I wasn't even in the market for this, but I'm sure glad it crossed my path because it's pretty great! As a user of CodePen, I was completely satisfied with what they have to offer, but I was shocked to learn that I actually like this better. It's fast, has a great UI and the dev seems to have thought of everything. If I am in need of something or want to customize to my liking, I just poke around and boom, there it is! This speeds up my testing/development and I appreciate that. The only thing I don't like is having to log in to my email to retrieve a code in order to log in to PlayCode. It's frustrating every time.

Having said that, if you're on the fence, you should at least check it out. If you don't like it, you know what to do.
