Qualys SSL Checker Alternative

Qualys hosts the popular SSL Server Test at SSL Labs — a thorough TLS audit that often takes one to two minutes per host. HTTPS Checker is a free Qualys alternative when you need the full HTTPS picture fast: grade, certificate expiry, redirect chain, security headers, HTTP/2 and HTTP/3, mixed content, CAA and DNSSEC.

For cipher-level compliance reviews, Qualys remains the gold standard. For everyday deploy checks, see our HTTPS Checker vs SSL Labs breakdown.
