Problem

Websites suffer from slow load speeds, high TTFB, render-blocking resources, and layout shift issues, which degrade user experience and search rankings. Developers and site owners lack an easy way to measure these problems, verify the impact of changes, or test optimizations before committing code changes.

Solution

PageGym provides a suite of performance testing and optimization tools that help users measure website speed and identify specific technical issues. The platform supports side-by-side test comparisons, showing the performance difference between earlier and current tests to help users understand the exact impact of their changes. Its built-in experiment tool allows users to test optimization strategies without modifying their code, making it safe to try what works and detect harmful side effects before implementation.

Target Audience

Primary users are web developers, performance engineers, and site owners who need to diagnose, optimize, and validate website speed improvements through empirical testing.

Features

Website speed testing with TTFB detection and identification of render-blocking resources
Layout shift problem detection to catch visual instability issues
Comparison tool for side-by-side performance analysis against earlier test results
Experiment tool to run optimization tests without code changes, revealing both positive and negative effects
Historical test storage for tracking performance changes over time
