Socket Wrench is a super simple, bare-bones, downloadable, cross platform, desktop GUI application (yes, it's Electron), which makes testing websockets easy. I wrote this to scratch a personal itch, and after having friends and colleagues find it useful, decided to clean it up a bit, make it more user friendly, and released for public use.
Multiple connections multiplexed into a single view. Makes it easier to see how one client's messages impact other clients.
Complete message history. Makes it easy to review past sessions and re-use previous messages.
Independent view, type and sending formats. Allows you to type yaml, send as xml and view it as json.
Custom headers for initial HTTP connection.
Cross platform, offline, desktop application available for Mac OS X, Linux and Windows.
Socket Wrench is currently available in the following distributions:
