Check whether a public website is reachable over HTTPS, whether plain HTTP redirects to HTTPS and whether the secure response sends HSTS. The report focuses on transport signals the Toolmera edge can verify directly.
Free SSL and HTTPS checker for live HTTPS reachability, HTTP-to-HTTPS redirect behavior, final secure URL and Strict-Transport-Security headers.
Toolmera attempts the requested HTTPS connection through the edge network and confirms the final scheme and HTTP response. For HTTPS targets it also tests the equivalent HTTP URL to see whether traffic is upgraded to HTTPS through the redirect chain.
The checker reports the Strict-Transport-Security header when present. HSTS tells compatible browsers to prefer HTTPS for the host after the policy has been received over a valid secure connection.
A site can support HTTPS while still serving an HTTP version separately. Redirecting HTTP traffic to the canonical HTTPS URL reduces duplicate entry points, helps users land on the secure version and keeps internal linking and canonicalization simpler.
After enabling HTTPS, test representative URLs rather than only the homepage. Mixed redirect rules, old subdomains and application-specific paths can behave differently.
The current Toolmera edge fetch confirms that a trusted HTTPS connection can be established, but it does not expose the remote certificate issuer, serial number or expiry date to this application layer.
Instead of inventing certificate metadata, the tool explicitly limits its report to verifiable HTTPS, redirect and HSTS signals. A future certificate-specific backend can add issuer and expiry data if a reliable TLS inspection source is introduced.
Use the SSL Checker to check HTTPS on a public website and verify the transport-security signals visible from the live response. Toolmera reports whether the HTTPS version is reachable through a secure connection, whether an HTTP request redirects to HTTPS when that check is available, and whether the final HTTPS response sends an HSTS header.
These checks answer practical deployment questions such as whether visitors can reach the site securely and whether HTTP traffic is upgraded to HTTPS. They do not replace certificate-chain forensics, vulnerability scanning or a full TLS configuration audit.
Use the public host whose HTTPS and transport behavior you want to verify.
Toolmera confirms the final secure scheme, tests HTTP-to-HTTPS redirect behavior and reports Strict-Transport-Security when present.
Use the verified HTTPS signals here and a certificate-specific service when you need issuer, chain or expiry metadata.
Reference material used for this page:
Yes. It checks public HTTP and HTTPS transport signals without an account.
Not currently. The edge fetch interface used by this tool does not expose the served certificate expiry, so Toolmera does not fabricate it.
HSTS tells compatible browsers to use HTTPS for the host for the policy duration after receiving the header over a secure connection.
It confirms whether users entering an insecure URL are redirected to the secure HTTPS version.
No. HTTPS protects transport. Application security also depends on authentication, authorization, software updates, headers and secure code.
