LocalSend software is a free and open-source application that allows you to securely share files and messages with nearby devices over your local network. It is a cross-platform software, meaning it can be used on different operating systems. LocalSend does not require any external servers, as everything happens locally on your network. This software is an alternative to AirDrop and provides a convenient way to share files between devices without the need for an internet connection. You can download LocalSend from the official website or from app stores such as the App Store and Google Play.
