What is CodePen?
CodePen is a social development environment for front-end designers and developers. It’s the best place to build and deploy a website, show off your work, build test cases, and find inspiration.
• Show off the amazing things you build. • Learn new things by tinkering. • Build reduced test cases to report bugs and get help on tricky problems. • Try out new technologies for the first time. • Build components to later use elsewhere. • The possibilities are endless. Everything you do is saved on CodePen, so the more you use it the more useful it becomes.

Said about CodePen as an alternative
Codepen doesn't have as much as repl.it but it is a great alternative for people who love coding websites and such
