PS4 Controller Test — DualShock 4 Buttons & Sticks

Test any controller online: press buttons to light them up, watch live stick crosshairs, measure stick drift against a deadzone circle and try vibration.

Connect a controller and press any button on it — browsers only reveal gamepads after real input.

This page opens the gamepad tester for the PS4 DualShock 4: connect it with a USB cable or over Bluetooth, press any button and the live grid shows every control the browser receives.

The DualShock 4 follows the standard mapping: Cross on button 0, Circle on 1, Square on 2, Triangle on 3, L1/R1 on 4 and 5, and the analog L2/R2 triggers on 6 and 7 with live values from 0.00 to 1.00. Share, Options, both stick clicks, the D-pad, the PS button and the touchpad click round out the layout — the touchpad's touch surface itself is not visible to web pages, only its click.

Aging DualShock 4 sticks often develop drift, so turn on the deadzone circle, let both sticks rest and read the idle offset for each one. The vibration button drives the pad's two rumble motors where the browser supports it; the lightbar color cannot be changed from a web page, so this tester does not pretend to.

Accepted Formats & Rules

  • Live buttons grid polled from navigator.getGamepads() — pressed state plus fractional values for analog triggers.
  • Two stick crosshairs with a toggleable deadzone circle, per-stick idle offset readout and raw axis values.
  • Dual-rumble vibration test through the controller's vibration actuator, feature-detected with an honest not-supported note.

Key Benefits

✓ Works with any pad the operating system sees: Xbox, DualSense, DualShock, Switch Pro and generic USB or Bluetooth controllers.
✓ Honest drift measurement: a 10% deadzone ring plus a numeric idle offset per stick instead of a vague "looks off-center".
✓ Tested controls stay marked: every button that ever registered keeps a highlight, so you always see what is left to press.

Use Cases

  • • Check a second-hand controller before paying: press every button and pull both triggers to see their fractional values respond.
  • • Measure stick drift: release both sticks and read the idle offset — a stick resting outside the 10% deadzone circle drifts.
  • • Find out whether weak rumble is the game's fault or the pad's: run the dual-rumble vibration test right in the browser.
