I don't like it. I still prefer Codepen and jsfiddle.

Yeah, I don't see this as an attempt to be another Codepen or jsfiddle. This is just a way to easily test out features of a language, without going through the (sometimes very tedious) installation and setup processes required to code in certain languages locally.

What do they do for languages other than JavaScript?

Ok, then Codeanywhere would be a better choice. Don't you think? ;)

Saying that Codeanywhere is a better choice than TIO is like saying that GMail is a better choice than Netflix.

In both cases, both services were built for different purposes, and neither one can or intends to replace the other.
