jsCPUInspector

Everything your computer can tell you about itself, in one window — from the processor down to the last thing plugged into a USB port. No terminal, no commands to remember.

Nine tabs, and a live view across the top that shows what every processor core is doing right now.

• Processor: sockets, cores and threads, each core with its own clock
• Cache levels drawn to scale, and which cores share them
• Code name, generation and manufacturing process
• Graphics: every card and chip, with clock, temperature and load live
• The connected monitor: make, model, size and its native resolution
• Mainboard, chipset, BIOS and firmware type
• Memory: every module with size, speed, part number and timings
• Drives: capacity, partitions, free space, read and write speed live
• PCI: which card sits in which slot, and how fast it is connected
• USB: every device on every port, with its speed and power draw
• Network: addresses, link speed, traffic per second, Wi-Fi signal
• Temperatures, fan speeds and voltages, named by where they sit
• Saves the whole report as a text file you can send on
• 44 languages, light and dark theme, colours to your taste

▶ ONE-TIME SETUP

Snap packages may only see very little of the computer at first. Without the one-time setup below these stay empty: mainboard and BIOS details, all sensors and temperatures, and the network interfaces.

One command grants read access. It downloads nothing, installs nothing and changes none of your data — the app may only see more, not do more:

sudo sh -c 'for i in hardware-observe system-observe network-observe; do snap connect jscpuinspector:$i; done'

The app tells you the same thing on first start and offers to copy the command for you. It works without it; the affected entries simply stay empty and say so. No restart needed — a click on Refresh is enough. To undo, use "snap disconnect" instead of "snap connect".

▶ WHAT THIS SNAP CANNOT DO

A Snap is never allowed to ask for the administrator password, and two things need it: the health data of your drives — wear, spare capacity, power-on hours, written and read totals — and the serial numbers of the machine and its parts. Everything else is there. For those two as well, use the .deb, RPM, Flatpak or AppImage version from www.budbrain.de — there the app can ask for the password and read them.

Supported systems:

• Any Linux desktop with X11 or Wayland
• x86_64 (64-bit)
