Watch X

Cross-platform desktop hardware monitor for Windows, macOS, and Linux — CPU, GPU, memory (including Windows DDR5 SPD identity), temperatures, fans, disks, network, battery, and processes — with an always-on overlay HUD when you minimize the main window.

Why Watch X?

Most “system monitors” either show SMBIOS marketing strings for RAM, invent DRAM die names, or force you online during install. Watch X focuses on honest readings and offline Windows installs:

• Prefer measured sources (SMBIOS, SPD, RAPL / Energy Meter) over guesswork
• Never invent DRAM die / IC part numbers when evidence is missing
• Windows installer ships self-contained helpers — no download mid-setup

Features

• Live dashboard — CPU, discrete GPU, memory, thermals, fans, disk, network, battery, processes
• Windows DDR5 SPD — JEDEC / XMP / EXPO advertised profiles via elevated spd-helper + official PawnIO (bundled offline)
• CPU package power — Windows Energy Meter / RAPL when available
• Overlay HUD — keep key metrics visible after minimize / close-to-tray
• Offline Windows packaging — Electron + self-contained .NET helper + unmodified PawnIO_setup.exe inside Setup.exe

Quick Start

Download (recommended)

1. Open Releases
2. Pick your platform:
   • Windows: WatchX-*-Setup-x64.exe (offline installer) or *-Portable-x64.exe
   • macOS: WatchX-*-mac-arm64.dmg (Apple Silicon) or *-mac-x64.dmg (Intel)
   • Linux: .AppImage or .deb
3. Install / run — no account required

Develop from source

git clone https://github.com/H0Andy/watch-x.git
cd watch-x
npm install
npm run dev

Electron downloads slowly? Use a mirror (example):

$env:ELECTRON_MIRROR="https://npmmirror.com/mirrors/electron/"
npm install

Platforms

OS	Installer	Notes
Windows x64	NSIS Setup + Portable	Bundles SPD helper + official PawnIO installer (silent local install)
macOS arm64 / x64	DMG + ZIP	Unsigned local/test builds — Gatekeeper may need “Open Anyway”
Linux x64	AppImage + deb	chmod +x for AppImage

• Packaging details (Windows offline): see README_CN.md or scripts in package.json

Honesty policy (hardware identity)

• SPD-advertised XMP/EXPO ≠ current runtime timings
• DRAM die stays unknown unless uniquely evidenced — never filled from marketing PN alone
• Missing sensors show an explicit unavailable state — no fake numbers
