Netcat GUI v1.3 is a lightweight graphical frontend for the classic netcat (nc) networking utility, aimed at making TCP/UDP connections, port listening, and data transfers easier for users who prefer a GUI over command-line. Below is a concise article covering what it is, key features, installation notes, usage examples, and security considerations.
