pi-network-monitor

Network request monitor for pi coding agent.

Shows every HTTP request that pi and its extensions make — LLM API calls, web searches, content fetches, auth flows — in a live overlay. Useful for understanding what's happening on the network, debugging slow requests, and seeing the full request chain behind tools like pi-web-access.

How it works

Uses Node.js diagnostics_channel to subscribe to undici's request lifecycle events. Since pi and all extensions run in the same Node.js process and use the global fetch(), this captures everything with zero monkey-patching.

Install

pi install npm:@volh/pi-network-monitor

Or from git:

pi install https://github.com/volh/pi-network-monitor

Requires pi v0.37.3+. No dependencies.

Usage

Open with Alt+N or /network.

List view

Each line shows method, status code (color-coded), host + path, and duration.

Key	Action
↑/↓ or j/k	Scroll
PgUp/PgDn	Jump 10 entries
Home/End	Jump to top/bottom
Enter or d	Detail view
f	Host filter
c	Clear history
Esc	Close

Detail view

Full URL (wrapped), HTTP status, TTFB, total duration, timestamps with millisecond precision.

Host filter

Press f, start typing to search (e.g. ant → api.anthropic.com). Matching substring highlighted. Hosts sorted by request count. Enter to apply, Esc to cancel.

Configuration

~/.pi/network-monitor.json:

{
  "shortcut": "alt+n",
  "anchor": "center",
  "width": "60%",
  "maxHeight": "80%"
}

Key	Default	Description
shortcut	alt+n	Keyboard shortcut
anchor	center	Overlay position (center, right-center, top-right, etc.)
width	60%	Overlay width (percentage or columns)
maxHeight	80%	Maximum height

What gets captured

Every fetch() call in the pi process — LLM API calls (any provider), search APIs, content fetches, auth flows, extension traffic. Per request: method, full URL, status code, TTFB, total duration, errors. Stores last 500 requests in memory, not persisted.
