🔐 SSL Certificate & DNS Checker — expiry, issuer, DNS records

Check many domains at once: SSL certificate validity, expiry date and days left, issuer, TLS version and the DNS records (A, AAAA, MX, NS, TXT, CNAME, SOA, CAA). Catch expiring certificates before your sites break. $1 per 1,000 domains.

✅ Status per domain: ok, expiring soon, expired, ssl problem
✅ Choose how many days before expiry you want a warning
✅ Certificate subject names (SANs), issue and expiry dates
✅ Handles bad certificates: reports the problem and still reads the dates
✅ Schedule it daily and connect alerts (Slack, e-mail, Make, n8n) to monitor a whole portfolio

How to use it

Paste your domains (one per line).
Pick DNS records and the warning days.
Run (or schedule) and filter rows where status is not ok.

Output example

{
  "domain": "github.com",
  "sslValid": true, "sslDaysLeft": 112, "sslExpires": "2027-01-30",
  "sslIssuer": "Sectigo Limited", "tlsVersion": "TLSv1.3",
  "a": ["140.82.121.4"], "mx": ["1 aspmx.l.google.com"],
  "status": "ok"
}

Pricing

$0.001 per domain checked ($1 per 1,000). Domains that do not exist are free.

Notes

Only port 443 is checked. Private/internal addresses are blocked.
DNS answers come from public resolvers and can differ by region.
