Peertube is a de-centralised alternative to YouTube as a method of sharing videos. Content comes from a wide range of creators.
For individuals – explore some of the content – share links with items you have enjoyed with friends. If you create video content, which you want to share, find a site which will host it for you.
For small to medium sized organisations – investigate running your own peertube instance – via hosting provider.
Examples
