CodePen is an online community for testing and showcasing user-created HTML, CSS and JavaScript code snippets. It functions as an online code editor and open-source learning environment, where developers can create code snippets, called "pens," and test them. It was founded in 2012 by full-stack developers Alex Vazquez and Tim Sabat and front-end designer Chris Coyier.[1][2][non-primary source needed] Its employees work remotely, rarely all meeting together in person. CodePen is a large community for web designers and developers to showcase their coding skills,[3] with an estimated[by whom?] 330,000[4][unreliable source?] registered users and 14.16 million monthly visitors.[5][unreliable source?]
