For the last few years I've been toying with a variety of techniques for finding available domain names. This is one of my more recent attempts that I thought would be useful to all of you on HN. I created a simple search and alphabetical lookup with pagination to be able to browse through these domains as easily as possible. I built the website search functionality yesterday, so it was quick and dirty (but hopefully the UI is clean enough).
Since the current listing is cached, the only way to tell if a domain is truly still available (and some other HN member hasn't picked it up), you need to click the "Test" button to run a new WHOIS test. If the domain is taken, it'll automatically be removed and you'll be informed. If not, you'll get a nice little success message with both purchase buttons.
I'd love any suggestions. Let us know if you find anything good :)
