Domain hack generator: words that end in a domain extension, checked for availability
In short: Enter words or a brand name and see every way the word's ending can be a domain extension (market.ing, brew.ing, delicio.us), each checked against its registry: likely available, registered or unknown. Limit: Only suffix hacks: the dot goes before an extension at the end of the word, never inside a subdomain.
A domain hack is a domain where the extension finishes the word, such as delicio.us or market.ing. Enter up to 25 words and this generator finds every split where the ending is a real extension open to the public, from about 240 country codes and 90 generic ones, then checks each against its registry's RDAP server and DNS.
Price: this tool is free. Checking a whole email list is from $9/mo, and the first 100 checks are free with Google, no card. See pricing

How do I find a domain hack for a word?
- Enter words or names, one per line, up to 25. Spaces are joined, so northwind studio becomes northwindstudio.
- Press Find domain hacks. Every ending that is an extension open to the public becomes a candidate, with at least two characters before the dot: marketing gives market.ing and marketi.ng.
- Each candidate is checked against its registry's RDAP server and DNS: likely available, registered or unknown.
- Copy the likely available ones or download the CSV, then check the registry's eligibility rules and the price at a registrar.

What is a domain hack?
A domain hack is a domain name whose extension is part of the word or phrase it spells: del.icio.us, goo.gl and bit.ly are well-known ones. Most use two-letter country codes, because so many words end in pairs of letters that are also country codes (.us for the United States, .ly for Libya, .in for India, .es for Spain).
This generator only builds hacks where the dot comes before the extension, so the result is a name you register, not a subdomain. It needs at least two characters before the dot.
Which extensions does it use?
The two-letter country codes in the ICANN section of the Public Suffix List, leaving out the few that take no public registrations (.bv, .sj, .gb, .kp, .er, .va, .aq), plus about 90 generic extensions open to anyone, such as .ing, .ink, .app, .art and .tech. Brand extensions (.google) and restricted ones (.law, .bank) are left out, because their registries answer "no record" for names nobody outside can register.
Why do so many hacks show unknown?
Because many country-code registries publish no RDAP service, including .io, .co, .me, .us, .it, .es and .de. There's no standard way to ask them, so a hack there is shown as registered when DNS proves it, and unknown otherwise. Check those at a registrar that sells the extension.
Country codes also set their own rules. Some only register to residents or local companies (.us, .ca, .eu, .it for EU residents), and a few charge far more than a .com. The registry's website lists both.
Are domain hacks good for email or a business?
They're memorable and short, which suits link shorteners and side projects. For a main business domain they have two costs: people mistype them as .com, and an unfamiliar country code can look odd in a sender address. If you send email from one, set up SPF, DKIM and DMARC like any other domain and warm it up slowly.

What can’t this tool tell you?

Common questions
- How do I make a domain hack?
- Find an extension that matches the end of your word and put the dot before it: marketing becomes market.ing, delicious becomes delicio.us. This generator tries every open extension against every word you enter.
- Is the domain hack generator free?
- Yes. Up to 100 hacks are checked a run with no account and up to 500 after a free Google sign-in, with no card.
- What are some famous domain hacks?
- del.icio.us, bit.ly, goo.gl, youtu.be and redd.it. Most use a country code, which is why the extension's own rules matter.
- Why didn't my word give any hacks?
- Its ending isn't an extension open to the public, or the word is too short to leave two characters before the dot. Words ending in -ing, -ly, -us, -in, -io, -es and -er usually work.
- Does likely available mean I can register the hack?
- Usually, not always. Premium and reserved names can look free, and some country codes only register to residents. The registrar's checkout is the final word.

The other half is who you send to. Every hard bounce counts against the domain and inboxes you are sending from, and nothing in DNS can tell you which addresses on your list are dead.
