PerfBee Real User Monitoring
PerfBee Real User Monitoring reports Core Web Vitals from real visitors to help teams understand website performance under real-world conditions. It tracks LCP, CLS, INP, FCP and TTFB, presents P75 metrics, and breaks data down by page, device, browser and connection. The dashboard can surface top pages by impact and comparisons between devices and browsers. Each page load sends those metrics along with device type, browser, connection speed and broken resource URLs.
Additional diagnostics include broken-resource detection, JavaScript error tracking, LCP attribution and lab-versus-real-user comparisons. Alerts compare performance with a seven-day baseline and email the team when LCP, CLS or INP degrades. Setup uses an asynchronous, deferred script tag, without an SDK, npm package or configuration file. The privacy policy says the script does not collect IP addresses, user IDs, cookies, names, emails or other personally identifiable information; URLs are paths only by default. RUM is included in Business at $59 a month and Business+ at $119 a month.
