Before we start Codeboxr personally I gave more than one week to find a suitable name that is short and available on all social network as username as well as top level .com domain and certainly match with my idea. I think you are doing the same thing if you thinking for a new startup. Well, here I am trying to list some important website or service that may help you to find if a username or domain name available for the startup name you are thinking.
- http://domai.nr/ This site helps to find domain name of other language
Hope that helps.
Founder & CEO, Codeboxr.
