What changed, dated

September 3, 2026

The certs. checker

  • Free check without an account: TLS certificate, six kinds of DNS records (A, AAAA, MX, NS, TXT, CNAME) and domain expiry date, in under 5 seconds.
  • Parallel checks: TLS handshake, DNS resolution and the registry (RDAP) run at the same time.
  • A clear verdict and a recommended action for each domain.
  • Unlimited domains and checks, free — no card.

The certs. report gets a grade

  • Security grade A–F with a score out of 100, computed live from six checks: expiry, chain of trust, protocol, HSTS, security headers and mixed content.
  • Shareable report link: the full result travels in the URL fragment, nothing is stored on our side.
  • Calendar reminder: download the expiry as a calendar event (.ics) with a 14-day alarm, or hand off to Heartbeat for 24/7 monitoring.
