Catchpoint Expands WebPageTest

Catchpoint announced the expansion of the WebPageTest platform, an open-source web performance testing suite.

It allows web developers, SEO managers and performance teams to run instant tests from various locations and receive a detailed performance audit of their web pages and web applications.

WebPageTest’s new Opportunities and Experiments features help these teams code with confidence, instantly providing actionable insights and automated experiments for implementing best practices and building quick, usable and resilient websites. WebPageTest Opportunities and Experiments allows performance teams to code with confidence by automatically generating and testing performance tweaks to eliminate blocking scripts, optimize image rendering, and minimize layout shifts with zero code changes.

WebPageTest Opportunities allows users access to unique and actionable insights generated by test results. IT teams receive suggested best practices, such as deferred or async JavaScript, right-sized images, and security fundamentals. Built by leading performance experts with decades of experience, WebPageTest Opportunities guides teams to implement best practices and create lightning-fast websites that delight and convert more users.

WebPageTest Experiments gives users access to custom and automatically generated optimization tests that show how their websites could benefit from specific, actionable improvements with zero changes to the codebase. By making on-the-fly changes to the site’s HTML, JS, and CSS without actually changing any deployed code and comparing it to a control test, developers can instantly gauge the potential for success of their performance tuning. This will prove to be an essential piece of any developers’ or site owners’ toolbox, improving the pace of development and increasing their ability to code with confidence.

“For devs and businesses alike, WebPageTest is continuing to evolve as the gold-standard of performance testing,” says Mehdi Daoudi, CEO at Catchpoint. “Teams will save countless hours of triage by accelerating performance prototyping for both production and in-prod sites. The ability to test and tweak major performance improvements without changing any production code will help to remove red tape and improve the org-wide adoption of performance as a culture.”

In addition to Opportunities and Experiments, WebPageTest is also substantially enhancing the platform experience with access to Private Tests, Bulk Tests, and Priority Testing. As of today, all existing API users of WebPageTest will be also be able to access all new features.

WebPageTest will be hosting a series of livestreams, events, and competitions over the coming month to help users experience, explore, and test out these incredible new features. For more information, please visit our events page.
