Localsend

LocalSend is a cross-platform utility designed for secure, peer-to-peer file transfers between devices on the same local network. By establishing direct, encrypted communication channels, the application enables users to share files without relying on external servers, cloud storage, or active internet connectivity.

The project distinguishes itself through a unified codebase that supports native-looking interfaces across desktop and mobile operating systems. It utilizes automated peer discovery to identify available devices on a subnet and employs end-to-end encryption to ensure data integrity and confidentiality during every transfer.

The software suite includes comprehensive build orchestration, allowing for the generation of native installation packages for Windows, macOS, Linux, Android, and iOS from a single source. Additionally, the project maintains multi-language support through a structured, community-driven localization system that decouples text strings into external files.
