LAN Messenger
What LAN Messenger is
LAN Messenger is a free, open-source instant messaging application for people connected to the same local network. It works without a server or internet connection, allowing users on that network to start conversations. Messages can be sent to everyone through broadcasts or directed to selected users. The application also transfers files between network users and archives past conversations for later access. Contacts can be arranged into groups, and users can receive notifications about upcoming events. Its interface supports multiple languages. The maker says LAN Messenger uses AES encryption with RSA. Versions are available for Windows, macOS, and Linux. Downloads include Windows installers, Mac disk images for Apple Silicon and Intel, and Linux DEB and RPM packages. The website directs bug reports and general discussion to GitHub. LAN Messenger is offered on a free plan listed as free, and no free trial is provided.
