Why Choose SyncUp Over Synctube?
Synctube has been around for years and pioneered free YouTube watch parties. SyncUp picks up where it left off: more sources, modern UI, playlist voting, and active development.
More Sources, Not Just YouTube
Synctube is YouTube-focused. SyncUp adds Twitch, Kick, SoundCloud, YouTube Music, HTML5 video, and streaming services via free extension.
Modern Interface
Clean dark UI, mobile-first layout, and features that look like 2026, not 2014.
Playlist Voting
Let the room vote on what to watch next. Built-in queue management with role-based controls.
Real Mobile Support
Watch parties on your phone or tablet, not just desktop. No app download needed.
Free To Use
The basics stay free. Optional Plus plan if you want bigger rooms or longer voice chat.
Privacy First
Private rooms by default. Only people with your code can join.
Want Streaming Service Support?
Install the free SyncUp extension to watch Netflix, Disney+, HBO Max, Amazon Prime Video, and other DRM-protected streaming services together. Works on Chrome, Firefox, Edge, Opera, and Brave.
Synctube Alternative FAQ
SyncUp is built by one developer. Anything missing here, just ask.
Contact the developerWhy use SyncUp instead of Synctube?
Synctube is YouTube-only and hasn't seen meaningful updates in years. SyncUp supports YouTube, Twitch, Kick, SoundCloud, YouTube Music, and HTML5 video sites natively, adds streaming services like Netflix and Disney+ via a free browser extension, and is actively maintained. The basics are free with no signup.
Is SyncUp really free?
Yes. The basics are free: rooms, sync, chat, playlist voting, friends, and watching YouTube, Twitch, Kick, SoundCloud, and YouTube Music. Free rooms hold up to 5 people. There's an optional Plus plan if you want bigger rooms or longer voice chat, but you don't need it.
Does SyncUp work for YouTube the same as Synctube?
Yes, with extras. SyncUp syncs YouTube playback the same way (play, pause, seek), supports playlists and search, and adds playlist voting so the room can pick what's next. You can read the full guide on our watch YouTube together page.
Do I need to download anything?
No. SyncUp works in any modern browser on desktop or mobile. For Netflix, Disney+, and other DRM-protected streaming services, install the free SyncUp browser extension for Chrome, Firefox, Edge, Opera, or Brave.
Does SyncUp work on mobile?
Yes. SyncUp is built mobile-first for YouTube, Twitch, Kick, SoundCloud, and YouTube Music. No app download required. Streaming service support via the extension is desktop-only because mobile browsers don't support extensions.
How many people can join a watch party?
Free rooms hold up to 5 people. If anyone in the room has Plus, the cap goes up to 50 for everyone in that room, so one Plus user can host a bigger group without the rest needing to subscribe.
