About

KoalaSync is a free, open-source watch party browser extension for watching videos together online.

Create a room, share an invite link, and keep playback in sync with friends across supported browser video players. KoalaSync synchronizes play, pause, seeking, and episode changes, so you do not have to count down “3, 2, 1, play” over voice chat.

It works with many browser-based video players, including Emby, Jellyfin, Plex, YouTube, Netflix, Disney+, Prime Video and more. No account required, no tracking, and optional self-hosting for people who want to run their own relay server.
