ABOUT GEARCHECK LAB
GearCheck Lab is a browser-based hardware diagnostics project built to make common input, display, audio and camera checks easier to run, easier to understand and easier to repeat. The core idea is simple: when a modern browser already exposes useful device information, a user should not need to install an unknown utility just to answer a basic troubleshooting question.

What GearCheck Lab is for
The site provides practical diagnostics for controllers, keyboards, mice, displays, speakers/headphones, webcams and microphones. The tools are intended for questions such as: Is my controller stick drifting? Does this button register? Are both triggers reaching their full range? Can my browser see the controller? Are several keyboard keys detected at the same time? Does my mouse produce repeatable movement activity? Is a display pixel stuck? Are audio channels reversed? What webcam resolution is the browser receiving? Is the microphone producing a live input signal?
Where possible, the answer is shown as direct browser telemetry rather than a vague score. We prefer visible measurements, repeatable steps and explicit limitations over claims that a browser test cannot support.
What makes the project different
GearCheck Lab is designed around functional tools first. A page is not useful merely because it targets a search phrase. Public diagnostic pages are expected to provide an actual test, explain what is being measured, show how to interpret the result, identify common limitations and link to related checks that help narrow down a problem.
The visual design intentionally resembles a diagnostic console: dark near-black panels, cyan/teal telemetry and clear PASS, WARNING or FAIL-style states where a simple status is justified.
Privacy-first by design
Many tests use browser APIs such as Gamepad, Keyboard, Pointer, Web Audio and MediaDevices. Hardware readings are processed on the page whenever practical. Camera and microphone pages are built for local preview or signal analysis rather than upload or recording.
Browser permission controls remain in the user's hands. A device permission can be denied, revoked or stopped without creating a GearCheck Lab account.
What GearCheck Lab is not
The site is not a manufacturer calibration utility, hardware repair service, clinical hearing test, laboratory colorimeter, USB protocol analyzer or warranty authority. Browser-level results are useful evidence, but they are one layer in a larger hardware and software chain.
When a result matters, we encourage repeat testing, comparison with another connection method or browser, and confirmation in the manufacturer's own software or operating-system tools where appropriate.
How the tools are developed
Tools are built from browser capabilities that can provide direct, understandable feedback. New public diagnostics are expected to have a clear user problem, working interaction, mobile/responsive behavior where relevant, original explanatory content and a known limitation model.
Changes are versioned in the project repository and deployed only after the site build remains valid. Methodology and editorial policy pages describe the standards used for interpretation and content.
Core principles
Functional firstA diagnostic page should do something useful, not exist only to attract search traffic.
Measured, not magicalWe show browser-visible data and avoid pretending it is a deeper hardware measurement than it really is.
Explain limitationsDrivers, browsers, operating systems, firmware, wireless links and device mappings can affect results.
Local when practicalDevice telemetry should remain in the browser when a server is unnecessary.
Repeatable checksUsers should be able to repeat the same steps and compare results across settings or connections.
Clear next stepsSuspicious readings should lead to sensible troubleshooting rather than alarmist conclusions.
