New Relic

New Relic is an observability platform that provides performance monitoring, error tracking, and troubleshooting for applications across the full stack. It offers application performance monitoring, infrastructure monitoring, browser and mobile monitoring, synthetic checks, log management, and distributed tracing that follows requests across microservices and third-party APIs.

The platform collects telemetry data from instrumented applications and infrastructure, presenting it through dashboards, alerts, and query interfaces. New Relic Query Language allows teams to ask specific questions about their data, such as identifying the slowest database queries in the last hour or correlating error spikes with deployment events. Custom dashboards combine metrics from different sources into unified views.

For web development teams, New Relic helps answer critical questions about production behavior. Why did page load time increase after the last deployment? Which API endpoint is causing the most errors? How does server response time vary across geographic regions? Having this visibility transforms debugging from guesswork into data-driven investigation, reduces mean time to resolution for incidents, and provides evidence for prioritizing performance optimization work.
