Hubs lets you bring in content from around the web (or your own computers / phones) to create shared, 3D spaces where you can invite and connect with friends. You may want to invite friends to watch videos on YouTube, live streams on Twitch or look at photos from a past vacation. Hubs provides rooms where you can connect with the people who matter to you, and create custom places together.
For additional information, see the Get started with Hubs by Mozilla article.
