Overview
A simple TCP/UDP client designed for quick debugging. Supports connecting to remote systems as well as listening (note that Chrome itself does not currently allow for listening TCP sockets).
All of this is in the browser. No stupid external websites to do the connections for you. Works offline/local/etc...
Inspired by the venerable netcat project by *Hobbit*.
