SyncWatch

Watch videos together: sync playback, chat and stay connected with up to 10 friends.

Watch together. Stay in sync. SyncWatch brings your friends to the video you already watch. It synchronizes HTML video playback, pause, seeking and speed for up to 10 participants, with room chat and a customizable Glass Lounge panel. Everyone opens the original video on their own device. SyncWatch does not stream video or audio, provide a media library, or bypass subscriptions and access restrictions. GET STARTED 1. Open a video page and click the SyncWatch toolbar icon. New installations include the SyncWatch relay; you can choose your own compatible server. Existing custom server settings are preserved. 2. Create a room code, connect, and copy an invitation link. 3. Your friend opens the link, checks the server and room, and confirms joining. Everyone needs access to the same video. Site autoplay rules may require clicking Play. MADE FOR YOUR MOVIE NIGHT • Up to 10 participants, without a separate SyncWatch account. • Synchronized play/pause/seek and playback speed, drift correction and reconnection. • Shared controls for two participants. In larger rooms, the host or an assigned controller manages playback; anyone can request a pause. • Room chat with messages up to 200 characters, quick reactions, saved drafts and unread indicators. Chat history is held in the current background session, not a permanent archive. • Friend invitations and optional presence sharing on your chosen server. • A gradient glass panel with Room, Chat, Friends and Style tabs, plus a compact icon when minimized. • English and Russian interfaces. Choose your language in Style; Browser language selects Russian for Russian locales and English otherwise. • Dark, light or system themes; four gradients; two panel sizes; opacity, motion and left/right placement. System reduced motion is respected. • Independent rooms for each tab. Watch solo when you want independent playback while staying in the conversation. • Supported fullscreen panels, quick messages and notifications, including embedded players. Native HTML video has a small ⛶ control. COMPATIBILITY Chrome 120+. SyncWatch detects HTML video and includes adapters for YouTube, PlayerJS, Kodik, Alloha and jut.su. Results depend on the site's current player, advertisements, frame permissions and autoplay policies; every website is not guaranteed. Automatic shared navigation stays within the current viewing site. Supported adapters can coordinate episode/season/audio choices and buffering or advertisements. YOUR DATA The selected relay processes room codes, viewing URLs, content choices, display names, playback commands and chat. Friend presence uses a public installation identifier, signed requests and temporary access information; the private key stays on your device. The default relay uses Cloudflare, and you can choose another server. HTTPS/WSS encrypts transport. The server processes relayed contents; end-to-end encryption is not provided. Data are not sold or used for advertising. No analytics, remote translation service or downloaded JavaScript is included.
