RUMvision is a Real User Monitoring platform focused on Core Web Vitals and website performance. Instead of relying on synthetic tests or Lighthouse scores, RUMvision uses real visitor data to show how a website performs across different pages, devices, browsers, templates, and user conditions. RUMvision helps developers, SEO specialists, agencies, and performance teams understand where performance issues occur, what is causing them, and where optimization efforts will have the most impact. The platform monitors metrics such as LCP, INP, CLS, TTFB, and other performance signals using the web-vitals library. Built-in health checks turn this data into clear, actionable recommendations, making technical performance data accessible to both experienced developers and less technical users. With RUMvision, teams can continuously monitor Core Web Vitals, detect regressions, investigate performance bottlenecks, and prioritize improvements based on real user experiences.
