a small relay for a simple idea
Three strangers, three networks, one room.
One person is on office wifi. Another is on mobile data across the country. A third is behind a home router that's never let anything in. None of that matters here — they type the same room number and room IP, pick a name, and they're in the same conversation.
How a room comes together
-
1
Agree on a room number and room IP
Whoever starts the conversation picks a room number and a room IP and shares both with everyone who should join — over text, email, wherever.
-
2
Everyone enters the same two values, with any username
No accounts, no invite links to click through. Each person just needs a name for themselves — it only has to be unique inside that room.

The room opens, wherever people are
Office wifi, home broadband, mobile data — the room doesn't care. Messages arrive for everyone in it, live.
A quick honest note: a browser can't dial an arbitrary IP address directly — no website can, that door is closed for everyone's protection. So the "room IP" you enter works as a second shared key, alongside the room number, that this server uses to place everyone in the correct room. It's the same idea video-call apps use behind the scenes, just written in plain terms here.
Open your room
Pick any room number and room IP with your group. First one in creates the room; everyone after just joins it.
