When deploying a new website or setting up custom domains, verifying that your SSL/TLS certificate is properly configured is critical. This SSL Checker is built to give developers a fast, transparent way to audit certificate chains and expiration dates directly from the browser.
WebSockets and Fetch API
The tool utilizes a combination of backend probes and frontend APIs to query the target domain, extracting the raw X.509 certificate data. It parses the issuer, validity periods, and SANs (Subject Alternative Names) to give you a clear diagnostic report.
