The Name App
Great little app to find out what potential names for your idea are taken on social networks and popular TLDs (top-level domains). The minimal uncluttered site uses AJAX to retrieve the search results keeping it all in One Page. Thanks for the detailed notes on the build, good job.
This website has unfortunately been redesigned or gone offline, so I have removed the direct link to it. The screenshot below hopefully preserved enough of the design but if you are really keen to inspect further, try this Archive.org link. FYI: the site was first featured on 01 December 2014.
