LocalSend is a free, open-source, cross-platform app that lets you securely share files and messages with nearby devices over your local Wi‑Fi network — no internet connection required, and no external servers involved. Think of it as an AirDrop alternative that works across Windows, macOS, Linux, Android, and iOS at the same time. The app uses a REST API with HTTPS encryption and generates its own TLS/SSL certificate on each device on the fly, so your transfers are private even without a router with special security settings. On first launch LocalSend automatically discovers every other device on the same network running the app; just tap the recipient, pick your files or type a message, and the transfer begins instantly. There is no account to create, no cloud upload, and no file size cap imposed by the app itself — throughput is limited only by your local network speed. LocalSend is available through every major package manager (Winget, Scoop, Chocolatey, Homebrew, Flathub, Snap, AUR, Nixpkgs) as well as the Google Play Store, Apple App Store, Amazon Appstore, and direct EXE/DMG/APK/AppImage/DEB/TAR installers from GitHub. The app also includes a portable mode (place a settings.json next to the executable) and a hidden start option for tray-only use. The latest stable release is v1.18.2 (August 2026).
