Free link checker & phishing URL detector

Paste any link to instantly check if it is safe, phishing, or a scam. Works on shortened URLs (bit.ly, t.co), QR codes, SMS links, and DMs. No account needed.

Expands shorteners

Resolves bit.ly, t.co, tinyurl and 30+ shorteners to the real destination before scoring.

Brand impersonation

Detects letter-swap and homoglyph attacks — binnance, metarnask, ledqer — used by wallet drainers.

Community-verified

Cross-references 12,000+ confirmed scam entries plus live reports from the GACS community.

How the GACS link checker works

Paste a URL and the scanner runs the same checks a fraud analyst would, in parallel: WHOIS / registration age, TLS certificate issuer and validity, hosting ASN reputation, brand-name similarity (homograph and look-alike domain detection), content fingerprinting against known phishing kits, and a lookup against the community blacklist. You get a single verdict with the reasoning behind it — never a black-box score.

When to use a URL checker

  • A link arrived in an unexpected SMS, DM, or email.
  • A QR code in public asked you to "verify your wallet" or "claim a refund".
  • A Google Ad sent you to what looks like the real exchange — but the URL is off.
  • A "support agent" replied to your public complaint with a help link.
  • You are about to enter a password, card, or seed phrase on a site you did not type by hand.

What a green verdict actually means

Green means "no red flags found right now." It is not a guarantee. Brand-new scam domains and freshly-cloned phishing sites can land green for the first few hours until reports come in. Pair the checker verdict with the basics: never share a seed phrase, never pay an "unlock" or "tax" fee, and never trust a recovery DM.

Frequently asked questions

Is this URL safe to open?

If GACS returns green and the domain is older than 90 days, it is almost certainly safe to load in a normal browser tab. Still never enter your seed phrase, password, or card details on a page you cannot independently verify. Green means 'no red flags found right now' — not a guarantee.

What makes a URL suspicious?

Common red flags: the domain is under 30 days old, the brand name has an extra word or hyphen (binance-login, ledger-support, metamask-help), the URL uses letter swaps (rn for m, 0 for o), the page asks for a seed phrase or 'wallet validation', or the link reached you through a DM, ad, or unsolicited email.

How is this different from VirusTotal or Google Safe Browsing?

VirusTotal aggregates antivirus engines, which catch known malware files. Google Safe Browsing flags long-established phishing pages. Both miss the freshly-spun crypto scam, fake exchange, or pig-butchering broker domain registered yesterday. GACS adds crowd-sourced reports, AI text analysis of the page itself, and crypto-specific signals (drainer scripts, fake-exchange clones) that the generalists do not see.

How to check if a link is safe

  1. Copy the link without clicking it

    Long-press the link on mobile or right-click → Copy on desktop. Never tap it before scanning.

  2. Paste into the GACS link checker

    Paste the URL into the checker. Shorteners (bit.ly, t.co, tinyurl) are expanded automatically.

  3. Read the verdict

    Wait 5 seconds for a safe / suspicious / scam verdict with the exact signals behind it.

  4. Act on the result

    Green — proceed with normal caution. Anything else — close the tab and report it.
