Socket Inspector is a free Chrome extension designed to enhance the debugging experience for WebSocket applications. It integrates seamlessly with the browser's DevTools, providing developers with essential tools for inspecting WebSocket traffic in real-time. Users can view a comprehensive log of sent and received messages, enabling quick searches and filters to isolate specific interactions. The extension supports both WS and WSS connections, making it versatile for various applications.

In addition to traffic inspection, Socket Inspector offers custom message simulation capabilities through a built-in text editor that supports JSON formatting. Developers can simulate messages being sent from either the server to the UI or vice versa. The traffic blocking feature allows users to pause live connections, facilitating a more focused debugging process. Furthermore, the extension supports dark mode, ensuring compatibility with users' preferred Chrome DevTools theme.
