ProFTPD (short for Pro FTP daemon) is an FTP server. ProFTPD is Free and open-source software, compatible with Unix-like systems and Microsoft Windows (via Cygwin). Along with vsftpd and Pure-FTPd, ProFTPD is among the most popular FTP servers in Unix-like environments today. Compared to those, which focus e.g. on simplicity, speed or security, ProFTPD's primary design goal is to be a highly feature rich FTP server, exposing a large amount of configuration options to the user.

ProFTPD includes a number of options that are not available with many other FTP daemons. The configuration of ProFTPD is performed in a single main configuration file called /etc/proftpd/proftpd.conf. Due to its similarities to the configuration file of Apache HTTP Server it is intuitively understandable to someone who uses this popular web server.

Especially when it comes for example to real-time monitoring of current user actions and file transmissions, a GUI can be very helpful and superior to the CLI. Some existing GUIs for ProFTPD are (selection):
