Owncast

Owncast is a self-hosted live streaming server that provides full control over broadcast infrastructure and audience data. It functions as an RTMP video streaming server, accepting incoming video feeds and distributing them to viewers through HLS-based segmented streaming. The platform includes a built-in, stateful web-based chat interface that enables real-time viewer engagement during broadcasts.

The project distinguishes itself through deep integration with the decentralized Fediverse, allowing servers to automatically broadcast stream status updates and notify followers across distributed social networks. It is designed for extensibility and performance, supporting event-driven webhooks for automation and offloading resource-intensive tasks like video encoding and media storage to external hardware or cloud-based object storage providers.

The platform offers a comprehensive suite of tools for managing live content, including adaptive bitrate streaming, moderator controls, and customizable public interfaces. Administrators can tailor the viewer experience through theme variables, custom client scripts, and embedded components that allow video and chat to be integrated into external websites. The system also provides robust observability, with support for exporting performance metrics and monitoring hardware utilization to ensure stable stream delivery.
