Free website diagnostic
Check the public surface before changing production.
Enter a website you are authorized to manage. The check reads public domain infrastructure and the homepage, then returns a bounded snapshot without crawling the site.
DNS, availability and HTTPS
Public DNS, redirect, certificate, protocol, and homepage response.
Mobile, metadata and structure
Viewport, canonical, social metadata, headings, labels, icons, and structured data.
Browser and transport baseline
Protection headers, cookie transport, mixed content, forms, and security contact signals.
Delivery and platform context
HTML weight, compression, cache, third parties, analytics, consent, commerce, and CMS markers.
Maximum 10 bounded HTTP requests, DNS lookups, and one TLS handshake. No login, exploit attempt, checkout submission, account creation, broad crawl, or private-data access is performed.
