Free Domain Health Check
One check for the three things that take sites down silently: SSL expiry, domain expiry and DNS. Enter a domain to see them all at once.
What we check
SSL certificate validity and days to expiry; domain registration expiry and registry status; and live DNS records (A, AAAA, MX, NS, TXT). Together these cover the most common silent failures behind an outage.
From one-off check to always-on
This is a snapshot. The failures it surfaces happen on their own schedule, with no warning. Lapseguard runs these checks continuously across all your domains and alerts you before anything lapses.
Questions, answered
- Does this store my domain?
- No — it runs a one-off check and returns the result. Nothing is saved unless you start monitoring it.
- Why might the SSL section say it was skipped?
- We only open a TLS connection to public hosts. For a private or non-public address we skip the SSL check and still show expiry and DNS.
- How do I keep watching all three?
- Start monitoring the domain in Lapseguard — SSL, expiry and DNS, with email and Slack alerts before anything breaks.
