WebSocket Visualizer is a Chrome extension designed for developers to enhance their debugging processes. This tool integrates seamlessly into Chrome DevTools, providing a dedicated tab for real-time monitoring of WebSocket communications. It captures all WebSocket messages, categorizing them by event type and displaying crucial details such as event time, direction, and message content. This organized approach aids developers in understanding client-server interactions without altering application code or relying on external libraries.

Key features include the ability to intercept all WebSocket connections, display messages in an easy-to-read card format, and provide real-time statistics on active connections and message flow. The extension also supports flexible filtering, allowing users to focus on specific events, and offers options to pause and resume data streams for in-depth analysis. The interface is user-friendly, featuring modern design elements and multilingual support, making it a valuable tool for anyone working with real-time data applications.
