How it works
The editor includes live preview, preprocessors such as SCSS and TypeScript, and a huge library of shared work you can fork and modify. A Pro plan adds private pens, asset hosting, collaboration mode, and professor mode for teaching, which makes it useful for teams and educators as well as individuals.
CodePen is the standard playground for front-end code, and it is free for most uses. It is not a replacement for a full IDE or a deployment platform, but for prototyping, learning, and sharing front-end ideas, it is one of the best tools available. Start free and upgrade only if you need private pens or collaboration.
