Product · RUM & Session Replay

See the user journey that happened before the backend failed.

Connect browser sessions, actions, errors, Web Vitals, and frontend requests to the same trace and time context used by backend telemetry. Reproduce the journey in Session Replay, then continue into the responsible backend span.

Frontend evidence, connected to the incident.

Move from an affected user or slow page to the exact replay moment, frontend request, and backend trace without rebuilding context.

01

RUM

Session explorer and event timeline

Browse sessions by user, geography, browser, duration, and error count, then inspect ordered views, actions, requests, and errors.

02

Performance

Web Vitals and frontend API performance

Track LCP, FID, CLS, and TTFB alongside API volume, p50/p95 latency, and error rate for real browser traffic.

03

Errors

Error tracking with source maps

Group JavaScript errors by fingerprint, count impacted users, inspect affected sessions, and map minified frames back to source.

04

Correlation

Session-to-trace correlation

Use W3C trace context carried by RUM actions to open the backend trace, with time correlation as a fallback.

05

Ownership

Replay data on your object storage

Keep replay events and their ordered session metadata on infrastructure you control, alongside the rest of your telemetry.

06

Session Replay

Interactive replay and privacy controls

Reconstruct the page, jump between views, actions, errors, and requests, skip inactivity, adjust playback speed, and apply sampling and masking controls.

workflow

From a browser symptom to the responsible backend span.

The useful unit is not a video alone. It is the replay moment, browser event, error, request, and backend trace kept in one investigation.

  1. 101 · Capture

    Receive sessions, actions, errors, and replay events

    Use the browser SDK to configure collection, sampling, and privacy policy while preserving trace context on frontend requests.

  2. 202 · Prioritize

    Find slow or error-heavy experiences

    Filter real sessions and use Web Vitals, error rate, affected users, and frontend API latency to choose where to investigate.

  3. 303 · Reconstruct

    Replay the journey at the failure

    Reconstruct the page and jump directly to the views, actions, errors, and network requests surrounding the issue.

  4. 404 · Correlate

    Open the backend trace without copying IDs

    Carry the session window and trace context into the request path, service, logs, metrics, and profiles.

proof / shipped

One frontend investigation, end to end.

RUM, Session Replay, error tracking, performance, source maps, and trace correlation share one session and time context.

  • Search real sessions and affected users
  • Replay the exact journey around an error or slow request
  • Resolve minified JavaScript frames with source maps
  • Continue from the browser request into the backend trace
