Video Sync Space — Watch YouTube Together in Sync
Syncs active video player and rooms over encrypted WebSocket with zero account registration
How it works
Video Sync Space (VSS) lets you watch YouTube videos, movies, and live streams together with friends in another city or country without creating accounts on external websites. Open any video, type a room name and optional password (up to 15 characters), and copy the direct invite link so friends can join in one click without typing the password. Play, pause, and seek stay aligned in real time alongside an in-page chat window, while Ad Shield re-syncs everyone automatically after ad breaks.

How do I invite a friend without sending the room password separately?
Open a YouTube video, click the VSS icon, enter a room name (plus an optional password up to 15 characters), click Connect, and hit "Share Invite Link" to copy a direct 1-click join URL.
What happens when YouTube plays an ad for one person in the room?
Ad Shield detects ad playback and automatically re-aligns everyone’s video timeline as soon as the ad break finishes.
