Joy2g is a free online platform for watching videos and listening to music together with friends and family, wherever they are. It synchronizes playback so everyone in a room can share the experience in real time, with built-in chat for talking and texting as they watch. Users can create temporary rooms that last up to 24 hours, public rooms, or a permanent personal room after signing in. Invitations are shared through a room link, and the service says there is no limit on the number of viewers.

Joy2g supports content from YouTube, Spotify, Google Drive, SoundCloud, TikTok, Twitch, and Dailymotion, as well as direct media links and uploaded files, which are deleted after 24 hours. A Chrome extension can help add videos from other websites, while a low-latency screen-sharing option is available for content that cannot be embedded. Members can also save videos and build a personal library. Joy2g is accessible without a download and requires no subscription.
