How to use the Suspicious Link Checker

Paste a suspicious URL to inspect the visible hostname, real domain structure, Punycode form, hidden Unicode characters, and common spoofing indicators. The analysis runs locally and does not open or fetch pasted URLs.

What this checks

  • Flags credentials in the URL, misleading subdomains, and encoding tricks.
  • Shows the hostname and Punycode details without opening the link.
  • Works with a trusted-domain comparison when you need one.

When to use it

  • A link arrives in email or chat and you want a quick trust check.
  • You suspect the hostname is hiding a brand inside a longer domain.
  • The URL has odd encoding, percent escapes, or username/password text.

How to use it

  1. Paste the suspicious link into the input.
  2. Optionally add a trusted domain for comparison.
  3. Run Analyze locally and review the URL and domain evidence.
  4. Use the report export buttons if you need to share the findings.
