Yes. The checker is free and you don’t need an account or signup. Enter one domain or several (up to 10, comma or space separated) for a bulk check. You get the full report—redirect chain, certificate, grade, headers, mixed content. You can export to PDF or JSON and share the results link. No registration required.
When a check succeeds (the domain is reachable over HTTPS and not rate-limited), we store the domain and result so you get a stable report page you can share at /report/{domain}. We don’t tie stored reports to you personally. We don’t store results for unreachable domains or when the server returns 429. Server logs may temporarily hold request data for operations and security; we don’t use them to identify you or build profiles. See our Privacy page for full details.
We look at eight things: HTTPS works (25 pts), redirect in place (20), valid certificate (20), cert not expiring in 30 days (10), response under 1 second (10), redirect chain of 3 hops or less (5), HSTS on (5), and security headers (5). 98+ A+, 88+ A, 85+ A-, 75+ B+, 65+ B, 45+ C, below 45 F. A+ also requires HSTS preload, CSP, TLS 1.3. The report shows which bits you’re missing.
