"Finally a watch party that just works. Sent the link to my best friend in another country and we were watching the same K-pop comeback in seconds. No 'press play in 3' nonsense."
"Our squad uses WaveSync for highlight nights instead of screen-share. Quality is 1000x better, chat is right there, and nobody had to download anything. Perfect."
"I have non-tech friends. The fact that they didn't need to make an account is the only reason this actually worked for our movie club. Set up a room in 10 seconds."
Yes. 100% free, forever. No subscription, no premium tier, no ads inside the player.
No. They just open the link and type a display name. No email, no password, no OAuth.
Yes — WaveSync runs in any modern mobile browser. iOS Safari may need one tap to start playback the first time. That's an Apple/YouTube rule, not us.
Yes. Paste a YouTube playlist URL and WaveSync auto-advances through it for the whole room. You can also build a custom queue inside the room.
Rooms are designed for friend-group scale watch parties — small groups and squads. The experience is best when the chat feels personal.
YouTube blocks some videos (private, region-locked, or "embedding disabled") from playing in third-party players. Swap to another video and you're good.
Discord requires every viewer to have a Discord account and be on the same server in the same voice channel. WaveSync needs only a link — great for casual invites with friends not in your Discord.
Only people with your specific room link can join. Rooms are unlisted by default. End the room any time to remove it for everyone. See the Safety Center for more.
