Keyboard tests for different devices

Laptop keyboard test

Check built-in laptop keys, arrows, modifiers and common system keys without installing software.

Gaming keyboard test

Verify WASD, Shift, Ctrl, Space and multi-key gaming combinations for ghosting or rollover limits.

Mechanical keyboard test

Check every switch after a build, repair or keycap change and spot keys that never register.

Keyboard ghosting test and N-key rollover test

A keyboard ghosting test checks whether a combination loses one or more key presses. N-key rollover, often shortened to NKRO, describes how many simultaneous keys a keyboard can report. Hold several keys at the same time and compare the highlighted keys with the keys you physically press.

Keyboard tester for 60%, 65%, 75%, TKL and 100% layouts

Choose the layout that is closest to your physical keyboard. Compact 60% and 65% boards omit many navigation keys, 75% boards keep a compact function and navigation area, TKL removes the numpad, and a 100% full-size layout includes the navigation cluster and numeric keypad.

FAQ

Frequently asked questions

How do I test if a keyboard key works?

Press the key while this page is active. If the matching virtual key lights up, the browser received that key press.

Can this test detect keyboard ghosting?

Yes, within the limits of what the browser receives. Hold several keys at once and check whether every key remains highlighted.

Why does the Fn key not appear?

Fn is usually processed by keyboard firmware and does not generate a normal browser KeyboardEvent.

Does this work for laptop and gaming keyboards?

Yes. It works with laptop keyboards, membrane keyboards, wireless boards and many gaming keyboards in modern desktop browsers.

Is anything I type uploaded?

No. This version processes key events locally in your browser and does not send your typing to a server.

What is an online keyboard tester?

An online keyboard tester is a browser tool that shows whether physical key presses reach the browser. It is useful for checking dead keys, modifiers and multi-key combinations.

How do I test multiple keyboard keys at once?

Hold the keys together and watch the virtual keyboard. If every pressed key remains highlighted, the browser received the full combination.

Can I test a 60%, 65%, 75% or TKL keyboard?
