Frontend Observability: What and Why
Understand why frontend traces complement server-side monitoring and what signals matter for React apps.
Backend Observability Is Mature
Backend observability is well-established: logs capture events, metrics track resource usage, and distributed traces follow requests through microservices. Tools like Datadog, Prometheus, and Jaeger are widely deployed in production backend systems.
Frontend Observability Is Emerging
Frontend observability is a newer discipline, tracking the user's experience as they interact with your React application. This includes recording user interactions, measuring rendering performance, observing network requests, and capturing JavaScript errors in the browser.
