Site24x7 Core Web Vitals Monitoring review
Focused RUM for LCP, INP and CLS, with useful segmentation and resource waterfalls.
Reviewed by iTechGuides Editors · Editorial team · Updated Nov 2026
Site24x7 Core Web Vitals Monitoring collects LCP, INP and CLS from real user page loads on websites and web applications. It is aimed at teams that want to understand how real visitors experience page performance, with results segmented by geography, browser, device type and ISP. Percentile distributions and averages give teams different ways to read the measurements, while automatic SPA route tracking supports React, Angular, Vue and Next.js. It is a focused RUM option for teams seeking practical visibility without treating synthetic checks as a substitute for field data.
The feature set goes beyond headline scores: resource waterfalls help identify slow scripts, fonts and images, while threshold-based alerts and long-term trend reports support ongoing monitoring. RUM sessions can also be correlated with session replays and related APM traces when available. Setup uses a JavaScript snippet, so teams should account for adding that instrumentation. Aggregated Core Web Vitals metrics have 15 months of retention; raw session-level retention depends on account configuration.
According to the vendor's pricing page, the broader Site24x7 website monitoring plans are billed annually: Web Uptime is $9 per month and includes 25 websites, a 1-minute polling interval, RUM page views and email support; Web Perf is $36 per month and includes 40 websites, 8 transaction monitors, 8 monitoring locations and 100K page views; Enterprise Plus Web is $899 per month with 2,500 websites, 100 transaction monitors, 16 monitoring locations and 5M page views. A free plan and 30-day trial are available. These are not separate Core Web Vitals-only prices. Choose it for segmented real-user metrics and diagnostics; teams that specifically need synthetic Core Web Vitals testing should look elsewhere.
