About Corny Chat
Corny Chat is an open-source audio space for Nostr users, built as a fork of Jam, itself described as an open source alternative to Clubhouse and similar audio rooms. Users can log in with existing Nostr accounts, including via a NIP-07 browser extension or as anonymous users, and their name, avatar and Lightning address are pulled from their Nostr profile data (kind 0) for use throughout the room.
Rooms can be customized with background pictures, color themes and emoji reactions, and hosts can schedule future events published as Nostr calendar events. The project also covers live activity and chat tied to Nostr events, and zapping between users, though the roadmap lists some zap and chat-related items as not yet complete. The repository includes installation, update and privacy documents for those who want to host their own server.
