Onicord

Onicord is an open-source desktop app for voice, video, chat and screen sharing. It uses a peer-to-peer mesh instead of central servers, so rooms need no accounts, cloud servers or phone numbers. Participants connect directly over encrypted channels, and peers help keep a room running and its history in sync if the original host goes offline.

It is for people who want a private alternative to Discord-style chat, with end-to-end encryption (AES-256-GCM), local encrypted storage of profiles and history, and WebRTC voice with Opus audio. Screen sharing, file transfers and a synchronized music jukebox are included, along with dashboard widgets and an addon format (.onipkg).

The app is built with Electron, React and Hyperswarm and is licensed under GPL-3.0. Releases are available for Windows, Linux and macOS, and it includes an MCP server so AI assistants can read diagnostics and control voice actions.
