Rewind the bug. Watch it happen.
Scrub through the visit that led to a report, with the page, console and network in sync.
A replay shows what your tester did before reporting a problem, next to the console and request evidence that was actually recorded. It is built for debugging one bug, not for analysing every visitor.

What you can inspect
Seek through the timeline and change playback speed. Open the recorded clicks, console and request panels to see the context at that moment.
- Select a recorded click to jump to it.
- Inspect the captured element in the DOM inspector, as it was when it was recorded.
- See console and network entries for the capabilities that were enabled.
- Follow a request into your server with backend evidence, where it is set up.
Recorded where the review happens
Recording starts with a hosted review session, or in the browser extension when Record Session Replays is allowed for the device and project. Make a short test action first and check the replay before reproducing the bug.
A replay shows what was recorded. It does not re-run the original requests.
Export it, open it locally
Download a replay as a file, then open a supported .json or .json.gz recording in Claron's local player. The local player reads it in your browser without creating a new cloud recording.
Privacy first
Recordings can contain application text and data, so review with dedicated test accounts. Project diagnostic permissions control who can open cloud evidence; a downloaded file is a separate copy, so share it only with authorized people.
