Startup Validator

I like it, it solves a common problem. It would help if you can check the availability of other domain extensions, ".me .io .co ...etc". Also a small idea: I think hitting enter while the focus is inside the input should trigger the search action.

Cool tool! simple but practical, good luck!

That's a nice tool, It would be really useful with support for more social platforms (e.g Instagram or YouTube)

It would be great if the result would load faster and would contain a wider search. Good alternatives are Namecheckr (https://www.namecheckr.com) and Namecheck (https://namechk.com). I used both in the recent past a lot and they are very helpful.

Also http://knowem.com - which searches over 500 social networks and domains :)

Kinda pointless when it doesn't factor in that twitter usernames can only be 15 chars long.

Simple and super useful. Nice one!
