⚙️ How It Works
Input:
You start by entering a domain name (Or a label, which is the first part
of the domain).
Functionality:
the script will check hundreds of other TLDs for status or availability
Output
the results are ordered as follows
- First result will be your domain (If you have entered a domain name rather than a label)
- The following results will be domains that are currently registered and not available for registration
- And last but not least, the domains that are available for registration
Extra data about domains that might display includes data that will tell you if a domain is worth monitoring for availability
- Domain is in registry redemption
- Domain is for sale by its owner
- Domain pending delete
- Domain inactive
No more guessing, no more checking one by one. Let us do the hard work.
