PeerTube is the Fediverse's alternative to YouTube, and lets anyone start their own independent video server. It uses p2p technology to allow even small servers to host viral videos.

You can follow the project at @peertube and the website is at https://joinpeertube.org

Because it's part of the Fediverse, you can follow PeerTube accounts from Mastodon etc. For example, try following @chriswere. Followers will see the account's videos appear in their timelines, and if they reply to a video post it will appear as a comment below that video in PeerTube.

Android apps for PeerTube include FediLab and TubeLab (https://fedilab.app), but you can use it directly through the browser on any platform.

If you want to start your own PeerTube server, there are lots of options:

-Easiest by far is to use a managed hosting service (see https://growyourown.services/grow-your-own-social-network/)

-Next easiest is to use @yunohost (see https://yunohost.org)

-Most difficult is installing manually (see https://docs.joinpeertube.org)
