Session Replay records changes to the page's document structure and user interactions, then reconstructs them in a player. It does not store a video stream.
Playback stays synchronized with navigation, clicks, input activity, network requests, and console events when console capture is enabled. The recording links to every browser span from the same session in Live view.
The recorder masks rendered text and input values by default, leaves console capture off, and removes query strings and fragments from captured URLs. Review the privacy controls before recording sensitive pages because document attributes, CSS-generated content, resource URLs, and custom events need separate handling.
Where to find it: enable Frontend observability in Settings → Early Access, then open Frontend → Session Replays. See the Session Replay guide.
