WiFiRoom: The internet, but for one Wi-Fi: chat, files, games, live

Hi Product Hunt! WiFiRoom started as "who's on my Wi-Fi, as pixel characters" and grew into this because a hostel floor, a game night, a classroom and a flight all want the same thing: everyone in the same place, on the same Wi-Fi, able to talk, share and play without the internet, accounts or a cloud in the middle. What's in the room: channels (kept on the host device, so late arrivals see history) and end-to-end encrypted DMs; file sharing where you allow a folder on your own device and people fetch from it, nothing uploaded anywhere; voice calls; chess, Ludo, Crazy Eights and Texas Hold'em with a scoreboard for the night; a program with now/next, polls and sign-up sheets; and Live, where one device plays a video or shares its screen and everyone watches in sync. Built for public Wi-Fi with strangers on it: your name is tied to a key your browser keeps, with a fingerprint next to it so nobody can pass for you; a sealed one-time code carries your identity to another device; the host can lock the room or remove someone. It's open source (MIT), plain HTML/JS served by one Node process, no build step, on Phaser, Preact, tweetnacl, Socket.IO, chess.js and pokersolver. `npx wifiroom --share` and you're hosting. I'd love to hear what you'd run it for.
