Instant messaging that runs without the public internet

Ant Messenger runs inside a closed network: the server is deployed on your own machines and the clients install without the public internet.

The client covers Android, iPhone or iPad, macOS (M1) and Windows. The desktop app authorises by scanning a QR code from the phone app - there is no password login to configure.
