GTmetrix for diagnostics, Kuality for prevention
GTmetrix gives you the best waterfall chart and filmstrip when you are debugging a specific performance issue. Kuality is for preventing that issue from shipping — by gating CI/CD on LCP budgets, tracking scores across every deployment, and bundling accessibility and security into the same automated scan.
Performance budgets
Set LCP, CLS, and INP thresholds. Kuality's gate API returns 422 when a deployment pushes metrics past your budget — before it hits production.
Deploy-by-deploy tracking
GTmetrix shows today's score. Kuality shows the score on every deploy, so you can pinpoint exactly which PR introduced the 400ms LCP regression.
Beyond performance
GTmetrix is speed-only. Kuality adds WCAG accessibility, security headers, cookie compliance, and broken links in the same scan — one platform, one dashboard.
