Desktop and LAN web dashboard for Claude Code hook events

Claudehub Monitor

A desktop and LAN web dashboard that shows what Claude Code is doing in real time — across every repo and machine on your network.

claudehub-monitor is the central collector: Claude Code hooks POST lifecycle events to it over HTTP, and it surfaces them as an animated desktop card, system sounds, a scrolling history, a usage quota toast, and a live web page you can open from your phone.

  Claude Code (any repo / any machine)
        │  hook fires  →  claudehub-hooks  →  HTTP POST /event
        ▼
  claudehub-monitor  ──►  desktop flash card + toasts + sounds + history (SQLite)
        │
        └─►  web dashboard  ◄── browser on the LAN (SSE live updates)

Quick start

1. Start the monitor (once per machine):

pip install claudehub-monitor
claudehub          # short alias
claudehub-monitor  # full name (same command)

2. Wire hooks into each repo you use with Claude Code:

pip install claudehub-hooks
claudehub-hooks install
claudehub-hooks install --url http://192.168.1.50:7070/event   # remote monitor

3. Open Claude Code in that repo — events flow to the monitor automatically.

Test hook connectivity:

python .claude/hooks/claude_hook.py --test

Install

Monitor (claudehub-monitor):

pip install claudehub-monitor
claudehub          # short alias
claudehub-monitor  # full name (same command)

Hooks (claudehub-hooks — separate package, stdlib only):

pip install claudehub-hooks
claudehub-hooks install

Components

Package / path	Role
claudehub-monitor (claudehub/monitor.py)	Monitor: HTTP server, desktop UI, web dashboard, SQLite store.
claudehub-hooks	Pip installer that writes .claude/hooks/claude_hook.py + settings.json entries.
claudehub/dashboard.html	Web dashboard page (served at /).
monitor_config.json	Example monitor config (copy to ~/.claude/monitor_config.json).
.claude/hooks/monitor_config.json	Per-repo hook transport config (written by claudehub-hooks install).
~/.claude/claude_events.db	SQLite history + per-session status (auto-created).

Hook events

claudehub-hooks install registers these Claude Code hooks:

Event	When it fires	Monitor behavior
SessionStart	Session begins	Card shows “Session Started”; history entry
UserPromptSubmit	User sends a message	Thinking — ring animation, persistent toast
PostToolUse	Tool used (matcher: Edit|Write|NotebookEdit|MultiEdit|Read)	Reading (Read) or Editing (others); brief flash → back to thinking
Stop	Turn completes	Done — green tick, ding, clears session
StopFailure	API / runtime error	Error — red card, pong sound
Notification	Claude needs input	Waiting — persistent ask toast
PermissionRequest	Allow/deny dialog shown	Waiting — permission toast + orange card
PermissionGranted	User approved a tool	Resumes Thinking; history shows “Allowed ✓”
PermissionDenied	User denied a tool	Resumes Thinking; history shows “Denied ✗”
PreToolUse	Tool about to run	Resolves pending permission → Thinking (implicit allow for sub-tools)

Hook self-test (claude_hook.py --test) sends __test__ — shown on the card as a purple “Test” flash (not recorded in history).

Event payload (from hooks)

Hooks POST JSON to POST /event:

{
  "event": "PostToolUse",
  "datetime": "<ISO-8601 UTC>",
  "session_id": "<str>",
  "host": "<hostname>",
  "cwd": "<working dir>",
  "files": ["<path>"],           // PostToolUse
  "prompt": "<first 500 chars>", // UserPromptSubmit
  "tool_name": "<tool>",         // PostToolUse / Permission* / PreToolUse
  "command": "<cmd>",            // Permission* / PreToolUse
  "notification_type": "<type>", // Notification
  "error_type": "<type>",        // StopFailure
  "error_message": "<msg>"       // StopFailure
}

Status model

Each surfaced status maps to colour, icon, and animation on the desktop:

Status	Trigger (hook event)	Colour	Desktop animation
Thinking	UserPromptSubmit	blue	rotating arc ring
Reading	PostToolUse (Read)	teal	sweeping scan bar
Editing	PostToolUse (Edit/Write/…)	blue	rippling bars
Waiting	PermissionRequest / Notification	amber	persistent ask toast
Allowed	PermissionGranted / PreToolUse (after approve)	green	ding; back to thinking
Denied	PermissionDenied	red	thud; back to thinking
Done	Stop	green	✓ tick + ding
Error	StopFailure	red	pong

Read/Edit briefly flash, then the card returns to Thinking until the turn ends (Stop) — mirroring how Claude actually works. The desktop card shows the status name; the history table and web feed show the matching icon.

