjar

Hotjar records heatmaps and session replays, showing where visitors click, how far they scroll and where they abandon a page.

Its value is diagnostic rather than statistical: analytics tell you that a page converts badly, and session recordings show you the moment a user hovers over a broken element and leaves.

Recordings raise privacy considerations — masking form inputs and complying with consent requirements is part of setting it up correctly rather than an optional step.
