Domain Typo Generator
Generate the typo variants of a name or domain, such as skipped, doubled and swapped letters, and see which are free to register.
How the Domain Typo Generator works
Type a keyword or a domain and tick the kinds of typo to generate: skipped key, doubled key, reversed key (two neighbours swapped), missed key, inserted key and bit flip. Skipped, doubled and reversed typos work on the letters themselves. Missed key replaces a letter with a key next to it, and inserted key adds a neighbouring key before or after it. Keyboard-miss variants use a QWERTY layout. A bit flip changes one bit in a letter code and keeps the result when it is another lower-case letter.
With a keyword, each typo gets .com. With a domain such as handreg.co.uk, typos of the name are combined with .com, your extension and typos of the extension that are real extensions. Your browser checks each result with DNS lookups against Cloudflare and Google. Nothing you type is sent to Handreg.
Worked example
Keyword cat with Skipped key, Doubled key and Reversed key ticked. Skipping each letter gives At, Ct and Ca, doubling each gives Ccat, Caat and Catt, and swapping neighbours gives Act and Cta. Each gets .com:
Input cat
At.comCt.comCa.comCcat.comCaat.comCatt.comAct.comCta.com
The results are in that fixed order, and duplicates are not removed, so a letter that is doubled twice appears twice.
How to use it, step by step
- Type a keyword such as handreg, or a domain such as handreg.com.
- Tick at least one typo type.
- Press Generate. The typos appear at once and their statuses fill in.
- Sort by typo, length, domain or status, copy a column, or export the whole list as CSV.
- Look for Likely Available rows and confirm them at a registrar before you register.
How to read the results
Typo is the misspelled name, Length its length and Domain the full name that was checked.
A typo that is Taken may already belong to someone else, perhaps a competitor or a parked page, and the Archive link can show what was there. A Likely Available one is a candidate to register if you want to catch those visitors.
Taken means Cloudflare or Google DNS reports that the name already exists. Likely Available means neither found it, or the check could not finish. A name can be registered without being in use, so a Likely Available name can still be taken: confirm it at a registrar before you buy. Names with fewer than two characters, and .com names of four or fewer letters, are shown as Taken without a lookup.
Frequently asked questions
What is typosquatting?
Typosquatting is registering a misspelling of a well-known domain to catch visitors who mistype it. The owner may show ads, redirect traffic or, in the worst cases, imitate the real site. Registering the likeliest typos of your own domain is one way brands protect themselves.
Which typos should I register to protect a brand?
There is no fixed rule. A common approach is to start with the typos people are most likely to make, such as a skipped or doubled letter, swapped neighbours and a missing letter in the extension like .cm for .com, then weigh the yearly cost against the traffic you could lose. Monitoring the taken ones can also be enough.
What is a bit flip domain?
A bit flip domain differs from a real one by a single flipped bit in the binary code of one letter, which can turn a request for one name into a request for another when memory or a connection makes an error. The tool flips each of the eight bits of every letter and keeps the results that are lower-case letters.
Which keyboard layout does the missed key and inserted key option use?
A QWERTY layout. For each letter or digit the tool uses the keys next to it on a QWERTY keyboard, so a typist on another layout such as AZERTY or QWERTZ may make different slips that this tool does not generate.
Can I enter a full domain instead of a keyword?
Yes. With handreg.co.uk, the tool makes typos of handreg and pairs each with .com, with .co.uk and with typos of the extension that are real extensions in its list. The dots are only allowed here, not in the other tools.
Why do some results look the same?
Duplicates are not removed. Doubling a letter that is already doubled, or skipping one of two equal letters, gives the same word more than once. They are harmless and you can sort by typo to see them together.
