Instant Replay is an opt-in feature. Once enabled, Jam keeps a rolling 2-minute buffer of DOM activity locally so you can share what just happened without reproducing the bug.

​
Enable Instant Replay

  1. Open the Jam extension.
  2. Go to Settings → Instant Replay.
  3. Toggle Enable Instant Replay.
Your preference follows your Jam account, so Instant Replay stays on across browsers and profiles.

​
Key benefits

  • Complete technical context: Every Instant Replay automatically includes DOM session replay, console logs, network requests, and device information.
  • Zero workflow disruption: You don’t need to set up a recording or reproduce the bug. Just capture and share.
  • Engineer-ready format: All diagnostics are bundled into one link you can drop into a ticket or send directly to an engineer.
  • Privacy controls: Crop the video portion before sharing to remove any content you don’t want included.

How to trigger Instant Replay

1

Encounter the bug

Continue using the page. Jam tracks DOM changes automatically in the background.
2

Trigger Instant Replay

Click the Jam extension icon and select Instant Replay, or use the keyboard shortcut Shift + Cmd + X.
3

Review and crop (optional)

In the draft window, preview the captured session. Crop the video portion to remove any sections you don’t want to share.
4

Create and share

Click Create to upload and generate your shareable link. Jam copies it to your clipboard.

​
What Instant Replay captures

Every Instant Replay includes:
  • Up to 2 minutes of DOM session replay
  • Console logs (errors and warnings)
  • Network requests with full inspection
  • URL, timestamp, and country
  • Device, OS, and browser
  • Viewport size and network speed
Instant Replay is a DOM session replay, not a video recording of your screen. Jam periodically snapshots HTML changes and stitches them together to render a replay inside an iframe. No screen video is ever recorded or stored locally.

​
Capture limits

Capture duration is limited by available local storage. On pages that generate large volumes of DOM changes rapidly, the buffer fills faster and the lookback window shortens.

​
Performance

On heavy websites, Instant Replay can use significant browser memory and affect performance. Jam has safeguards in place so the feature stays lightweight. Jam automatically disables Instant Replay on heavy websites (many animations, frequent data re-renders, like crypto tickers or spreadsheet apps) to protect performance. You can override this in the Jam extension settings if your device handles the load well. To revert, remove the website from the override list in extension settings.

​
Privacy

Instant Replay is built to be privacy-first:
  • All DOM snapshots are stored locally in your browser, never sent anywhere.
  • The local buffer is permanently deleted every 120 seconds.
  • Nothing leaves your computer until you explicitly click Create.
  • Only the content you choose to share is uploaded.

​
Disable Instant Replay

You can turn Instant Replay off anytime from Settings → Instant Replay. You can also keep it on globally but block it for specific websites.
Up to 2 minutes of session activity. This may be shorter on newly opened tabs or websites with heavy data loads, as the local buffer fills more quickly on those pages.
Yes. You can crop the video portion of your Instant Replay before sharing to remove any content you don’t want included.
Every Instant Replay includes DOM session replay, console logs, network requests, URL, timestamp, country, device information, browser details, and viewport size.
No. Instant Replay snapshots HTML changes in the DOM. It does not record a video of your screen. Nothing is uploaded until you explicitly click Create.
