Detect lookalike domains that could be used for typosquatting or brand impersonation targeting your domain name.
Typosquatting detection via omission, transposition, replacement, insertion, homoglyph substitution, hyphenation, and more.
WHOIS, DNS, Safety Check, and more to analyze a domain across multiple dimensions.
What is Typosquatting
Typosquatting is the practice of registering domain names that closely resemble an established domain: a swapped letter, a missing character, a lookalike glyph, or the same name on a different extension. These lookalike domains are commonly used for traffic interception and brand impersonation, making typosquatting detection an essential part of any brand protection strategy.
This typosquatting checker generates permutations of your domain across 11 mutation types and checks which ones are currently registered. Think of it as a modern dnstwist alternative with a web interface: no command line required, results stream in with registration status, and you can drill into WHOIS and DNS for each lookalike domain directly from the results.
How to Read the Results
Each result shows the permutation, which extension it uses, how many TLD extensions that name exists on, the mutation type, and its registration status. For any registered lookalike, run a WHOIS lookup to see its registration dates and status codes, check its DNS records to see whether it resolves to live infrastructure, or use the inline Check panel to view both without leaving the page. To check one name across 1,200+ extensions at once, use Bulk TLD Check.
Defensive Registration for Brand Protection
Most brands cannot register every permutation, and they do not need to. Prioritize the variants with the highest confusion risk: single-character typos of your exact name, homoglyph lookalikes, and your exact name on major extensions such as .com, .net, .org, .io, and .ai. Securing high-risk variants while they are still available is typically far cheaper than recovering them later through dispute proceedings.
Catch New Lookalikes as They Appear
A typosquatting scan is a snapshot of what exists today. New lookalike domains get registered every day, so the more useful question is what is being registered right now. Search your brand across newly registered domains to see every name containing your keyword that was registered in the past 60 days, filter by registration date, and spot infringing registrations while they are still fresh. Running that search periodically turns a one-time scan into ongoing domain brand monitoring.
Frequently Asked Questions
What is a typosquatting scanner?
A typosquatting scanner is a detection tool that generates variations of a domain name using common typo and impersonation patterns. It checks each variation against domain databases to see if it is registered, helping you identify lookalike domains that could be used for brand impersonation. It works similarly to dnstwist but with a web interface and built-in registration status checking.
What mutation types are used?
The scanner uses 11 mutation types: character omission, transposition (swap), keyboard-adjacent replacement, character insertion, repetition (doubling), hyphenation, vowel swap, homoglyph substitution, plural/singular variation, exact-match TLD checks, and common TLD swaps.
Which TLDs does the scan cover?
Spelling variations (typos, homoglyphs, vowel swaps, and the like) are checked on the same extension you entered, so scanning example.com looks for lookalikes ending in .com. On top of that, your exact name is also checked on a set of major extensions, including .com, .net, .org, .io, .co, .ai, .app, and .dev, to catch the same brand registered on a different TLD. To check one name across 1,200+ extensions at once, use the Bulk TLD Check.
Do I need an account?
Guest users can run 1 scan per day with up to 20 results shown. Creating a free account gives you 3 scans per day with full results. Lite and Premium members get higher daily limits.
How is registration status checked?
Each permutation is checked against domain registration databases. Domains are classified as registered, available, or expired. Results stream in as they are verified.
Does a mutation result mean trademark infringement?
No. A permutation scan identifies spelling relationships between domain names, not legal violations. A domain appearing in the results only means it is structurally similar to the input. Whether a registration constitutes infringement depends on context, intent, and applicable trademark law. This tool does not provide legal advice.
Common dictionary words, personal names, short phrases, and short character strings are generally not suitable targets for brand infringement claims. These are part of everyday language and many registrants use them in good faith. Infringement typically requires evidence of deliberate bad-faith conduct, such as impersonating a specific brand to deceive consumers.
