TUpeerTube is currently in a beta stage.
TUpeerTube is a video platform of TU Wien based on the open source product PeerTube. On this platform employees of TU Wien can upload self-made (learning) videos and make them available. It works similarly to commercial services like YouTube, DailyMotion etc. The videos are hosted on a server of TU Wien.
