Implementing OpenTelemetry for Frontend Monitoring

Frontend performance today goes far beyond page load time. In modern Next.js applications, user experience depends on multiple asynchronous API calls, dynamic rendering, and real-time interactions. This makes traditional error logging and synthetic checks insufficient. This is where OpenTelemetry becomes essential. OpenTelemetry enables end-to-end tracing from the browser to backend services, giving teams clear visibility into latency, failures, and performance bottlenecks from the user’s perspective. Modern web applications require sophisticated OpenTelemetry monitoring to understand user experiences across complex frontend architectures. This guide walks through a production-ready OpenTelemetry frontend implementation for Next.js applications, breaking down each component with detailed explanations. Read full blog... Exei
