The WebSocket Testing Gap Chrome DevTools Doesn't Fill

The Network tab in Chrome DevTools displays read-only WebSocket traffic but cannot intervene to send malformed payloads or simulate disconnects for real-time features like live collaboration and trading interfaces. A new browser extension acts as a transparent proxy by injecting content scripts that wrap native WebSocket objects within the page context without external servers or certificates. Developers define string or regex replacement rules in a side panel to modify outgoing frames before they hit the wire while inspecting incoming messages instantly.
