Documentation Grafana Cloud Monitor applications Frontend Observability Introduction

Introduction to Frontend Observability

Frontend Observability gives you insight into how users experience your application in production. It collects real-user performance data, JavaScript errors, browser logs, and client-side traces directly from the browser, then sends this telemetry to Grafana Cloud for analysis and visualization. With this data, you can understand how your application loads, renders, and behaves across different devices, browsers, and network conditions.

Unlike synthetic tests or local benchmarks, Frontend Observability measures performance as real users experience it. These insights help you detect issues related to deployments, regions, user cohorts, and frontend code paths that are otherwise difficult to surface.
