About

Advanced WebSocket Client is a Google Chrome extension designed to help construct custom WebSocket requests and handle responses for directly testing your WebSocket services.

It supports the JSON request/response format, and its main feature is that you don't have to strictly follow RFC formatting rules.
You can use single quotes, double quotes, or no quotes for string keys and values, as well as trailing commas in object literals.

Additionally, it supports both single-line and block comments, just like in JavaScript.

Shortcats:
    F1 - fullscreen on/off
    F2 - line wrapping on/off
    Ctrl+Q - fold/unfold a code block
    Alt+Ctrl+J or Cmd+Ctrl+J - format JSON
    Cmd+/ or Ctrl+/ - comment/uncomment line/block
