<strong>But PeerTube doesn't centralize: it federates.</strong> Thanks to the <a target="_blank" rel="noopener noreferrer" href="https://activitypub.rocks">ActivityPub</a> protocol (also used by <a target="_blank" rel="noopener noreferrer" href="https://joinmastodon.org">the Mastodon federation</a>, a free/libre Twitter alternative), PeerTube can federate several small hosters so they don't have to buy thousands of hard disks to host videos for the whole world.
<strong>It's software you install on your server</strong> to create a website where videos are hosted and broadcast... Basically: you create your own "homemade YouTube"!
