Our verdict on WebPageTest
WebPageTest is a website performance testing tool for developers and teams investigating how web pages load. It runs tests using real browsers and locations, then provides results for analysis at both the page and request level. Its focus is performance measurement rather than a broad website optimization workflow, making it a fit for teams diagnosing load behavior across different test conditions. The product is available through the web and an API, and deployment options include cloud and self-hosted. It began as an open-source project and is now owned by Catchpoint.
Testing options extend beyond standard page runs: WebPageTest supports Lighthouse tests and scripted tests, while its API allows teams to work with the tool programmatically. Private test instances are also among its capabilities, which can suit teams that want a private testing environment. These features make the product relevant when a team needs to investigate page loading and request behavior in defined test runs. It is centered on gathering and examining performance results, not on applying broader optimization methods within the product.
WebPageTest has a free plan as well as a paid Pro subscription with additional capabilities. The available plan information does not establish specific prices or which capabilities are reserved for Pro, so buyers should check the current vendor pricing before choosing a plan. Its narrow scope is an important trade-off: it does not provide site audits, A/B testing, or page-speed monitoring. Choose it when browser- and location-based performance testing, scripting, Lighthouse testing, or API access match the need. Teams seeking audits, experiment management, or ongoing speed monitoring should consider a product that covers those tasks.
