Finding a usable domain can be the most difficult part of starting a new project. Most of the obvious domains are taken, or worse reserved and sold at exorbitant prices, so you'll have to get a little creative.
Lean Domain Search helps you find great available domain names by pairing your search term with thousands of other keywords commonly found in domain names and instantly showing you which are still available to register.
Instant Domain Search Engine is an Ajax based domain search application using Shell Script Dig Command to check domain availability. There are many benefits of using shell script rather than PHP functions or 3rd party API, such as faster response.
