RoastWeb vs Google PageSpeed Insights
A comprehensive, honest comparison to help you choose the right tool
Google PageSpeed Insights is the industry-standard tool for measuring website performance. It's free, powerful, and backed by Google's infrastructure. So why would you use anything else?
The answer is simple: PageSpeed Insights is excellent at what it does, but it only does one thing. It focuses exclusively on performance metrics like Core Web Vitals, load times, and resource optimization.
RoastWeb takes a different approach. We provide comprehensive website auditing across 15+ categories including performance (using the same Lighthouse engine as PageSpeed), plus SEO, accessibility, security, content quality, and AI-powered insights. Think of PageSpeed as a specialized diagnostic tool, and RoastWeb as a complete health checkup.
