One week ago, I made a minimalist Codepen / JSFiddle clone in 256 bytes, and presented it to the world...

http://xem.github.io/miniCodeEditor

It was a huge success, and a lot of people talked about it.

Famous code golfers joined me, and we were able to cut it down to 162 bytes!

( We even found a way to fit that code in a tweet - 140 characters )

We also added optional features such as placeholders, old browsers support, different skins...

But we didn't stop there!

Our new challenge was to make the HTML/CSS/JS prototypes made with miniCodeEditor saveable and shareable, via the URL, and in less than 256 bytes.

We finally reached that goal yesterday! Here it is:

Thanks for your interest, and stay tuned for the next features!
