How does Instant Replay work?

When enabled, Instant Replay keeps track of HTML changes in the website you are on, by periodically snapshotting the DOM. The snapshots are stored locally on your computer until you create a Jam. At that point, Jam stitches together the DOM snapshots to look like a video. If you inspect it, you’ll find HTML replaying inside an iframe. Instant Replay snapshots HTML changes, not video. It works like the browser’s local storage for page snapshots. No screen recording happens, even locally on your computer.

How does Instant Replay preserve my privacy?

Instant Replay is built for privacy first. Everything happens locally on your computer, nothing leaves unless you share it, and the local buffer is permanently deleted every 120 seconds. Snapshots stay in your browser’s local storage until you click Create. Then we upload them so you can share the Jam as a link or ticket.

How to disable Instant Replay

Instant Replay is off by default. If you enabled it, you can turn it off anytime from Settings → Instant Replay in the Jam extension. You can also keep it on globally but block it for specific websites.
