Session Tracking

What is Session Replay?

Q: What is Session Replay?

A visual playback of a user's session, showing exactly what they saw and did in your application.

Session replay reconstructs a user's session as a video-like playback, showing every page they visited, every click they made, every form they filled out, and every error they encountered. It gives you a first-person view of the user experience.

Modern session replay tools don't record actual video — they capture DOM changes, mouse movements, and user interactions, then reconstruct the experience in a lightweight player. This approach uses far less bandwidth than video recording while providing a pixel-perfect reproduction.

Session replays are invaluable for debugging user-reported issues, understanding why users drop off in funnels, validating UX assumptions, and building empathy with your users. They transform abstract analytics data into concrete, watchable experiences.

Example

A user reports that they 'can't complete checkout.' Instead of guessing, you watch their session replay and see that a third-party payment widget fails to load on their browser version. You add a fallback payment method and notify the affected users.
