Yes. The scanner is open-source, runs entirely on your machine, and only reads hardware info — it cannot modify, install, or delete anything. The JSON output contains no personal data, just component specs and temperatures.

Does it need internet?

The scanner itself works offline and saves results to your Desktop. You only need internet to upload the JSON file to our dashboard for analysis.

What Windows versions are supported?

Windows 10 and Windows 11 (64-bit). The scanner uses WMI and standard Windows APIs. It must be run as Administrator to access detailed hardware info like temperatures and BIOS settings.

How accurate is the analysis?

The analysis engine references your exact hardware specs, current drivers, BIOS settings, and temperatures against a database of 176+ CPUs and GPUs with 15+ detection rules. You get specific, actionable recommendations for your exact build — not generic advice.
