PeerTube is an open-source video hosting platform that allows users to create and share videos without relying on centralized services like YouTube. It operates on a decentralized network, meaning that anyone can host their own instance of PeerTube, contributing to a diverse ecosystem of video content. Users can upload videos, follow channels, and interact with other viewers, similar to traditional video platforms. However, PeerTube emphasizes user control and privacy, as it does not track users or serve ads. This makes it an appealing alternative for those seeking a more community-driven approach to video sharing.
