About WebSocket Sniffer
Say goodbye to the cluttered Network panel and debug WebSockets the elegant way!
Tired of squinting at raw, unformatted WebSocket frames while building real-time web applications (like chat rooms, trading platforms, or live games)?
"WebSocket Sniffer" is a Chrome DevTools extension crafted specifically for frontend developers and QA engineers. It integrates seamlessly into your F12 developer tools, providing a clean, organized interface dedicated entirely to intercepting and parsing bidirectional WebSocket traffic.
✨ Key Features
📡 Real-Time Bidirectional Interception: Accurately captures and categorizes WebSocket Send and Receive events.
🧩 Smart Formatting & Parsing: Say goodbye to messy plaintext! Automatically detects and formats JSON and XML payloads into an easily readable, collapsible Tree View.
⚡️ High-Performance Buffering: Designed for high-frequency data streams (e.g., live tickers, gaming). Built-in data batching and record limits ensure your page maintains peak FPS without any lag or memory leaks.
🥷 Zero-Interference Technology: Utilizes advanced Monkey Patching and API cloaking. It operates silently under the hood without breaking your site's native logic or triggering common anti-debugging mechanisms.
🎯 Dedicated DevTools Panel: Keeps your workspace organized with a custom panel inside DevTools, accessible exactly when you need it without cluttering your main UI.
👨💻 Who is this for?
