The 676 most popular .io domains

I was curious to see the top .io websites, so I searched and found this list, but I wasn't sure the last time it was updated. Below is the list as of 7th March 2014.

I was surprised to see onthe.io break out into the top 3 (it wasn't even on the previous list). That's one spot above the hugely popular soup.io. The online PHP/JS/Mysql application builder is "private and for good people only."

Another newcomer is bitcoin commodity exchange cex.io. From the site:

"CEX.IO is the first commodity exchange, where you can trade mining facilities for a price set by the supply and demand. We believe that mining equipment should be sold for a fair market price."

spring.io jumped way up from 485192 to 9359. "Spring helps development teams everywhere build simple, portable, fast and flexible JVM-based systems and applications."

And flappybird.io moved into the top 10 (wasn't even on the previous list), at number 10. Max McDonnell build his own HTML5 version of the popular game.
