Lavalink
Standalone audio sending node based on Lavaplayer
...This architecture helps larger bots separate audio playback from gateway logic and reduce load on the main bot process. Lavalink provides a REST API for resolving tracks, controlling players, managing playback, and retrieving statistics. It supports seeking, volume control, authentication, Prometheus metrics, Docker images, event handling, and plugin-based extensions. It is widely useful for developers building scalable Discord music bots that need reliable external audio playback infrastructure.
