PeerTube is a free software video hosting platform which can be used to setup a website similar to YouTube and BitChute. It is sort-of peer to peer software, one PeerTube instance can subscribe to and share videos from another PeerTube instance. The software is written for NodeJS. It can easily be setup on a server as long as it is fairly powerful (for video transcoding) and it has a high-bandwidth link.
