See the results of your code on multiple computers or devices as-you-type. Great for mobile testing or if you prefer having a full-page preview to watch as you work.
If those other devices can receive text messages, you can send over the live URL directly from the editor just by entering the phone number. Works anywhere in the world!
Need to use an image in a Pen? No more awkwardly finding alternate hosting for it, you can drag-and-drop it right onto CodePen and we'll host it for you.
Live collaboration on code. Multiple people can type and edit code in a Pen at the same time, all while still seeing the live preview. There is a chat area too, all for the best in long distance pair programming!
Have students watch you work in real time! Every key press and click is shown live. Better than video - the students can interact with the code, see it live rendering, and participate in group chat.
Students can even pause and play around with the code, and then catch back up to you with a single click.
Mark your in-progress work as Private, so nobody can see your Pens until you want them to. Or, use a secret shareable URL to share it only with people you choose.
Private pens are unlicenced, so you may apply your own before sharing so that you retain full ownership.
It’s just $9/month or $75/year.
