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. 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, with an estimated 330,000 registered users and 14.16 million monthly visitors.

## How to interpret this page

Estimated down reports are based on US Google Trends problem-intent searches. Values are relative activity from 0 to 100, not counts of submitted reports. The HTML chart averages samples into ten-minute intervals. Partial samples are excluded and missing samples are not invented.

Recorded outage reports and estimated activity are separate signals. Neither confirms that every user is affected. Missing or stale data does not establish that a service is working.
