AcuityScan vs PageSpeed Insights

PageSpeed Insights is the canonical, free source for Core Web Vitals. AcuityScan reads that same data and scores it next to seven other categories.

PageSpeed Insights (PSI) is Google's own free tool, and it's the reference for Core Web Vitals and Lighthouse performance scoring. AcuityScan actually pulls performance data through PSI, so the speed numbers line up. The difference is scope: PSI tells you about speed; AcuityScan folds speed into a full-site health score alongside email, security, SEO, accessibility, privacy, and mobile.

A plain-English fix and shareable report for every finding across all eight categories.

When PageSpeed Insights is the better choice

We would rather you pick the right tool than the wrong one. PageSpeed Insights is the better fit when:

You only need Google's official Core Web Vitals number for one page and nothing else.
You want the canonical PSI score to cite directly, for free, with no account.
You are debugging a single performance metric and want Google's raw Lighthouse output.

Questions

Does AcuityScan use PageSpeed Insights data?

Yes. AcuityScan's performance module pulls Core Web Vitals and Lighthouse performance data through Google's PageSpeed Insights, so the speed numbers are consistent. We add TTFB, compression, CDN detection, and a technology-stack scan on top.

If PSI is free, why pay for AcuityScan?

PSI only measures speed. AcuityScan scores speed next to email authentication, SSL, DNS, SEO, accessibility, privacy, and mobile, with fixes and monitoring. If speed is genuinely all you need, PSI is great and free.

Does AcuityScan run Lighthouse?

Performance and accessibility use industry-standard engines (Google PSI for performance, axe-core for accessibility). The result is comparable to Lighthouse on those axes, inside a broader audit.
