Campfire

Super simple group chat, without a subscription. And you get the code, too.·once.com

Campfire is an installable, self-hosted group chat system that you run on your own server. It offers rooms, @mentions, direct messages, mobile support via web/PWA, and dark mode. Since users get the source code, they can customize it and own their data, with no recurring subscription fees.
