I've searched for domain names quite often and enjoyed it a lot. I wrote a small nodejs program for domain hunting for some time. Decided to put it into a desktop app and push it this weekend.
This Domain Tool can help you:
Why a desktop app? For a few reasons, (1) I concern about privacy when searching for domains (might not be necessary, but I keep thinking about it). (2) I used some name suggestion web app and someday, they just went offline or disappear.
The Domain Tools is available (for MacOS and Windows) on https://ish.im
