Free Gaming Tools
Quick checks for your mic, controller, keyboard, mouse and monitor. They run in your browser, need no sign-up, and show measurements rather than diagnoses.
Which tool do I need?
Start from the problem you are trying to solve.
| Tool | Use it when | Works with |
|---|---|---|
| Mic Test | Your voice is too quiet, too loud or not being picked up. | Browser microphone |
| Gamepad Tester | A button, trigger or stick seems off, or the camera drifts. | Wired or Bluetooth controller |
| Keyboard Tester | A key doesn't register, repeats, or you want to check rollover. | Any keyboard |
| CPS Test | You want to measure or practise your clicking speed. | Any mouse or trackpad |
| Sensitivity Converter | You're moving between FPS games and want the same aim feel. | Your sensitivity and DPI |
| eDPI Calculator | You want one number to compare your mouse settings. | Your sensitivity and DPI |
| Dead Pixel Test | A new or old screen might have dots that don't change. | Any display with a browser |
How these tools work
Every tool on this page runs inside your browser. Your microphone audio, controller input, keystrokes and clicks are processed in the tab and never uploaded, and there are no accounts. Where a tool needs a browser feature, such as the microphone or the Gamepad API, it says so and explains what to do if your browser doesn't support it.
The tools measure; they don't diagnose. A stick drift reading tells you how far a stick sat from centre, not why. A dead pixel test shows you a dot, not whether a maker will accept a return. Each page explains how to read the result and what to try next, and links to the guides behind it.
