Jelly Party 作者： Sean

Jelly Party turns a video you can already watch into a watch party.

Open Jelly Party beside the video, start a party, and send your friends the invite link. Everyone lands on the same video. When the leader changes videos, every party tab follows automatically, and play, pause, and seek carry to every screen. Chat and the people list live in the browser's native sidebar, so the page you are watching is left alone.

• Private through one long, unguessable link. No accounts, profiles, or room codes.
• One clearly marked leader picks the video and can hand the lead to anyone in the party.
• Everyone stays at the same moment: play, pause, and seek are shared.
• Late joiners arrive at the current moment instead of starting at the beginning.
• Video changes and leadership handovers remain visible in the party history.
• Works on popular streaming services and other pages with an HTML5 video.
• Free and open source.

Jelly Party asks for access to a video site only when it needs to find and control that site's video. Anyone with the unguessable party link can join, so share it only with the people you want to invite.
