About Datadog RUM

Datadog RUM provides comprehensive, end-to-end visibility into web application performance by tracking real-time user interactions and technical metrics. Designed for engineering and product teams, it monitors Core Web Vitals, resource loading, and frontend errors to optimize the digital user journey. Its primary differentiator is the seamless integration of frontend telemetry with backend infrastructure monitoring within the unified Datadog platform. This allows teams to correlate client-side performance issues directly with server-side bottlenecks, enabling faster troubleshooting and improved application reliability for modern, data-driven organizations.
