Lookalike domain checker

Enter your domain to see which lookalike versions of it are registered right now, and which of them look risky.

Free, no account needed. A scan takes 15 to 60 seconds. You get a shareable result link.

What the check looks at

• Variations of your name: missing, doubled, swapped and neighbouring-key letters, single-bit errors, hyphens, look-alike characters (including Unicode/IDN), other extensions such as .net or .co, and your name with words like "login", "support" or "pay".
• New certificates: domains containing your name that recently got a TLS certificate, from public Certificate Transparency logs.
• For each registered lookalike: DNS (website, mail servers), registration date and registrar from RDAP, and a look at the web page: does it mention your brand, copy your page title or icon, or show a login form?

How results are scored

Each lookalike gets a score from 0 to 100 built from listed reasons, for example "+15 has mail servers" or "-40 redirects to your own site". The reasons are shown next to every result so you can judge them. The scoring rules are on How it works.

What it does not do

LookalikeGuard is monitoring and early warning. It does not take down domains, send legal notices, or give legal advice. Scores are automated and can be wrong in both directions: a high score is a reason to look, not proof of abuse. Many lookalike domains are parked, owned by unrelated businesses, or registered defensively by the brand itself; you can mark those as yours or dismiss them.
