Plumi
Plumi is a free software video-sharing content management system developed based on the open-source content management system Plone. Plumi allows users to create a video-sharing website by adding it to an existing Plone instance. The software includes various functions to facilitate video distribution and community creation. Plumi aims to help establish "community-controlled, non-commercial, free, and open source alternatives" to popular alternatives such as YouTube. It was designed to allow communities and "citizen publishers to create video-sharing communities out of the box." It was also said that the free software was designed to be more accessible to non-profit groups and independent journalists. History
