Host free Paramount+ watch parties for Star Trek, Yellowstone spin-offs, and everything on Paramount Plus. The SyncUp browser extension keeps everyone in sync within about 200ms.
Free for Chrome, Firefox, and Edge
SyncUp natively supports YouTube, Twitch, Kick, and thousands of HTML5 video sites - no extension needed. For streaming services like Paramount+, our free browser extension enables synchronized playback. Each person needs their own Paramount+ subscription.
Paramount+ does not include a built-in feature for watching in sync with friends. Last verified: May 2026. That puts it in the same spot as most major services now that Amazon Prime (April 2024) and Disney+ (September 2023) retired their own group-watch tools. Hulu's ad-free tier is one of the few exceptions left, and Paramount+ never had one to begin with.
So if you want to watch a Star Trek premiere or a Sunday match together, you need something on top of the app. That is where the free SyncUp extension comes in.
Paramount+ streams are DRM-protected, so SyncUp does not touch the video. The extension watches for play, pause, and seek on your tab and passes those events to everyone in the room over WebSocket, typically within about 200ms. The picture still comes straight from Paramount+ at your own quality, and each person signs in with their own account. For a quick start, create a room on SyncUp, share the code, and load the same title. Live broadcasts already play in real time, so for sports the sync mostly keeps your pauses and reactions lined up.

SyncUp makes watching Paramount+ together straightforward and free. Here's how it works:
Play, pause, and seek actions sync within 200ms via WebSocket. Occasional drift can happen on longer sessions, but a quick resync fixes it.
Invite as many people as you want. We've tested rooms with 50+ viewers without issues.
SyncUp syncs playback timing only - video streams directly from the source at whatever quality you choose.
Install the extension once (takes about a minute), then create watch parties with a couple clicks.
Install the free SyncUp browser extension, create a watch party room, and share the room code with your friends. Everyone with the extension installed stays in sync within about 200ms. Each viewer needs their own Paramount+ subscription.
Yes. SyncUp and the browser extension are free. Free rooms hold up to 5 people, and the optional Plus plan ($3.99/month) lifts the cap to 50 for everyone in the room. You'll still need your own Paramount+ subscription for the content.
Yes. Paramount+ uses DRM-protected playback, so the SyncUp extension is required to sync video events. The extension is free and installs in under a minute on Chrome, Firefox, or Edge.
Paramount+ watch parties require a desktop browser because mobile browsers don't support extensions. SyncUp works on mobile for YouTube, Twitch, and Kick without an extension.
Yes. As long as each viewer has access to a title in their own Paramount+ plan (including the Showtime bundle), SyncUp will sync playback. SyncUp doesn't bypass DRM and doesn't share streams.
Paramount+ live content (including soccer broadcasts) is DRM-protected and works with the extension. Live streams already play in real time, so sync mostly matters for pauses and reactions during the broadcast.
Install the free extension and you can start a Paramount+ watch party in a few minutes.
