  • Bulk stop/pause/continue mechanism

  • Proxy integration

Be aware that

Its your sole responsibility what you do with this tool, its intended to let anyone have a chance at finding a good domain in a crowded space. Is also known that repeated whois requests to a server will eventually result in IP blacklisting, you should have a conservative value for time between requests and bit of common sense to minimize the risk of blocks, don't do huge bulk lookups at once or with the same ip, preferably use different proxies between requests.

Quick Start

To stay on the bleeding edge of whoisdigger updates do git clone or for more stability download the latest release.

Using wordlists

Wordlist files should have one word per line without TLDs suffixes, spaces or special characters if intended, they should also be in UTF-8 encoded and follow the example below:

wordlist.txt (Text file)


Wordlists by manual input should follow the same rules with the only difference of being pasted at input stage.

Sample wordlists

Whoisdigger provides sample wordlists as example for testing purposes inside sample_lists folder.

Exporting bulk processing results

At export stage the user is given several options, you can decide what domain status to export, if you want domains that threw errors included, their basic information if not available such as creation, expiry and update dates. Exporting as text file will only export invidualized whois replies for each domain in a zip file, as a csv you're able export both basic information and whois replies in text, inline csv or separate csv files in a zip for organization.

Notes on errors

Errors when doing bulk lookups are common due to the nature of bulk requests, this means that requests will get blocked, throttled or delayed resulting in errors. Errors commonly refer to already registered domains so most times you can assume that they're already taken. Uniregistry has a very low threshold on whois requests resulting in temporary block as soon as 3 rapid requests hit their server, in this case you can also assume its taken.


Whoisdigger uses electron-packager for builds.
