Tools I actually
use and trust

A Linux package that ships PuTTYgen and other PuTTY utilities — most useful for converting OpenSSH .pem keys into the .ppk format required by WinSCP and PuTTY.

A Windows GUI client for transferring files to Linux/Unix servers over SFTP, SCP, and FTP — without touching the command line.

A command-line tool for syncing files and directories to and from cloud storage providers — Google Drive, S3, Dropbox, OneDrive, and dozens more — using an rsync-like syntax.

A fast, versatile file-copying tool that syncs files and directories locally or over SSH, transferring only the differences between source and destination.

An interactive process viewer for Linux. A better alternative to top with a visual layout, color coding, and mouse support.
