I just came across a short domain name search application. It’s really easy to use and it produces good results. I found and bought a domain name while using it a minute or so ago.
It’s called NXdom.
From its About page:
NXdom is an interactive search engine for available short domain names. Its database contains millions of DNS results for expired and unused domain names. You can search by prefix and suffix, and sort the results by length, readability, and popularity.
NXdom was created by Johann C. Rocholl in about 2500 lines of Python and powered by Django 1.1 on Google App Engine. The full source code is available at github.com/jcrochol/nxdom under the MIT License.
You can try it out here.
