Bulk SSL Checker: How to Check Multiple Domains at Once
When you manage more than one site, checking HTTPS and SSL one domain at a time gets old fast. A bulk SSL checker lets you run the same checks on several domains in one go and see grades, redirect chains, and certificate details side by side. Here's how our tool does it and how you can use it.
Key takeaways
- You can check up to 10 domains in a single run. Enter them in the box, comma or space separated.
- Each domain gets the full check: HTTPS availability, redirect chain, SSL certificate, grade (A+ to F), security headers, HTTP/3, mixed content.
- Results can be exported to PDF or JSON. Each domain also gets a stable report link you can share or bookmark.
- No account needed. Free, no signup. Same checks as the single-domain flow.
Who uses a bulk SSL checker?
Developers and ops teams with a handful of sites want a quick overview without opening a dozen tabs. Agencies that maintain client sites need to spot expiring certs or broken redirects before clients do. Even if you only have two or three domains, pasting them once and getting one report page is often easier than running the checker three times. The limit of 10 keeps the run fast and the results easy to scan.
How to run a bulk check
On the homepage, in the checker box, type or paste your domains. Separate them with commas or spaces. You can mix both. For example: example.com, example.org, sub.example.net. The tool will trim whitespace and ignore empty entries. Once you hit the limit of 10 domains, any extra are skipped and you'll see a short note. Click the check button and wait a few seconds. Results appear in a list: each row shows the domain, grade, whether HTTPS works, redirect status, and a link to the full report.
Export and share
From the bulk results you can export the whole set to PDF or JSON. The PDF is a single document with one section per domain, suitable for audits or handoffs. The JSON is the same data in machine-readable form for scripts or dashboards. Each domain in the list also has a permanent report URL. Open it to see the full single-domain report (redirect chain, certificate details, security headers, and so on). You can share that link with a colleague or drop it into documentation. Reports are stored so the link keeps working.
Check multiple domains now
No signup, no account. Enter up to 10 domains in the box and run the check. You get the same SSL grade, redirect chain, and certificate info we use for single-domain checks.
