Description
AltSendMe is a modern, open-source, peer-to-peer (P2P) file transfer application designed to make sharing files frictionless, fast, private, and unlimited. Built with powerful networking technologies, it allows you to send files directly between devices, no servers, no accounts, no upload limits.
All transfers are end-to-end encrypted using QUIC + TLS 1.3, ensuring that only you and the recipient can access the shared files. Whether you’re sending large media files, documents, or directories, AltSendMe delivers unparalleled privacy and speed — for Windows, macOS, and Linux users.
