KoalaSync: The Privacy-First Watch Party Extension

Synchronize movies, series, and videos in real-time with friends—no accounts, no tracking, no lag.

Whether you're binge-watching Netflix, catching a Twitch stream, or using custom self-hosted platforms like Emby, Jellyfin, and Plex, KoalaSync keeps everyone perfectly in sync. Lightweight, open-source, and built for absolute data sovereignty.

✨ CORE FEATURES
• Universal HTML5 Sync: Flawlessly synchronize play, pause, and seeking on YouTube, Netflix, Disney+, and virtually any website with a standard video player.
• Smart Binge-Watching (Auto-Sync): The ultimate series coordinator. When a new episode loads, KoalaSync automatically pauses playback in a smart lobby until everyone’s video is ready. No spoilers, no one left behind.
• One-Click Invitations: Generate a smart invite link. Once your friends click it, their extension instantly configures the room credentials and server settings.
• Zero-Latency Protocol: Powered by a custom WebSocket architecture designed for frame-perfect, real-time coordination without buffering loops.

🛡️ UNCOMPROMISING PRIVACY
Built by developers who care about security. We don't want your data.
• 100% Anonymous: No accounts required, no tracking, and zero analytics.
• Zero Persistence: Our official public relay server operates entirely in volatile RAM. No databases, no logs, no watch history.
• Self-Hostable: Take total control. Deploy your own private relay server in seconds using Docker and connect your extension with a single click.
• Pure Performance: Built with clean, dependency-free Vanilla JS to keep your browser fast and resource-friendly.

🚀 HOW IT WORKS (IN 3 SECONDS)
• Open the KoalaSync popup and pick a nickname.
• Click "Create Room" and copy the invite link.
