WebSocket Debugger + Security Workbench

About

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.
- Inspect text frames and binary wire previews with payload length, hex preview, and base64 preview.
- Save socket recipes and selected outbound text messages as local replay artifacts.
- Replay selected text messages manually against a connected socket.
- Export redacted evidence notes for debugging and security reports.
- Use Debug Lab CSP tools only for explicit, selected-tab debugging.
