this checker tries to find domains that fit this format: word: domainname, domain: domainna.me if this is not what youre trying to accomplish either edit the code or use something else.
git clone https://github.com/githubesson/domainchecker
touch wordlist.txt
touch tlds.txt
go run .example tld list: https://raw.githubusercontent.com/danielmiessler/SecLists/refs/heads/master/Discovery/DNS/tlds.txt
wordlist.txt can contain whatever words you want
the .env file contains 1 setting, which is the amount of threads you want to run at once. change as you wish, i havent tested the ratelimits on whois servers so your mileage may vary.
