The gold standard in web performance testing now with the full power of Internet Performance Monitoring platform—uniting front-end metrics with global synthetics, RUM, session replay, DNS, SSL/TLS, CDN, ISPs, cloud, and much more.

Catchpoint, the leader in Internet Performance Monitoring (IPM), today announced a major evolution of WebPageTest, now fully enterprise-grade and integrated into the Catchpoint Platform.

With this upgrade, Catchpoint expands WebPageTest’s capabilities far beyond page load metrics. The tool now delivers a comprehensive view across the Internet Stack, including global synthetics, Real User Monitoring (RUM), user journeys, DNS, CDN, and more.

For years, the web performance community has trusted WebPageTest for its deep diagnostics, unmatched visibility, and actionable optimization guidance. This includes filmstrips, opportunities, and no-code experiments that teams rely on daily. With this launch, WebPageTest builds on that proven legacy, adding scheduled tests, AI-powered dashboards, alerting, and multi-user access for team collaboration as standard — delivering enterprise-grade power, global Internet visibility, and intelligence.

Why WebPageTest matters more than ever

In today’s market, digital experience is more than a brand pillar; it is the brand. Nearly half of users expect a website to load in two seconds or less, and 53% of mobile users leave a website if it takes over three seconds to load. Google’s Core Web Vitals are now even more critical for SEO and AI search optimization, with speed, interactivity, and visual stability directly impacting revenue and customer trust. Yet, many monitoring tools still provide only partial insights, leaving blind spots in DNS, CDN, and user journeys.

WebPageTest now closes this gap by offering the only complete view of digital experience in the industry, moving beyond front-end code to include every aspect of Internet performance that impacts users. With unified, end-to-end insights, only WebPageTest empowers teams to move faster, dig deeper, and ensure the best digital experience across the Internet Stack.

For organizations looking to expand toward enterprise-grade visibility and deeper insights, new capabilities are now available within the Catchpoint platform, enabling advanced monitoring, analytics, and automation across the full Internet Stack.

Whether protecting revenue, safeguarding SEO, or earning customer trust, WebPageTest now delivers the accuracy, performance guidance, scale, and global visibility enterprises need to thrive.”

“WebPageTest has long been the most advanced tool in any performance engineer’s toolbox,” says Rich Howard, CEO at Optimal. “This closer integration with the broader Catchpoint suite gives us new and exciting capabilities to identify where and why users experience friction in their journey.”

“By uniting synthetics, RUM, DNS, and CDN visibility, we’re giving teams the power to detect, diagnose, and resolve issues across the full Internet Stack, before users ever notice,” said Dritan Suljoti, CTO of Catchpoint. “And now, by bringing front-end teams and SREs together on a common platform with shared data, dashboards, and workflows, WebPageTest empowers everyone to speak the same language of digital experience and work collaboratively to optimize every user’s journey.”
