Performance & UX
What your users actually get, measured in a real browser.
Core Web Vitals Monitoring
Load your page in a real browser on a schedule and track LCP, CLS, FCP, TTFB and TBT over time — get alerted when LCP or CLS cross Google's thresholds.
Lighthouse Monitoring
Scheduled Lighthouse audits — Performance, Accessibility, Best Practices and SEO scores tracked over time, with an alert when a score drops below your minimum.
Accessibility (WCAG) Monitoring
Scheduled axe-core audits of your page against WCAG 2.x A/AA in a real browser — violated rules by impact and affected elements, with an alert when critical issues appear.
Screenshot Monitoring
Scheduled visual snapshots of a page, diffed pixel-by-pixel against the previous one to catch a change nothing else picks up on.
