The Metasploit web interface is a browser-based interface that provides easy access to navigational menus and allows you to change the configuration pages for tasks. You can perform every single task you do in the Metasploit Framework (MSF) in the Metasploit web interface, from performing a discovery scan by using an auxiliary to popping up a Meterpreter.
For those who prefer graphical user interface (GUI) tools for penetration testing, you can use the Metasploit web interface. The web interface is a part of Metasploit CE (free), Metasploit Pro (paid), Metasploit Express (paid), and Nexpose Ultimate (paid). Unlike the more advanced features available in the paid versions of Metasploit, the free CE is the most basic of all.
