Session replay
Session replay is a reconstruction of a user's visit to a website or app, built from events the page emitted — such as clicks, scrolls, and DOM changes — rather than from a camera or a screen-recording file. In Replayly, a lightweight tracker sends those events to ingest, and a player in the dashboard plays them back with speed controls, skip inactivity, and a metadata panel.
Why it matters
Teams use session replay to understand friction that metrics only count. A drop-off in a funnel does not show whether the button was hidden, the validation was confusing, or a script error interrupted the click.
Because the recording is an event stream, privacy rules can be applied in the browser before data is stored. Replayly masks input values by default and can respect Do Not Track or wait for consent.
Session replay is not a substitute for analytics, interviews, or error monitoring. It is a way to watch a single visit in context. Read the session replay feature page for how Replayly implements it, including filters and hosting options.
