Session Replay

Record and replay real user sessions to understand behavior.

Overview

Revlytics includes built-in session replay powered by rrweb. It captures DOM changes, mouse movements, clicks, and scrolls — then lets you play them back in the dashboard.

Session replay is enabled by default. To disable it, add the data-no-replay attribute.

Disable replay

<script
  defer
  data-site="YOUR_SITE_ID"
  data-no-replay
  src="https://revlytics.co/script.js"
></script>

Sample rate

Record replay for only a percentage of sessions:

<script
  defer
  data-site="YOUR_SITE_ID"
  data-replay-sample-rate="25"
  src="https://revlytics.co/script.js"
></script>

This records replay for 25% of sessions. The sampling decision is made once per session and persisted in sessionStorage for consistency.

Value	Behavior
100 (default)	Record all sessions
50	Record 50% of sessions
0	Disable replay (same as data-no-replay)

Privacy

Session replay respects user privacy:

• Input masking — rrweb automatically masks input values by default
• Opt-out — Users who call revlytics.optOut() won’t be recorded
• No replay on sensitive pages — Use URL skip patterns to exclude specific pages

Viewing replays

1. Go to Dashboard → Sessions
2. Click on any session to open the replay player
3. Use the timeline to scrub through the recording

Storage

Replay events are sent to the /api/replay endpoint and stored separately from analytics events. Each replay session includes the full DOM snapshot and incremental changes.
