LocalSend
A free, open-source app for securely sharing files and messages between nearby devices over a local network, without internet or third-party servers.
LocalSend is a free, open-source application for sharing files and messages with nearby devices on the same local network. It is useful when you need a direct transfer between your own devices without an internet connection or a third-party server. Communication between devices uses a REST API and HTTPS encryption. The project is cross-platform: the README lists Windows, macOS, Linux, Android, iOS, and Fire OS. To try it, install LocalSend on the devices that should exchange files using the listed download options, place them on the same local network, and open the app on both devices. The repository contains the source code and release guidance. The README notes that LocalSend does not include an auto-update mechanism, so updates should be obtained through the recommended app store or package manager. Transfers depend on the local network and the devices being reachable there.
