croc is a very simple but super useful utility, which helps with occasional file transfers between two computers. When you need to send a few files to a friend on another computer or in another country – this might just be the easiest way. No need to setup HTTP or FTP servers, Samba or NFS shares, or register at one of the million web services that provide such functionality.
croc is written in Go and is compiled for a variety of operating systems, include Linux, Windows, and macOS. It even has a simple GUI for those who wants it.
