Game and Device Tests
Test yourself and test your hardware. Every tool on this page runs in the browser with no download and no account: measure your click speed, reaction time and aim, or check that a keyboard, mouse, screen, camera or microphone actually works before it matters.

About Game & Device Tests
The performance tests — click speed, reaction time, typing speed and aim — use the browser high-resolution clock, so the numbers are measured in real milliseconds rather than rounded to the nearest animation frame. Each one explains what a typical score looks like, because a number without a benchmark tells you nothing.
The hardware tests answer the question you actually have: is this thing broken? The keyboard tester lights up each key as you press it so a dead key is obvious, the mouse test detects the double-click fault that worn switches develop, and the screen test fills the display with flat colour so a stuck pixel has nowhere to hide.
Camera and microphone checks matter most in the two minutes before a call. Both show a live preview or level meter so you can see the device working, and neither records or uploads anything — the stream is handled by your browser and ends when you close the tab.
Game & Device Tests FAQs
Do these tests need any download or plugin?
No. Every test is plain web code that runs in the page. There is nothing to install, no extension, and no account, which also means nothing to uninstall afterwards.
Are the results accurate?
The measurements are as accurate as the browser allows, using a high-resolution timer. What they measure includes your hardware: a 60 Hz monitor adds up to 16 ms of display latency to any reaction test, which is why the same person scores faster on a high refresh-rate screen.
Is my camera, microphone or keyboard input recorded?
Never. Key presses, clicks, video and audio are processed inside the page on your own device and are not transmitted anywhere. Any score kept between visits is stored in your own browser and can be cleared with your browsing data.
Do these tests work on a phone?
Most of them. Click speed, reaction time, aim and the screen test all work with taps, and the camera and microphone tests work exactly as they do on a desktop. The keyboard and mouse testers need physical hardware to be worth running.
