PeerTube

A Fediverse video sharing and livestreaming, platform, sort of like YouTube but federated onto lots of independent servers. Because it’s part of the Fediverse, you can follow PeerTube accounts from Mastodon etc and the new videos will appear in your timeline just like normal posts. You can also interact with them within your timeline, for example replies to a PeerTube video within Mastodon will turn into comments under that same video on PeerTube.
