VigilDNS

Free typosquat checker

Enter your domain and we will generate its lookalike permutations (typos, homoglyphs, swapped letters, TLD swaps and more) and check which ones are registered right now. Domains with mail servers are flagged: they can send email that impersonates you. No signup, no credit card.

What this tool checks

The free check is a snapshot of resolving domains only. The full platform also tracks dormant registrations (registered but serving no DNS, verified against the registry), certificate issuance in real time, page content and clone scores, risk scoring, and change history. Learn more about the threat in what is typosquatting, or if you already found something, read what to do when someone registers a lookalike of your domain.

Frequently asked questions

Is this really free?

Yes. No account, no email, no credit card. We limit scans per visitor to keep the service fast for everyone.

Why do some registered lookalikes not appear?

The free check tests the most convincing permutations and only reports domains that resolve in DNS. Registered but dormant domains, and the long tail of permutations, are covered by the full platform's registry-verified scans.

A lookalike of my domain has mail servers. What now?

Treat it seriously: that domain can send email impersonating your brand. Follow the steps in our guide, someone registered a lookalike of my domain: document evidence, report to the registrar and host, warn staff, and put the domain under monitoring.
