Wire is a secure communications platform combining instant messaging, file sharing, voice calls and video conferencing. It is designed for individuals and organisations that need confidential communication across multiple devices.
The application uses end-to-end encryption to protect messages, calls and shared content. Its Messaging Layer Security (MLS) implementation provides a standards-based approach to managing encryption keys in group conversations, while supporting communication between participants using different devices.
Wire provides applications for desktop and mobile platforms, together with browser-based access. The Linux desktop client is built using Electron and provides comparable functionality to its Windows and macOS counterparts. However, Wire describes the Linux application as an experimental build and does not provide official support for it.
The platform can be deployed using Wire’s hosted service or, for organisations with appropriate infrastructure, within a self-hosted environment.
This is free and open source software.
