Website Health Checker

One check, the whole picture: availability, HTTP status, response time, headers, security configuration, TLS, DNS and domain data — composed into a single health verdict with links to the detailed tools.

What the check covers

Website Health runs one safe HTTP request plus the DNS, TLS and domain lookups, then summarizes each area as a single check with a state and a key measurement:

  • Availability and HTTP status — is the site reachable, and what does it answer (including the final URL after redirects)?
  • Response time — how fast did it answer (single sample; the Response Time Checker adds multi-sample detail)?
  • Headers and security configuration — the notable security headers, cookie flags and TLS facts, reviewed the same way the Security Checker reviews them.
  • TLS certificate depth, DNS record families and — for domains — registration and expiry data via the Domain Overview engine.

How to read the states

Each check reports pass, warn, fail or unknown; the overall verdict combines them: any failure means ERROR, incomplete evidence means PARTIAL, otherwise warnings mean WARNING, and a fully passing set means HEALTHY. Every completed row links to the standalone tool that owns the deeper data.

What this check does not do

It is not a vulnerability scanner and it never asserts that a site is “secure” — findings describe the configuration observed during the check only. It does not monitor your site over time, and it does not index results per target.
