Check Any Web URL Instantly for free.
Check Url diagnostics dissect the full anatomy of any website. We analyze hosting infrastructure, HTTP status behavior, and security signals, uncovering misconfigurations, unsafe elements, and hidden issues across the entire request path.
Stop malicious links
before you click.
Powerful, free link diagnostics built directly into your browser workflow.
Trace Every Hop
See exactly where a link goes. We follow every redirect to expose hidden tracking and malicious destinations.
SSL Verification
Confirm if a website's security certificate is valid, trusted, and up to date before you share any data.
Security Scans
Instant checks against global databases like VirusTotal to flag phishing and malware threats automatically.
100% Private
We visit the site for you. Your IP address and location are never exposed to the target server during the check.
How Check Url works under the hood - 100% free.
We don't just fetch the page. We execute a deep native trace to pull server-level metadata that typical browsers hide.
Concurrent Safety Scanning
Our engine executes simultaneous security checks against global databases including VirusTotal and Google Safe Browsing to flag malware, phishing, and known malicious domains instantly.
Deep TLS/SSL Inspection
We perform a full cryptographic handshake with the origin server to extract the raw x.509 certificate. This reveals the true issuer, encryption standard, and absolute validity dates.
Recursive Redirect Mapping
When a URL hide behind trackers (301/302 redirects), we intercept and recursively trace every hop until the final destination is reached, constructing a complete map of the chain.
