Website Grader

Grade any public URL across SEO, performance, mobile-readiness, and security. Heuristic and DOM checks with a clear score and the fixes that matter. Nothing is stored.

Input

Website URL

Public URLs only. Fetched server-side via /api/fetch-page, no cookies or credentials passed. Header-only checks (HSTS, CSP headers) are not available from a fetch, so the Security grade reflects what is visible in the HTML.

Paste the page's HTML (view source, copy all)

Report

Enter a URL or paste HTML, then grade the website.
