About WebSocket Kong Client
WebSocket Kong is a web-based tool designed for efficient and reliable real-time WebSocket testing and development.
It provides robust features including the ability to manage multiple WebSocket sessions, send, save, and copy JSON messages, edit messages across multiple tabs, and monitor activity through a structured split-pane log interface.
Additionally, users can export saved JSON messages to a file for backup or sharing purposes, and import them at any time to restore previously stored data. A convenient Clear button is also provided to instantly clean the log message panel for better readability during debugging or testing.
