Countdown Web Remote

A browser remote for Countdown that connects directly to the desktop app over WebRTC — NAT hole-punched, peer to peer. No port forwarding, and the timer data never passes through a server.

Deploy the contents of dist/ anywhere on your site.

How a connection is made

1. The desktop app registers with a signaling server under a peer id derived from its session id.
2. You open this page and enter a pairing code: SESSION.KEY.
3. The page connects to that peer id and presents the key in a hello frame.
4. The desktop app answers welcome + snapshot, and everything after that flows over the DataChannel.
