It generates domain name variations that could be used for phishing or typosquatting attacks — common misspellings, homoglyphs, and similar-looking domains — so you can proactively protect your brand.
How do I use it?
Enter your domain name and the tool generates variants using techniques like character swapping, homoglyphs, insertion, deletion, and TLD changes. You can then check if any are registered.
What attack types does it cover?
It covers typosquatting (misspellings), homograph attacks (Cyrillic lookalikes), bit-squatting (single-bit errors), combo-squatting (keyword insertion), and TLD variations (.com vs .net).
Can I check if variants are registered?
Yes. The tool can perform WHOIS lookups on generated variants to identify which domains are already registered, helping you prioritize defensive registrations.
