URL Link & Reachability Checker

Inspect web link syntax, verify HTTPS encryption, check HTTP response status codes, and test destination reachability.

Scope Notice: This tool performs structural syntax inspection, protocol verification, and HTTP reachability testing. It is not an antivirus engine or malware certification provider.

Why Perform Pre-Flight Link Inspections?

Before sending promotional campaigns, publishing documentation, or embedding web links into marketing emails, verifying destination syntax and HTTP reachability prevents broken user journeys, 404 dead-ends, and damaged sender reputation.

URL Syntax Validation

Detects missing protocols, unencoded spaces, malformed query parameters, and invalid port specifications.

Transport Security

Confirms whether the destination enforces HTTPS TLS encryption or downgrades to unencrypted plaintext HTTP.

Server Reachability

Verifies that the target host returns an active HTTP 200 OK or legitimate redirect rather than a broken 404 or 500 error.

The Link Checker evaluates URL syntax compliance (RFC 3986), transport protocol encryption (HTTPS vs HTTP), destination port numbers, DNS reachability, and HTTP response status codes without running client-side code.
