One phone hosts a chat room. Everyone else scans a code and joins from any browser — no app, no account, no internet. When you put it out, every message is gone.
Same Wi-Fi or your hotspot · nothing stored after it ends
What it does
For a class, an office, a trip or a party — everyone in the same place, talking in one room.
Everyone lands in Public, and it’s always there.
Anyone can start a room, with an optional password, or talk one-to-one.
Photos and videos play inline; big files stream straight to disk.
Ask the room something, pin what matters, mute what doesn’t.
Record and send from the browser or the app.
Room creators remove people from their rooms; the host can remove anyone.
See it
The host’s phone serves the whole chat. Friends scan the QR code or open the link on any phone or laptop — nothing to install, nothing to sign up for.
Messages arrive as people join
Under the hood
Your phone becomes a tiny web server on your Wi-Fi or hotspot, and shows a link and a QR code.
They open it in any browser, pick a name, and they’re in — no app, no account.
End the Campfire and every message, room and file is wiped from the phone.
Privacy
Campfire stores nothing after it ends and talks to no server. It isn’t encrypted on the local network, because browsers can’t trust a certificate there; the app says so plainly.
Download Campfire for the host phone. Everyone else just needs a browser.
