RUMvision [Real User Monitoring]

RUMvision is a real user monitoring tool that tracks your website's performance by collecting data directly from your visitors' browsers. It measures Core Web Vitals like CLS (Cumulative Layout Shift) and INP (Interaction to Next Paint), providing immediate feedback on how actual users experience your site. Unlike simulated tests, it captures every page load, scroll, and interaction as it happens, giving you a true picture of site performance.

The tool works by adding a small JavaScript snippet to your website, which begins sending real-time data within five minutes. It automatically checks every new release for performance regressions, opening issues when problems are detected and closing them when they're resolved. A standout feature is its third-party script monitoring, which rates external services like analytics or ads as Good, Moderate, or Poor based on their actual impact on your site's speed.

RUMvision is particularly valuable for development teams who need immediate feedback on deployments and marketing professionals focused on SEO and conversion rates. It helps identify performance bottlenecks that affect real users, allowing teams to fix issues before they impact revenue or search rankings. The service is GDPR compliant and hosts all data within the EU.
