Host free Prime Video watch parties for The Boys, Reacher, and everything on Amazon Prime. 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 Prime Video, our free browser extension enables synchronized playback. Each person needs their own Prime Video subscription.
Prime Video used to have a built-in Watch Party, launched back in 2020. Amazon discontinued it on April 2, 2024. Last verified: May 2026. As of now there is no native Prime Video watch-party option, so syncing a show with friends means using a separate tool that lines everyone up.
SyncUp is one way to do that. It mirrors play, pause, and seek across the room within about 200ms over a WebSocket connection. The video itself still streams from Amazon at your own quality, since SyncUp syncs timing only and does not re-stream or compress anything. If you are weighing options, the watch party apps comparison goes through the current alternatives.

SyncUp makes watching Prime Video 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 Amazon Prime Video subscription.
Yes. SyncUp and the browser extension are free. Free rooms hold up to 5 viewers, and the optional Plus plan ($3.99/month) lifts the cap to 50 for everyone in the room. You'll still need a Prime Video subscription for the content itself.
No. Amazon discontinued its built-in Prime Video Watch Party on April 2, 2024, so there is no longer a native way to sync Prime Video with friends. SyncUp fills that gap with its free browser extension, and the same room can also watch Netflix, Disney+, YouTube, Twitch, and more. Last verified: May 2026.
Yes. Prime Video 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.
Prime Video 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 the same title. SyncUp only syncs playback events. Each viewer streams the title from their own Amazon account, whether it's included with Prime, rented, or purchased.
Install the free extension and you can start a Prime Video watch party in a few minutes.