Usage toast

When Claude Code OAuth credentials exist (~/.claude/.credentials.json), a fixed top-right toast shows subscription quota:

• 5-hour session and 7-day weekly utilization (%)
• Reset times for each window
• Refreshed every 5 minutes (one minimal Haiku probe call per refresh)

If credentials are missing, the toast is skipped.

Run it

claudehub
claudehub-monitor
python -m claudehub

The app starts hidden in the system tray by default (the HTTP server and web dashboard run regardless). Double-click the tray icon to open the window; "Minimize to Tray" or closing the window hides it again; the tray menu's Quit exits. Only one instance runs per machine.

Web dashboard (view on the go)

With the monitor running, open from any device on the LAN:

http://<monitor-ip>:7070/

It shows a live grid of active sessions, the last prompt, and a recent-activity feed — pushed over Server-Sent Events (auto-reconnecting), with a JSON snapshot for the initial load.

Open TCP 7070 on the monitor machine's firewall:

New-NetFirewallRule -DisplayName "Claude Monitor" -Direction Inbound `
  -Protocol TCP -LocalPort 7070 -Action Allow

HTTP API

Method / path	Purpose
POST /event	Ingest one hook event (from claudehub-hooks dispatcher).
GET /	The web dashboard.
GET /api/status	Active sessions snapshot + last prompt (JSON).
GET /api/events	Recent events feed (JSON).
GET /events/stream	Live event stream (SSE).
GET /health	{"status":"ok"}.

Configuration

Monitor (claudehub-monitor)

Copy monitor_config.json to ~/.claude/monitor_config.json, or set CLAUDE_MONITOR_CONFIG to point at a file:

{
  "transport": { "http": { "enabled": true, "url": "http://127.0.0.1:7070/event", "timeout_s": 2.0 } },
  "monitor":   { "http_host": "0.0.0.0", "http_port": 7070, "history_max": 50, "start_hidden": true },
  "logging":   { "level": "INFO", "file": "", "max_bytes": 1048576, "backup_count": 5 },
  "sounds":    { "enabled": true }
}

Monitor env vars (override the file): CLAUDE_MONITOR_CONFIG, CLAUDE_MONITOR_PORT, CLAUDE_MONITOR_HOST, CLAUDE_MONITOR_SOUNDS, CLAUDE_MONITOR_LOG_LEVEL, CLAUDE_MONITOR_LOG_FILE.

Logs and the SQLite database default to ~/.claude/.

Hooks (claudehub-hooks)

Per-repo transport config lives at .claude/hooks/monitor_config.json (created by claudehub-hooks install). Point hooks at a monitor on another machine:

{
  "transport": {
    "http": { "url": "http://192.168.1.50:7070/event" }
  }
}

Hook env vars (override the file):

Variable	Default	Meaning
CLAUDE_HUB_URL	http://127.0.0.1:7070/event	Monitor endpoint
CLAUDE_HUB_TIMEOUT	2.0	HTTP timeout (seconds)
CLAUDE_HUB_HTTP_ENABLED	true	Set to false to silence all hooks
CLAUDE_HUB_CONFIG	—	Path to a monitor_config.json override
CLAUDE_HOOK_LOG_LEVEL	INFO	Dispatcher log level
CLAUDE_HOOK_LOG_FILE	~/.claude/claude_hook.log	Dispatcher log path

Multi-instance & reopen recovery

The monitor tracks status per session in SQLite, so:

• Several Claude instances (local or remote) can report at once — the card shows the latest, the history/web distinguish by host + session.
• If you close and reopen the monitor mid-turn, it restores the in-progress state from session_status; a 2-second watchdog idles a session that goes silent.

Requirements

• Python 3.11+ (monitor); Python 3.10+ (hooks)
• claudehub-monitor: PySide6 and anthropic (installed automatically)
• claudehub-hooks: stdlib only
• Windows for sounds (winsound); silently disabled elsewhere.
