Visit a few pages. Within seconds you’ll see live performance metrics on your WordPress dashboard. ⚡ Why This Plugin?

But what is slow?” Rayetun Site Monitor answers that automatically. The beacon captures the exact DOM element responsible for Largest Contentful Paint — whether it’s a hero image, a video embed, a heading, or a background. See the element tag, CSS class, and image source right alongside the metric. No guesswork. No DevTools digging.
