Controller Tester

Connect a controller and press any button. Every button, trigger, and stick shows up live.

Connect Your Controller and Press Any Button

Browsers only show a controller after one of its buttons is pressed. Plug it in with USB or pair it over Bluetooth first. Nothing leaves this page.

How to Use It

Connect your controller with USB or Bluetooth, then press any button so the browser shows it.
Press every button once, and squeeze each trigger slowly: the percentage should rise smoothly from 0% to 100%.
Move each stick to its edges, then let go: it should return close to 0.00.

What the Results Mean

Buttons Tested

The counter reaches every button once each has registered a press. A button that never lights up isn't reaching the computer; one that lights up without being pressed is stuck.

Triggers

Analog triggers should move through the whole range without jumps. If a trigger stops short of 100% or never returns to 0%, its sensor or spring is worn.

Sticks

A stick at rest should read within about 0.05 of 0.00 on both axes. More than that is drift, which you can measure with the stick drift test.

Fixes

The Controller Isn't Detected

Press a button with this page open; browsers wait for a press before showing a controller.
Try another USB cable. Many cables only charge and carry no data.
Close Steam or other apps that take over controllers, then reload this page.

A Button or Trigger Doesn't Respond

Update the controller's firmware with the Xbox Accessories app, the PlayStation Accessories app, or a Switch console.
Clean around the button with isopropyl alcohol on a cotton swab and press it repeatedly.

Vibration Doesn't Work

Use Chrome, Edge, or Safari. Firefox doesn't support controller vibration.
Over Bluetooth on some systems, vibration only works with a USB cable.
For the Xbox, PlayStation, and Nintendo vibration settings, see how to test controller vibration.

Questions

How do I test my controller on a PC?

Connect the controller with a USB cable or Bluetooth, open this page, and press any button. The test shows every button, trigger, and stick as you use them, and counts how many buttons you have tested.

Why doesn't my controller show up?

Browsers only show a controller after a button is pressed while the page is open. If it still doesn't appear, check it works in your system's controller settings, try another cable (some are charge-only), or re-pair it over Bluetooth.

Does it work with PS5, PS4, Xbox, and Switch controllers?

Yes. DualSense, DualShock 4, Xbox One and Series, Switch Pro, and most generic controllers work, and the buttons are labeled for the controller you connect. The DualSense touchpad, motion sensors, and adaptive triggers aren't available to web pages.

How do I test vibration?

Press Weak Motor, Strong Motor, or Both Motors. Vibration works in Chrome, Edge, and Safari. Firefox doesn't support controller vibration yet.

How do I check for stick drift?

Let go of both sticks and watch their values: they should read close to 0.00. For a measured result and a deadzone suggestion, use the stick drift test.

Does it work on a phone?

Yes, on Android in Chrome and on iPhone and iPad in Safari, with a controller paired over Bluetooth.
