About HWProbe

HWProbe is a free, open-source suite of browser-based hardware testing tools. It tests gamepads, keyboards, mice, monitors, microphones, and speakers — entirely in your browser using standard Web APIs.

How It Works

Every test runs 100% client-side. Your hardware data never leaves your device — there are no servers processing your inputs, no analytics tracking what you test, and no accounts required. The tools use native browser APIs like the Gamepad API, Web Audio API, MediaDevices API, and requestAnimationFrame to read hardware state in real time.

Why We Built This

Most hardware testing tools require downloads, run intrusive system-level software, or collect data unnecessarily. We wanted a simple alternative: open a URL, test your hardware, get results. No installs, no sign-ups, no data collection.

Open Source

The entire codebase is open source and available on GitHub. You can inspect every line of code, verify our privacy claims, and contribute improvements.

Who Maintains HWProbe

HWProbe is independently branded and maintained. Development is sponsored by OneSpiral, an independent software studio focused on developer tools and open-source infrastructure.
