CodePen is a social development environment. At its heart, it
allows you to write code in the browser, and see the results
of it as you build. A useful and liberating online code editor
for developers of any skill, and particularly empowering for
people learning to code. We focus primarily on front-end
languages like HTML, CSS, JavaScript, and preprocessing
syntaxes that turn into those things.
- Steve Jobs
CEO
We say social, because CodePen is a community. Most creations
on CodePen are public and open source. They are living things
that other people and the community can interact with, from a
simple hearting, to leaving a comment, to forking and changing
for their own needs.

People use CodePen for all sorts of things: prototyping new
ideas, reduced test cases for bugs, sending clients things to
look at, evaluating potential hires, to finding inspiration.
People also use CodePen as a sort of resume and portfolio,
showing off their best design and development work.
