I recently stumbled across AJAX Whois, which may have become my new favorite way to find domains and check WhoIs info. It’s fast, and it’s easy to use.

I’m serious when I say AJAX Whois is fast. Start typing in the form, and the web app searches as you type. By the time you’ve finished typing in a domain, the results are already there.

There are a couple of small features that really make the site easier to use. Number one is the favorites feature. If you find a domain that you want to remember while you’re searching other ones, you can just click the favorite button and it will be added to a space in the sidebar for easy access. The other feature is even simpler, yet you would really miss it if it wasn’t there; You don’t have to enter a TLD when searching. Many whois services require that you enter a TLD, even if you want to see results for multiple TLDs. Luckily AJAX Whois doesn’t follow that trend.

Looking for a domain? It sure can get frustrating when you enter 375 different ideas into a WhoIs service, only to find that they’re all registered.

While Tabeze can’t help you come-up with more ideas, it can help you check their availability easier.

Tabeze is a domain availability checker that allows you to, with the press of a key, open as many search boxes as you want. Type a domain (including the TLD) into a box and press enter, and Tabeze does the rest. You can open more search boxes so you can check more domains at once, or you can do it so you can leave positive results onscreen for later reference. There are many ways to use this innovative feature.

My biggest complaint is that, unlike normal WhoIs services, it doesn’t show alternate TLDs that are available. If I search superwebmegasite.com on WhoIs.net, it will let me know if it’s available, and mention whether superwebmegasite.net and superwebmegasite.us are available. Tabeze doesn’t do that.
