About PerfDelta
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.
