Web Page Test: Website Performance Testing Tool

Web Page Test is an open-source website performance testing tool. It allows users to test the speed of a website from various locations around the world and provides metrics like page load time, TTFB, requests, and more.

What is Web Page Test?

Web Page Test is an open-source website performance testing tool developed by Google. It allows users to test the speed of a website from various locations around the world using real browsers and at real consumer connection speeds.

When you enter a URL on WebPageTest.org, it runs a test from one of over 300 test locations worldwide. As the page loads, it captures metrics like page load time, Time To First Byte (TTFB), total requests, bytes in/out, and more. It generates waterfall charts and request maps to help analyze performance.

After the test completes, you get a breakdown of how your site performed on mobile vs. desktop, on 3G vs cable connections, etc. It highlights optimization opportunities and grades your site based on performance best practices. You can even test authenticated pages by entering HTTP headers.

WebPageTest.org offers an API and open-source code so you can run your own private instances. It's a free tool used by web developers and businesses to monitor site speed and improve web performance.
