Local messaging apps for Windows PC users

Although instant messaging has become a native part of popular online services like Facebook and Google, its proliferation has not completely wiped out dedicated local chat apps for PC.

How can I communicate with someone without Internet?

As shown above there are still some great options when it comes to local network messaging apps. They do not require an Internet connection or servers but act more as Intranet messengers.

To this purpose, they rely on corporate networks which also have the benefit of serious encryption and airtight security.

What messaging app works without internet?

1. Softros LAN Messenger – Local LAN messenger (RDP & file exchange)


Developed by Softros Systems, Softros LAN Messenger is a secure instant messaging application for user-to-user or user-to-group communications and file exchange.

The program requires no server and works through corporate networks. You can chat with multiple users with Softros’ LAN chat rooms or connect with a single user through its classic single-message window.

The app also supports offline messaging and uses the AES 256 encryption algorithm to secure your chat messages from eavesdroppers.

Meanwhile, the group broadcast feature lets users notify their contacts or groups about an event.

Softros LAN Messenger also provides users the option to log messages to the local drive or to a centralized file server.

Since the program requires no Internet connection, corporate users can avoid wasting their time on unimportant communications with friends outside their work.

You can also avoid hefty Internet charges and firewall breaches with the app. The program supports Microsoft/Citrix Terminal Services and Microsoft Active Directory.

With Softros LAN Messenger, you can also call for remote assistance through its desktop sharing feature.
