About

LocalSend is a cross-platform app that enables secure communication between devices using a REST API and HTTPS encryption. Unlike other messaging apps that rely on external servers, LocalSend doesn't require an internet connection or third-party servers, making it a fast and reliable solution for local communication.

Download

It is recommended to download the app either from an app store or from a package manager because the app does not have auto-update.
