Problem
Website performance issues such as slow load times, high TTFB, render-blocking resources, and layout shifts are difficult to diagnose and fix without specialized tools. Developers often lack a clear way to measure the impact of their changes or test optimizations safely before deploying them to production.
Solution
PageGym provides a comprehensive website speed testing platform that analyzes load performance and identifies specific bottlenecks like TTFB delays, render-blocking resources, and layout shift problems. The platform includes a side-by-side comparison tool that lets users measure the performance difference between two test runs, making it easy to see the exact impact of any code change. Additionally, PageGym offers an experiment tool that enables developers to test optimization strategies without altering their actual code, allowing them to quickly validate what works and what has unintended effects on performance.
Target Audience
Primary users are web developers, performance engineers, and site owners who need to diagnose, measure, and improve their website's loading speed and user experience.
