Free CPS tester online tools answer a simple but surprisingly addictive question: how many times can you click in one second? CPS stands for clicks per second, and it's a quick way to measure your clicking speed. Gamers use it to warm up, friends use it to challenge each other, and plenty of people just want to see how they compare. Open the tool at the top of this page, choose a test length from 1 to 60 seconds, start clicking, and get your score. It runs in your browser, so there's nothing to download and no account to create.
This page explains how the test works, what counts as a good score, and how to improve your speed without hurting your hand.
Quick tip: warm up your hand for a moment before you test, and stop if you feel any pain or strain. A fast score isn't worth a sore wrist.
You don't need any technical knowledge. Here's the general process:
Don't judge yourself on a single attempt. Your first run is usually a warm-up, and your best scores often come after a few tries once your hand settles into a rhythm.
Everything you need appears on screen during and after your run:
The total number of clicks you've made in the current run.
The time remaining in the test. It counts down from the length you chose.
Your live clicks per second, worked out as the number of clicks divided by the time that has passed so far. It updates about ten times a second, and the value you see when the test ends is your final score.
Your highest CPS for the test length you've selected. Each test length keeps its own best score, so your best 5-second result isn't mixed up with your best 60-second result. Best scores are saved in your browser on your own device, so they're still there the next time you visit.
A small chart under the click box plots your CPS over the course of the run, so you can see whether you started fast and faded, or built up speed over time.
CPS is short for clicks per second. The result is worked out by dividing the number of clicks you made by the number of seconds the test lasted. If you make 50 clicks over 10 seconds, that's an average of 5 CPS.
It's a measure of speed, not accuracy. A CPS test doesn't care where you click inside the click box, only how quickly you can do it. Only normal left clicks are counted, so right-clicks and middle-clicks won't add to your score.
It depends on who you ask and how you click. Most people who try a CPS test for the first time land somewhere in the middle range, and scores climb with practice and technique. Rather than chasing a fixed number, it's more useful to compare yourself with your own earlier results, which is what the Best score box is for.
Run the test a few times and note your typical score. That's your starting point, and it's the number worth beating.
Short tests tend to give higher scores, because you can sprint for a few seconds. Longer tests, such as 30 or 60 seconds, show your steady pace, which is usually lower. When you compare scores with a friend, make sure you both used the same test length.
Your mouse, its switches and its weight all play a part. A light mouse with crisp buttons can feel easier to click quickly than a heavy one with stiff buttons.
If you want to raise your score, it helps to know what other people do. These are the styles you'll hear about most often.
One finger presses the button, the way you use your mouse every day. It's the most comfortable and the most sustainable, though it usually gives the lowest speeds.
You tense the muscles in your hand and arm so that your finger vibrates against the button. It can produce very high bursts, but it's tiring and uncomfortable, and it's harder to control.
Two fingers alternate on the same button, so you get two presses for each movement cycle. It needs a mouse with a button that's comfortable to press with two fingers, and it takes some practice to get right.
You drag a finger across the surface of the button to trigger many clicks quickly. It's popular in some game communities, but it puts extra wear on the button and can be tough on your skin and joints.
Bear in mind that some games and servers have rules against certain techniques or auto-clicking tools, so check the rules of anything competitive before you rely on them.
A relaxed hand clicks faster than a tense one. Sit properly, rest your forearm, and keep your wrist in a neutral position.
A mouse that fits your hand and has light, responsive buttons makes fast clicking easier. If you're using a heavy or worn mouse, the difference can be noticeable.
A few short attempts, with breaks between them, works better than one long grind. Tired hands slow down, and you'll get more out of fresh ones.
Clicking in a smooth, even rhythm usually beats frantic tapping. Try to keep the movement small and relaxed, and use the chart to see whether your speed stays steady through the run.
Repeated fast clicking can strain your hand and fingers. Stop if anything hurts or feels numb, stretch between sessions, and don't push through discomfort. If pain persists, speak to a health professional.
If your score seems too low, or some clicks don't show up, the problem may be your setup and not your speed.
Make sure the mouse is plugged in properly or, for wireless models, that the battery is charged and the receiver is close.
Move the mouse or receiver to a different port on your computer, ideally not through a hub.
A worn switch can miss clicks or register extra ones. Our double click test shows whether one press is being counted twice, and the free mouse tester lets you check each button in turn.
Check your system's mouse settings and any manufacturer software for macros, button assignments or profiles that might interfere with clicking.
Outdated or damaged drivers can cause missed or delayed clicks. Update them from the manufacturer's website, or reinstall them fresh.
If the problem disappears, the cause was a setting or a browser issue. If it follows the mouse, the hardware is the likely culprit.
Every time you press and release a mouse button over a web page, the browser creates an event that the page can read and count. MDN explains the details in its documentation for the click event. The tool adds up those events over the length of the test and divides by the time to work out your score.
Your browser only reports what your system sends it. If your operating system or mouse software filters or changes button presses, the test can only count what reaches the page.
A CPS test only needs to see your clicks on the page, which is the same kind of input any website can see when you visit it. It doesn't need your microphone or camera, and your browser won't ask for special permissions to run it. The tool saves your best scores in your own browser so they're there next time. They stay on your device, and clearing your browser's site data will remove them. As with any site, you can read the privacy policy if you'd like details about what data, if any, is collected during your visit.
Yes. It's free to use, and you don't need to sign up.
No. The test runs in your browser, so you can open the page and start straight away.
Clicks per second. It's your total number of clicks divided by the number of seconds the test lasts.
You can choose 1, 5, 10, 30 or 60 seconds. The 1-second test is selected by default.
The timer starts on your first click inside the click box, and that first click is counted. You can take your time getting ready before you begin.
Once the time runs out, the test is finished and extra clicks are no longer counted. Press Reset, or choose a test length, to start a new run.
It depends on your technique, your hardware and the length of the test, so there isn't one number that fits everyone. A better goal is to beat your own previous results.
You can't sprint for very long. Over a longer test your hand tires, so your average pace drops compared with a short burst.
In your own browser, on your device, with a separate best score for each test length. If you clear your browser's site data, use a different browser, or switch devices, the saved scores won't carry over.
No. The tool counts normal left clicks only.
Yes. Button feel, weight and shape can all change how fast and comfortably you can click, though your technique matters too.
Generally yes, as most trackpads behave like a mouse in the browser. Fast clicking is usually harder on a trackpad, so scores may be lower.
The test is designed for a mouse or trackpad. On a touchscreen you'd be tapping instead of clicking, which isn't a fair comparison, so a computer is the better choice.
If you like testing your gear, there's plenty more to try. Check every button on your mouse with our free mouse tester, make sure your audio is working with the free speaker tester, or browse every free tool on the MechKeyTest homepage.
