About this extension
byob (Bring Your Own Binge) is a free, open-source Watch2Gether alternative. Create a room, share the link, and watch together.

What the extension does:
  • Syncs non-YouTube/Vimeo streaming sites (Crunchyroll, anime sites, etc.) by hooking into <video> elements
  • Shows a sync bar with play/pause controls, progress bar, time counter, and ready count on external player pages
  • Displays a "Play the video to start syncing" toast to guide users through the autoplay gesture
  • Shows SponsorBlock segment colors on YouTube's embedded seek bar
  • Scrapes page metadata (title, thumbnail) from external sites for display in the room

What byob.video supports (with or without the extension):
  • Synchronized YouTube playback — play, pause, seek in real-time
  • Vimeo — native embedded player with full sync support
  • Direct video file URLs (.mp4, .webm, .ogg, .mov, .mkv) with a built-in synced HTML5 player
  • Video queue with drag-to-reorder and auto-advance
  • SponsorBlock integration with per-room category settings (auto-skip or show in bar)
  • Room history and persistence across server restarts
  • Dark/light theme
  • Random usernames, renamable, visible in user list

How it works:
  1. Create a room at byob.video
  2. Share the room link with friends
  3. Paste video URLs and watch together
  4. For non-YouTube sites, click "Open Player Window" and the extension syncs playback automatically
