Noodle

A lightweight macOS menu bar app for monitoring and managing Node.js processes.

Features

• Monitor all running Node.js, npm, and npx processes
• View details including project name, script, port, CPU, memory, and uptime
• Energy indicator showing Low/Med/High resource usage
• Stop/Kill processes with SIGTERM or SIGKILL
• Remember recently run processes and restart them with one click
• Auto-refresh every 5 seconds

Screenshot

The app lives in your menu bar and shows the number of running Node processes. Click to open the panel:

Installation

Download Release

1. Download the latest Noodle-vX.X.X.zip from Releases
2. Unzip and move Noodle.app to your Applications folder
3. Open Terminal and run:

   xattr -cr /Applications/Noodle.app

4. Launch Noodle

Note: The xattr command is needed because the app isn't signed with an Apple Developer certificate. macOS quarantines unsigned apps downloaded from the internet.

Build from Source

Requires macOS 13+ and Xcode Command Line Tools.

git clone https://github.com/yourusername/noodle.git
cd noodle
./build.sh

Then move Noodle.app to your Applications folder.

Usage

1. Launch Noodle - it will appear in your menu bar
2. Click the icon to see all running Node processes
3. Use the action menu (⋯) on each process to:
   • Stop (SIGTERM) or Force Kill (SIGKILL)
   • Copy PID or full command
4. Stopped processes are remembered for 7 days and can be restarted
5. Press ⌘R to refresh, ⌘Q to quit

Permissions

On first run, macOS may ask for permissions:

• Accessibility: Not required
• Automation (Terminal): Required only if you want to use the "Start" feature to restart stopped processes

How It Works

Noodle uses system commands to discover Node processes:

• ps - List running processes with CPU/memory stats
• lsof - Find listening ports and working directories

No background daemons, no elevated privileges, no network access.
