Bulk Domain Hack Search
Paste a list of words and get the domain hacks for all of them in one table, each checked for availability, ready to export as CSV.
How the Bulk Domain Hack Search works
Each word you paste goes through the same domain hack logic as the single Domain Hack Generator: if the word ends with one of 363 extensions, the tool splits it there and puts in the dot. All the hacks from all the words are collected in one table, in the order of your list.
Your browser then checks every result with DNS lookups against Cloudflare and Google, in batches of 500 results (900 once a list produces more than 5,000). Large lists take longer, and the time depends on your connection. Your words are not sent to Handreg.
Worked example
Paste these three words, one per line or separated by commas: internet, delicious, bakery. The tool returns three hacks. internet gives two, delicious gives one and bakery gives none, because it does not end with an extension in the list:
Input internet, delicious, bakery
Intern.etInter.netDelicio.us
In the table the domains are shown with a capital first letter. The availability check uses the lower-case form, which resolves the same way in DNS.
How to use it, step by step
- Type or paste your words, one per line or separated by commas. Spaces are ignored.
- Press Generate. Entries with unsupported characters are skipped, and the tool tells you how many.
- Watch the statuses fill in while the batches are checked, then use the page buttons to move through 20 results at a time.
- Sort the whole table by domain, length or status, or copy a column.
- Press Export To CSV to save the complete list as handreg.io.csv.
How to read the results
Each row is one hack of one of your words. Words that produce several hacks appear several times, once per extension, and words that produce none do not appear.
Status works as in the single tool: 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. Checking means the lookup is still running.
The CSV holds every row, not only the page you are looking at: the hack, its length, its status and the research links. Cells that a spreadsheet could read as a formula are prefixed with an apostrophe so they stay text.
Frequently asked questions
How do I check many domain names at once?
Paste your words into the box, separated by commas or new lines, and press Generate. The tool builds the domain hacks for every word and checks all of them together. It works from words, not from finished domain names, so for a plain list such as example.com a registrar bulk search is a better fit.
How many words can I paste?
There is no fixed limit. Lookups run in batches of 500 results, or 900 when a list produces more than 5,000, and each result needs two DNS lookups. A very long list therefore takes a while and depends on your connection, so start with a few hundred words.
Can I enter words without an extension?
Yes, that is how it works. Enter the plain word, for example internet, and the tool finds the extensions that complete it. If you type a full domain with a dot, it is rejected because only letters, digits and hyphens are accepted.
Why do some of my words return no results?
A word only produces a hack when its ending matches an extension in the list. Bakery ends with ery, which is not an extension. Matching is case sensitive against lower-case extensions, so type your words in lower case or with a leading capital letter, not all in capitals.
What does the CSV export contain?
The file handreg.io.csv contains one line per result with the domain, its length, its status and the registrar and research links. Values with commas or quotes are quoted correctly, and cells that start with an equals sign, plus, minus or at sign get a leading apostrophe so a spreadsheet does not run them as formulas.
Are my words sent to a server?
Not to Handreg. The generating happens in your browser. The only network requests are the DNS lookups for each result, which go from your browser to Cloudflare and Google, so those two services can see the domain names you check.
