Keyboard, mouse & controller

Input device tests.

Use these eight tools to inspect keyboard, mouse and gamepad input, measure typing or click speed, convert sensitivity, or time a response. The pages show the events received and the calculations behind their results. Everything runs in this tab; nothing is uploaded.

• Instrument

  Keyboard Tester

  See which key events reach the browser and check for repeated presses that may indicate chatter.

• Instrument

  Typing Test

  Measure words per minute, raw speed, accuracy and consistency, with the formula for each result shown on the page.

• Instrument

  Mouse Test

  Check buttons, wheel movements and pointer movement, including unintended double-clicks.

• Instrument

  Click Test

  Clicks per second over a fixed window, with the count and the rate both stated.

• Instrument

  Spacebar Counter

  Count spacebar presses and measure their rate. Check whether a single press registers more than once.

• Instrument

  Gamepad Tester

  Inspect live button, trigger and axis values, and look for stick movement while the controls are at rest.

• Instrument

  Mouse Sensitivity Converter

  Convert sensitivity between titles and see eDPI, cm per 360 degrees and the formulas used.

• Instrument

  Reaction Time Test

  Compare five response times in milliseconds, their spread, and the browser's measured frame interval.
