HTTPS Checker vs SSL Labs
Qualys SSL Labs (SSL Server Test) is the gold standard for deep TLS analysis — and we say that without irony. But most site owners don't need a two-minute cipher-suite audit; they need to know in seconds whether the redirect, certificate, headers and protocols are configured correctly. Here is an honest comparison so you can pick the right tool for the job.
Feature comparison
| Feature | HTTPS Checker | SSL Labs |
|---|---|---|
| Typical scan time | Seconds | 1–2+ minutes |
| SSL/TLS grade (A+ to F) | Yes | Yes |
| Certificate validity & expiry | Yes | Yes |
| Deep cipher-suite & TLS vulnerability testing | No | Yes |
| Client handshake simulation | No | Yes |
| HTTP → HTTPS redirect chain | Yes | No |
| Security headers (HSTS, CSP, …) | Yes | No |
| Mixed content detection | Yes | No |
| HTTP/2 & HTTP/3 (QUIC) detection | Yes | HTTP/2 only |
| CAA record check | Yes | Yes |
| DNSSEC validation | Yes | No |
| Bulk check (multiple domains) | Up to 10 | No |
| SSL expiry reminders / monitoring | Yes | No |
| Export report (PDF / JSON) | Yes | No |
| Free public API | Yes | Rate-limited |
| Signup required | No | No |
Use HTTPS Checker when…
- You want a full HTTPS health check — redirect, certificate, headers, HTTP/2/3, mixed content — in one fast report.
- You manage several sites and want to bulk-check up to 10 domains at once.
- You need expiry reminders, monitoring, or a JSON API for CI pipelines.
- You want a shareable report link or PDF for a client or your team.
Use SSL Labs when…
- You need an exhaustive audit of every cipher suite and TLS version your server accepts.
- You are testing for specific TLS vulnerabilities (ROBOT, POODLE, Heartbleed, …) for compliance.
- You want handshake simulations against dozens of legacy clients.
- Scan time doesn't matter — depth does.
Frequently asked questions
Is HTTPS Checker a replacement for SSL Labs?
For everyday checks, yes — you get an SSL grade, certificate and expiry, redirect chain, security headers, HTTP/2/3, mixed content, CAA and DNSSEC in seconds. For deep cipher-suite auditing and TLS vulnerability testing, SSL Labs goes deeper and is worth the wait.
Why is SSL Labs so slow?
It tests every protocol version and cipher suite and simulates handshakes for dozens of clients — thoroughness that typically takes one to two minutes or more per host. We test what most site owners need day-to-day, which is why our results arrive in seconds.
Does SSL Labs check security headers or redirects?
No — SSL Labs focuses on the TLS configuration itself. It does not analyze HTTP security headers, redirect chains, or mixed content. Our report includes all of those.
