About this tool
A button that stopped working, a trigger that doesn't go all the way, or a stick that moves your character on its own? Connect the controller: each button lights up when pressed, triggers show their pressure as a percentage and sticks draw their position. Nothing to install.
When to use it
Diagnose stick drift
A worn stick sends a small movement even at rest: the drift test measures it as a percentage.
Check a used controller
Before buying, test every button, trigger and the vibration in seconds.

How to use
- Connect the controller over USB or pair it via Bluetooth.
- Press a button so the browser detects it.
- Press every button and push each stick in every direction.
- Let go of the sticks and run the drift test, then vibration.
How it works
The test uses the browser's Gamepad API, which reads the controller state about sixty times per second. Recognized controllers (Xbox, PlayStation, most recent models) follow the “standard” layout, so their buttons are named; others are numbered.
For drift, the tool records the stick positions for 2 seconds at rest: above 8% on average, the stick is considered drifting. Vibration uses the controller's motor when the browser allows it (mainly Chrome and Edge). Nothing is sent over the Internet.
Tips for best results
- Test over USB first: on Bluetooth, a low battery can cause dropouts.
- Rotate each stick in a full circle: the trace should reach the edge all around.
- A small value at rest (under 5%) is normal: games ignore it with a dead zone.
- For keyboards and mice, use ZanaKit's dedicated tests.
Common problems and fixes
The controller doesn't show up
Press a button after connecting it: the browser waits for an input. Try another cable or port, then another browser.
The stick drifts
Clean it with compressed air or isopropyl alcohol while rotating it; if drift remains, raise the in-game dead zone or have the module replaced.
Vibration doesn't work
Safari and Firefox don't always support it. Try Chrome or Edge; over Bluetooth, some controllers only vibrate with their own software.
Frequently asked questions
Which controllers work?
Any your system recognizes: Xbox, PlayStation (DualShock, DualSense), Switch Pro, 8BitDo and most generic USB gamepads.
What is stick drift?
A stick that sends movement while you're not touching it, often due to wear. The drift test measures it.
Do I need to install software?
No. The test runs in the browser, on a computer or a phone if the controller is connected to it.
Can I test several controllers?
Yes, each connected controller is shown separately.
Is my data sent anywhere?
No, the controller state is read and shown in your browser only.
