gFTP vs SmartFTP

gFTP is a free, multithreaded file transfer client for *NIX-based machines, known to run on Linux distributions. It supports FTP, explicit and implicit FTPS, SSH2 SFTP, and FSP. Users can choose a GTK interface or a text interface, launched with the gftp-gtk and gftp-text commands. The text interface can download a directory and its subdirectories in one run, and transfer automation is listed. SSH2 SFTP support requires the OpenSSH client. For FTPS connections to servers using self-signed certificates, the FAQ describes disabling SSL peer verification or adding the CA public key to the OpenSSL certificates directory. The documented build process uses Meson and Ninja, with GTK 3 as the default UI build. Settings and bookmarks go under the gftp configuration directory in line with the XDG Base Directory Specification. The client logs the log-window contents to gftp.log and purges the file when the program starts. The project lists 56 language translations and directs bug reports to GitHub issues. Its plan costs nothing.
