WebSocket Debugger + Security Workbench

WebSocket Workbench is a compact Chrome extension for authorized WebSocket debugging and security evidence collection.

Use it to connect to WebSocket endpoints, inspect inbound and outbound frames, replay selected text messages, and document findings without leaving Chrome. It supports extension-context sockets, a direct page overlay for page-context sockets, passive DevTools discovery, bounded replay artifacts, and redacted evidence notes.

Security Lab checks require explicit authorization confirmation and are intended for your own applications, approved internal testing, and authorized security review. The extension is not an exploit automation tool, does not weaken authorization boundaries, and keeps sensitive diagnostics visible to the user.

Core workflows:

- Connect from the popup, side panel, DevTools panel, iframe overlay, or direct page overlay.

- Capture observed WebSocket handshakes and frames through the authorized DevTools flow.
