croc: fast, secure, cross-platform file transfer
getcroc.com
croc enables sending files or text between two devices with end-to-end encryption, no network setup, and no user account. The tool works via CLI or a web interface, generates a shareable code, and supports multi-file, folder, and resumable transfers. It stands out for its ease of use, cross-platform support, and a user experience often considered more polished than Magic Wormhole.
