Core Web Vitals
tested automatically.
LCP, CLS, INP, and TTFB — measured on your live site by a real browser, not simulated. Kuality surfaces what's hurting your Google ranking and your conversion rate, and lets you gate CI/CD deployments on performance budgets.
LCP exceeds Google's "Good" threshold (2.5s). Likely impacting search ranking.
Every performance metric that matters
Kuality runs a full Lighthouse audit in a real browser and surfaces the metrics Google uses for ranking and UX evaluation.
LCP — Largest Contentful Paint
Measures how long it takes for the largest image or text block to render. Google's "Good" threshold is under 2.5s.
CLS — Cumulative Layout Shift
Quantifies unexpected layout shifts during page load. Scores above 0.1 frustrate users and hurt rankings.
INP — Interaction to Next Paint
Google's newest Core Web Vital. Measures responsiveness to user input — clicks, taps, and keyboard events.
TTFB — Time to First Byte
Server response latency. Identifies slow origin servers, misconfigured CDNs, and render-blocking backend calls.
Performance Budgets
Set LCP / CLS / INP thresholds and fail CI/CD when a deployment pushes metrics past your budget.
Score Trend
Track your performance score across deployments to catch regressions the moment they're introduced.
Block bad deploys. Protect your ranking.
Performance is part of Kuality's all-in-one quality platform — alongside accessibility, security headers, broken links, and uptime. One scan covers them all.
