Hyperbeam free is great until the 3-hour cap and 10-minute wait kick in. SyncUp has no session limits and supports YouTube, Twitch, and Kick natively.

Hyperbeam shares one virtual browser session for everyone in the room, which is clever but expensive to run. The free tier caps sessions at 3 hours and adds a 10-minute wait between rooms. SyncUp syncs each viewer's own playback for free, with no session limits, and supports YouTube, Twitch, and Kick natively without needing a shared browser.
No, and that's intentional. Hyperbeam streams one browser to everyone, so quality depends on the host's session. SyncUp keeps playback local on each device and only synchronizes the timestamp, so each viewer gets full quality on their own connection.
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.
SyncUp focuses on supported sites (YouTube, Twitch, Kick, HTML5 video, plus Netflix and Disney+ via the free extension) instead of arbitrary browser sharing. For most watch parties, that covers what people actually want to watch.
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, or Edge.
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.
