About UltimatePCTools

UltimatePCTools is a free collection of browser-based diagnostic and testing tools for PC hardware. Every tool runs directly in your browser — there is nothing to download, no account to create, and no data sent to our servers.

Our mission

PC hardware testing used to require expensive software or complicated setup. We believe every gamer, developer, and everyday computer user should be able to check their keyboard, mouse, monitor, and network connection in seconds — for free.

How our tools work

All tools use standard browser APIs (Web Audio API, Canvas API, Pointer Events, etc.) to measure hardware performance. Results are generated entirely client-side; we never collect or store your hardware data.

Accuracy

Browser-based measurements have inherent limitations compared to OS-level profiling. Our tools are designed to give accurate relative comparisons and useful diagnostic information, not laboratory-grade measurements. Every tool page explains the methodology and the limitations of browser-based testing.
