Jsfiddle-like embeds?

It is great to have codepen, but our community prefers jsfiddle as most of the examples and issues are tested there. jsfiddle does have embed code, and this is what http://jsfiddle.net/hw9rcLL8/ looks like in iframely.

Here is what the embed code looks like:
<iframe width="100%" height="300" src="//jsfiddle.net/hw9rcLL8/embedded/" allowfullscreen="allowfullscreen" frameborder="0"></iframe>

What would be the way forward to support this on our discourse?
