webzod: website security and quality checker

Enter a domain and watch the checks run in a live console. Passive checks only: DNS queries, a TLS handshake and the requests a browser would make.

What it checks

• Security

  TLS configuration, HTTP security headers and known-vulnerable software.

• Email

  SPF, DKIM, DMARC and MTA-STS, so forged mail from your domain is rejected.

• DNS

  DNSSEC, nameserver health, CAA records and dangling subdomains.

• Performance

  Core Web Vitals from lab and real-user data.

• SEO

  Indexability, titles, canonical URLs and structured data.

• Accessibility

  Automated accessibility audits of the page a visitor lands on.

• Hygiene

  security.txt, robots.txt, sitemap and crawler policy.
