Best LAN Messenger — Offline-Capable Messaging
The LAN messenger is your team’s private chat hub that runs inside your local network. Unlike cloud chat apps, a LAN messenger keeps communications on-prem, maximizing control and working even when the internet is down. If you operate in regulated environments, classrooms, factories, hospitals, or air-gapped offices, an intranet messenger is a perfect fit.
