Domain health checker
Check a domain in one pass.
One report for certificate, registration, DNS, email, headers, hosting, history, subdomains and reputation — designed to be useful at a glance, not flashy.
Certificate, DNS, email, headers, hosting, history, subdomains and reputation in one report.
Instant browser checks with no signup required for quick manual lookups.
Use the same schema for automation, internal tooling and higher-volume monitoring.
Coverage
What DomainClock checks
Each row opens a dedicated page with deeper detail. The homepage keeps the summary short and scannable.
TLS certificate
Expiry, issuer and certificate validity.
Registration
Registrar, age and domain expiry.
DNS
A, AAAA, MX, NS, TXT, CAA and SOA records.
Email security
SPF, DKIM, DMARC and MX posture.
Server
Status, redirects, response time and protocol.
Security headers
CSP, HSTS and browser-facing protections.
Hosting
Public IP, ASN, provider and location.
History
Wayback capture dates and archive context.
Subdomains
Public names seen in Certificate Transparency.
Reputation
Threat-list and abuse signals from public sources.
Use cases
Built for practical checks, not dashboard theatre
Catch renewal and DNS surprises early
See the certificate, registration expiry, DNS posture and mail records in one pass before the next incident ticket appears.
Give support and ops the same picture
A report can be shared across engineering, support and client handoff work without asking each person to run a different tool.
Move from manual checks to code
The same report structure is available as an API when you want alerts, internal tooling or scheduled monitoring.
Use the same report in code
Start with the browser, then move to the API when you want higher quotas or internal automation.

Take the same schema to your workflow
The API returns the same blocks you see on the site, so you do not need a second mental model when you automate checks.
