Bulk domain + SSL expiry checker
Paste up to 10 domains, one per line or comma-separated. For each one you'll see when the domain and its SSL certificate expire.
Domain dates only, for up to 25 domains? Try the bulk domain expiry lookup.
What you get for each domain
- Domain expiry date and days left, from the registry (RDAP/WHOIS)
- Registrar
- Served SSL certificate expiry and days left
- Certificate issuer and whether the chain is trusted
Frequently asked questions
What does this checker look up?
Two separate expiry dates: the domain registration's expiry from the registry (RDAP, with a WHOIS fallback), and the expiry and issuer of the SSL/TLS certificate the site actually serves on port 443. If the bare domain doesn't serve a certificate, we try www.
Why are the domain and SSL dates different?
They're renewed separately. A domain is usually renewed yearly at the registrar; public SSL certificates last at most 200 days since March 2026, and many renew every 60–90 days automatically.
Is it free? Are there limits?
Yes, no signup. Each network gets 20 single checks and 5 bulk checks (up to 10 domains each) per hour.
Do you store the domains I check?
No. Lookups aren't saved to an account. Rate limiting keeps a short-lived per-network counter for one hour.
