Heads up: this tool runs heuristic checks, not authoritative audits. For production decisions pair it with real-user field data (Chrome UX Report / PageSpeed Insights) and a manual code review.

Mentions of Google, Cloudflare, Netlify, Vercel, Fastly, Microsoft Clarity, Ahrefs, SEMrush, Sitebulb, Moz, and similar products are nominative fair use — no affiliation implied.
