Watch real user sessions to debug issues and improve UX

Session Replay records user sessions so you can watch exactly what users do in your app. See where they click, how they navigate, and where they encounter problems. Unlike traditional session recording, Session Replay respects privacy by automatically masking sensitive data.

Debug issues faster by watching sessions that triggered errors. Understand UX problems by seeing how users interact with your interface. No more guessing what went wrong or how users experienced bugs.

Privacy by Default

Session Replay automatically masks passwords, credit card numbers, and personally identifiable information. Configure custom masking rules for industry-specific data. Users never see sensitive information in recordings.

Recording Features

Capture DOM changes, network requests, console logs, and custom events. Filter sessions by error occurrence, user properties, or specific actions. Share session links with your team for collaborative debugging.

import SessionReplay from '@sessionreplay/sdk';

SessionReplay.init({
  projectKey: process.env.SESSION_REPLAY_KEY,
  maskAllText: false,
  maskAllInputs: true,
  ignoreClasses: ['sensitive-data']
});

// Add custom context
SessionReplay.setUser({
  id: user.id,
  plan: user.plan
});

// Track custom events in replay
SessionReplay.track('checkout_started', {
  cartValue: 199
});

Analysis Tools

Filter sessions by duration, rage clicks, error occurrence, or conversion status. Create playlists of interesting sessions to share with stakeholders. Export sessions as videos for presentations.

Performance Impact

Session Replay adds less than 10KB to your bundle and uses minimal CPU. Recordings are compressed and uploaded asynchronously without blocking user interactions. Configure sampling rates to balance coverage with performance.

Integrate with error tracking tools to automatically attach session replays to bug reports. Your support team can watch what users did before reporting issues.
