05. Questions
Frequently asked questions
How does WebVyze measure real visitors?
A script of about 10 KB (gzip), loaded with defer, uses Google's web-vitals library to measure LCP, INP, CLS, TTFB and FCP in your visitors' browsers. It also records the element and cause behind each poor metric. Figures are the p75, as Google reports them, weighted by sampling.
How is this different from PageSpeed Insights?
PageSpeed shows a lab test and, when there is enough traffic, the origin's Chrome data (CrUX). WebVyze measures the pages where the script runs, on your own visitors, tells which element and which part of the time weigh most, marks deploys and warns you when something gets worse. The lab test is still there, per page.
Which laws and standards does WebVyze check?
Accessibility: WCAG 2.0, 2.1 or 2.2 level AA (chosen per site), the ADA, the European Accessibility Act, and Brazil's LBI and NBR 17225. Privacy: GDPR and LGPD, including trackers and cookies that fire before consent. Payments: PCI DSS 4.0 requirements 6.4.3 and 11.6.1 for scripts on checkout pages. WebVyze suggests the laws for each site from its domain, language and checkout, and you record why each one applies.
Does WebVyze change my website?
No. WebVyze only reads public pages, like a visitor. It is not an overlay or widget that rewrites the page on top: fixes are made in your code by your team or your AI agent, and WebVyze verifies them afterwards.
How does WebVyze work with AI coding agents?
WebVyze has an MCP (Model Context Protocol) server. Claude Code, Cursor and other MCP clients connect with an account token and can list issues prioritized by legal risk, read the fix guide and the evidence, and request a verification once the fix is deployed.
How is a fix verified?
WebVyze re-checks only the URLs and the rule of that issue and records the evidence: selector, header, measurement or screenshot. Without that evidence the issue is not marked as resolved. Criteria that automation cannot judge are flagged for human review.
Is an automated check enough to be compliant?
No. Automated results indicate risk; they are not a certification or legal advice. Part of WCAG and of each law needs manual testing and legal review, and WebVyze shows which items those are.
How much does WebVyze cost?
There is a free plan for one site and a free law check without sign-up. Paid plans are priced in US dollars by number of sites, and audits and verifications use credits. See the pricing page for current plans.
