URL Safety Analyzer

Analyze any URL for phishing, suspicious patterns, and security risks. Detects login keywords, suspicious TLDs, encoded characters, brand impersonation, and more

Before you click a suspicious link, paste it here. This analyzer inspects the URL structure for common phishing patterns, homoglyph attacks, suspicious redirects, and known-bad TLDs. It won't visit the URL, it analyzes the string itself.

URL Safety Analyzer: a worked example

A "your account is locked" email links to the URL below and you want a sober breakdown before anyone in the team clicks it.

URL pasted

http://paypa1-secure-login.account-verify.ru/login?next=update
URL Safety Analyzer produces

Risk findings

⚠ Lookalike brand: "paypa1" substitutes 1 for l (typosquat)
⚠ Not HTTPS: credentials would be sent in clear text
⚠ Real domain is account-verify.ru, not paypal, brand is only a subdomain
⚠ Credential keywords: "secure-login", "verify"
Verdict: High risk, classic phishing structure

The analyzer inspects the URL lexically, it never visits the link. It separates the true registrable domain (`account-verify.ru`) from the deceptive subdomain, flags homoglyph/typosquat tricks like "paypa1", and notes the missing TLS. This is structural phishing detection, so treat it as a strong warning, not a substitute for a live threat-intel blocklist.

Frequently asked questions

No. It only analyzes the URL string. No HTTP requests are made to the target.

Can it catch every phishing attempt?

No tool can guarantee 100% detection. This catches structural patterns, but always exercise judgment with unfamiliar links.
