This seems to be still in active development phase

https://nodejs.org/api/inspector.html#integration-with-devtools.

https://sachinkasana.medium.com/http-2-network-inspection-in-node-js-debug-like-a-pro-3812fc3a7b67

For me it works with flag --experimental-network-inspection

with node v24

node --inspect-brk --experimental-network-inspection -e "fetch('https://google.com')"

Now in the chromium based browser type chrome://inspect then click the discovered target, then the Network tab in Chrome Dev Tools for node should show entries.

Broadcast stack may look like:
