Why Use Page Load Timer?

For Everyone

Ever wonder if a website is slow or just poorly optimized? Get an instant answer. See exactly how long a page takes to load and which part is slowing it down. Explore a clear breakdown of the loading process. No technical knowledge or complex tools required.

For Developers

Analyze Core Web Vitals in real time while the page loads. Break down the loading process step by step and pinpoint the exact API call, script, or resource impacting your render path. No need to open Chrome DevTools or rely on heavy, specialized tools.

Customize Your View

Tailor the settings to your needs:

  • Badge: Show / hide load time on the icon.
  • Themes: Auto, Light, or Dark mode.
  • Density: Compact or Roomy layouts.

Privacy First

Your data stays on your device.

This extension does NOT collect any data. It uses the browser's local Performance API to calculate metrics right on your device. No analytics. No tracking servers.
