I ve run into this issue often enough that I finally created my own barebones GUI for testing websockets  It s called Socket Wrench  it supports    multiple concurrent connections to servers  with all responses and connections displayed in the same view    comprehensive message history to enable easy re-use of messages  and  custom headers for the initial connection request     It s available for Mac OS X  Windows and Linux and you can get it from here
