A free extension for Chrome by Joker Development
For days where you can’t hang out with friends or family and can’t bond over various YouTube videos from your favorite channel, we have a Chrome extension for you!
GroupTube is a Chrome web browser extension that lets you watch YouTube videos with a group of friends. With this add-on, the video will be completely in sync among all viewers. The video can be controlled by you or one of your friends. When you take control, you can play, pause, and skip to a specific timestamp which will then be updated for everyone else who is watching it. For a better and uninterrupted viewing experience, this extension works best with an ad blocker.
