Synctube works for YouTube, but that's about it. SyncUp adds Twitch, Kick, streaming services, playlist voting, and a modern mobile-first interface. Still free, still no signup.
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.
Synctube is YouTube-focused. SyncUp adds Twitch, Kick, HTML5 video, and streaming services via free extension.
Clean dark UI, mobile-first layout, and features that look like 2026, not 2014.
Let the room vote on what to watch next. Built-in queue management with role-based controls.
Watch parties on your phone or tablet, not just desktop. No app download needed.
The basics stay free. Optional Plus plan if you want bigger rooms or longer voice chat.
Private rooms by default. Only people with your code can join.
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, and Edge.

Synctube is YouTube-only and hasn't seen meaningful updates in years. SyncUp supports YouTube, Twitch, Kick, 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.
Yes. The basics are free: rooms, sync, chat, playlist voting, friends, and watching YouTube, Twitch, and Kick. 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.
