AcuityScan vs GTmetrix
GTmetrix is a solid, focused page-speed tool. AcuityScan measures performance too, then adds the seven other things that decide whether a site is actually healthy.
GTmetrix is a clean, well-known performance tool with helpful waterfall charts and historical tracking on its paid plans. If page speed is the only metric you're chasing, it's a fine choice. AcuityScan measures Core Web Vitals through the same Google data source, then scores performance next to email, security, SEO, accessibility, privacy, and mobile so a fast-but-broken site can't hide behind a good speed grade.

Where AcuityScan goes further
- Seven categories GTmetrix does not assess: email, DNS, SSL/TLS, full SEO, accessibility, privacy, and mobile.
- Performance scored alongside everything else, so a fast page with broken email or no DMARC still shows up.
- A real axe-core accessibility audit and a tracker/privacy scan in the same run.
- Plain-English fixes and a shareable report for every category, not just speed.
When GTmetrix is the better choice
We would rather you pick the right tool than the wrong one. GTmetrix is the better fit when:
- Page speed is the only thing you're optimizing and you want a dedicated speed dashboard.
- You rely on GTmetrix's specific waterfall view or its low-cost speed-only monitoring at $11/mo.
- You want repeated speed tests from a specific test location and device profile.
