How do I check SSL for multiple domains at once?

Paste your list of domains, one per line, and this free bulk SSL checker checks the SSL certificate and domain registration for every one at once — no signup — then sorts anything expiring or broken to the top.

How many domains can I check at once here?

This free tool checks up to 20 domains per run — enough to spot-check a client or a project. To watch your whole portfolio on a schedule, monitoring covers every domain you add with daily checks and alerts.

Does it check domain expiry too, or only SSL?

Both, side by side. For each domain you get the SSL certificate's expiry and validity and the domain-name registration's expiry — the two dates that quietly lapse and take a site offline — in one plain-English row.

Bulk SSL & Domain Checker

Check multiple SSL certificates at once: paste your domains, one per line, and we'll check the SSL certificate and the domain registration for each — then sort anything that needs attention to the top.

How it works

Paste your list

Paste your domains one per line, or import a list — up to 20 hostnames in a single free check.

We check each one

For every domain we check the SSL certificate and the domain-name registration, and translate the result into plain English.

Problems at the top

Anything expiring soon or already broken is sorted to the top, so you see what needs attention at a glance.
