Three steps

Live in two minutes

1

Install the agent

A tiny download for Windows, or a one-line install on Linux. Paste your token and you’re done.

2

It scans automatically

The agent reads every component on first launch and sends a secure snapshot — no manual work.

3

Get your score & fixes

A health score, a board map of your machine, and prioritized plain-language fixes appear instantly.

A board map of your actual machine

Not a stock diagram. Every scanned component is pinned to the board and colour-coded by health, so you can see what needs attention at a glance.

  • Live specs on every part — model, speed, temperature
  • Green / amber / red health, right where the part sits
  • Nine subsystems, from CPU to BIOS to cooling

FAQ

Good to know

Is it safe to run?
The agent only reads hardware and system information and sends a secure snapshot. It never changes your settings — you apply the fixes yourself.
Which systems are supported?
Windows and Linux desktops and servers, on x64 and ARM64. The Linux agent installs with a single command and bundles its runtime.
Do I need an account to see my results?
Yes — your scans are tied to your account so you can track them over time and manage multiple machines from one dashboard.
How much does it cost?
The core scan, score, board map and fixes are free forever for up to three machines. Paid plans add fleet scale and history.
