PerfDelta is a website speed test built around comparison. The free test measures three pages of a site on mobile and desktop and puts real-user Core Web Vitals from the Chrome UX Report next to Lighthouse lab metrics. Up to two competitor domains show where the site leads or trails, a benchmark places it against every domain tested so far, and the recommendations list estimated savings and the affected files. Paid plans add scheduled monitoring, email alerts, full history, PDF export, MCP and a REST API.
