About
A lightweight Chrome extension that displays Core Web Vitals (LCP, FCP, CLS, TTFB) directly on any website. Capture a “performance snapshot” at one point in time and easily compare it against a later visit. For example, record metrics on YouTube at 10:30 AM, revisit at 3:00 PM, and instantly see how site performance has changed. Perfect for developers, testers, and performance engineers who need a simple overlay to track, measure, and compare website speed and user experience over time.
