Lumen, a watch party with no account required

Field notes

The page supports synchronized playback from YouTube, Rutube, VK Video, direct links, and files uploaded into a room. It distinguishes open rooms, which anyone can enter, from closed rooms shared by invite link, and says uploads, chat history, and room contents disappear when the room closes. The site identifies WebRTC and Socket.IO as part of its implementation and lists Telegram contact, while Discord is marked as forthcoming.
