Open-source cross-platform file sharing over local network
LocalSend is a free, open-source application for secure peer-to-peer file and message sharing between nearby devices over your local network. It works on Windows, macOS, Linux, Android, iOS, and Fire OS without requiring an internet connection or third-party servers. Each device generates TLS/SSL certificates for encrypted HTTPS communication, making it a privacy-first alternative to AirDrop that works across all operating systems.
