Codepen provides an interactive playground with support for most of the commonly-used languages. Not only is it pretty easy to use but also a very powerful tool for anyone from a beginner to a pro developer. Review collected by and hosted on G2.com.

If the code is quite heavy, the webpage becomes less responsive and laggy which is a problem faced by most of the playgrounds. Also, the window which shows the output is pretty small and its a bit of hassle to change its dimensions. Review collected by and hosted on G2.com.

Along with the option to share your Pen on reknowned platforms like GitHub, they also have a very vast & supportive community of their own where you can share your work & also like, review and even collaborate on pen shared by other users of the community. When I was in my learning phase of Web development, CodePen has helped me a lot! Watching tutorials is of no use if you don't get your hands dirty & try out the things, you've learned, on your own. CodePen is just the right platform to help you implement your skills & get real experience! Review collected by and hosted on G2.com.

I don't particularly hate anything about CodePen but if there was support for some backend as well, it would have been great! Review collected by and hosted on G2.com.

It suits the need to provide example or starting point of code to others as well as ask questions or ideas or improvement to the piece of code done.
