MediaCMS is a modern, fully featured open source video and media CMS. It is developed to meet the needs of modern web platforms for viewing and sharing media. It can be used to build a small to medium video and media portal within minutes.
It is built mostly using the modern stack Django + React and includes a REST API.
Designed for personal use only. If you want people to be able to create accounts, you can do that. If you want it to be "everybody but me can only watch thigns," you can do that. If you want the entire install to be private and requiring logins from everybody, you can do that, too.
