Free Bulk SSL & Redirect Checker
When does each certificate expire? Do browsers trust it? Does every version of the address (http, https, www, no www) end up on the same secure page? Check up to 20 domains at once.
Quick human check, then the tool unlocks:
What this checker shows
- Certificate expiry: the date and how many days are left. Anything under 14 days is flagged.
- Trust: whether browsers accept it, and why not if they don't (expired, wrong name, self-signed or a missing intermediate certificate).
- Details: issuer, every name it covers, key type, TLS version and the certificate chain.
- Redirects: where
http://,https://,www.and no-www each end up, step by step. Ideally all four land on one secure address in a single step. - HSTS: whether the site tells browsers to always use HTTPS.
🔒 The domains you check are not saved or logged.
