KoalaSync
Free & private universal watch parties on any website - no accounts, no tracking, no ads.
About KoalaSync
KoalaSync is a lightweight browser extension that keeps you and your friends perfectly in sync on YouTube, Netflix, Twitch, Prime Video, Jellyfin, Emby, and almost any other site with an HTML5 video player — press play once and everyone stays together. It's built privacy-first: no accounts, no telemetry, and the official relay server runs entirely in volatile RAM with zero persistence, so nothing about your sessions is ever stored. Open source under the MIT license and fully self-hostable with a single Docker Compose command, KoalaSync is a transparent watch-party tool that works everywhere and respects your data sovereignty.
