Host free Netflix watch parties with friends anywhere in the world. 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 Netflix, our free browser extension enables synchronized playback. Each person needs their own Netflix subscription.
Netflix has never shipped its own watch-together feature, so people reach for a third-party tool. The common one is Teleparty (formerly Netflix Party), a browser extension that syncs Netflix and chats over text. For a lot of Netflix nights, Teleparty is genuinely fine: it is free, and a Premium tier adds video chat on top. Last verified: May 2026.
SyncUp takes a different approach. It syncs play, pause, and seek within about 200ms over a WebSocket connection, with no Premium upsell gating the basic experience. It also handles YouTube, Twitch, and Kick without any extension at all, so the same room can jump from a Netflix episode to a YouTube clip. If you want a closer comparison, the Teleparty alternative page lays out the tradeoffs.
