What is PageGym?

PageGym is a free lab-grade page load behavior analysis tool that helps you find bottlenecks in the way your pages get loaded and rendered.

It features advanced filmstrip and waterfall displays, allows you to compare different test results, and supports a wide range of optimizations that you can try directly from the interface, without making any edits to your code.

Ideal for detecting render blocking resources, layout shifts, total blocking time, measuring TTFB and more.

In contrast to the majority of similar tools, it is an independent development that is not based on Lighthouse.
