## What real users experience

[Frontend Observability](/docs/grafana-cloud/monitor-applications/frontend-observability/) captures performance data from actual browser sessions. You instrument your frontend once, using an open source SDK that emits standard OTel signals.

- **See what your users actually experience**: real browser sessions, Core Web Vitals, and performance data from actual user traffic, not synthetic proxies.
- **Find and fix frontend errors fast**: triage errors with automatic grouping, detailed stack traces, and actionable guidance.
- **Trace problems from browser to backend**: connect a user’s frontend session to the exact backend service call that caused the issue, with full distributed tracing context.
- **Analyze frontend data in the workflow you already use**: query and visualize frontend performance alongside your application insights, logs, and traces in Grafana dashboards.

## What keeps you up at night

Role / WorriesWhat you get with the app

**Developer**

- Users report checkout is slow or a page hangs, but backend metrics look fine and it doesn’t happen in staging
- Can’t reproduce it, can’t explain it

<!--THE END-->

- Real user sessions broken down by page, browser, device, and geography, so you can isolate where it’s happening and who is affected
- Tie performance data to deployment markers to catch regressions before users find them

**SRE, On-Call Engineer**

- During an incident, the frontend team blames the backend and the backend team’s dashboards look clean
- Hours spent debating ownership instead of fixing the problem

<!--THE END-->

- Distributed tracing connects the browser session to the exact backend span. Both teams see the same evidence.
- No more finger-pointing across separate dashboards and different data

**Frontend, Web Engineer**

- Error reports arrive as support tickets and screenshots
- No fast path from “a user saw this” to “here’s what broke and why”

<!--THE END-->

- Errors are automatically grouped and prioritized by user impact
- Detailed stack traces give you a direct path from symptom to root cause

**Engineering Manager, VP Engineering**

- Paying for a standalone RUM tool, a separate APM, and a separate logging platform
- Engineers still have to manually stitch them together during incidents

<!--THE END-->

- Browser telemetry in the same Grafana Cloud instance you already use. One fewer vendor, one fewer login.
- Frontend performance alongside your logs, traces, and application data. No manual correlation.
