PeerTube is a free, decentralized, and federated video platform that allows users to upload, share, and stream videos without vendor lock-in or ads. The platform uses P2P technology to share the load among users and instances can help each other by caching one another's videos. PeerTube is developed as an alternative to centralized video platforms like YouTube and Vimeo. It is community-owned and allows content creators to receive support directly from their viewers.
