About
PerfDelta is a web-based website speed testing and monitoring service for SEO specialists, agencies, and in-house web teams. Its free test scans up to three pages on mobile and desktop, combining real-user Core Web Vitals from the Chrome UX Report with Lighthouse lab measurements. Reports compare a site with up to two competitor domains and a benchmark of previously tested sites, show page-weight breakdowns and request timelines, identify site technologies, and estimate savings in prioritized recommendations naming affected files. Paid plans add scheduled monitoring, performance budgets, email alerts, report history, and PDF exports; Agency and Scale plans also provide CSV export, public dashboards, and a REST API. MCP access lets compatible AI agents request tests and retrieve results. Reports can be shared with clients for performance audits and ongoing site work.

About
Test your user’s real experience with global locations, modern devices, and the latest browser versions. Correlate your user’s visual experience to the technical measurements of your site. Dive into the anatomy of your webpage with components like DNS, TCP, TLS, and more. The WebPageTest code is free to use under the Polyform Shield license, a source-available license. As long as you are not creating a product or service that competes with Catchpoint’s offerings then you are free to do whatever you like with the WebPageTest code, including using it for your own internal use or creating non-competing commercial products from it. In fact, we encourage using the WebPageTest code to build your own value-added applications.
