Plug it in with a USB data cable or pair it over Bluetooth. Browsers only reveal a controller after a button press, so press A or ✕ if nothing appears. Nothing is sent anywhere.

All buttons and axes · 0 buttons pressed
Press every button once: each one gets a tick when it registers. Values show analog pressure from 0.00 to 1.00.
Health tests
1. Stick drift
Measures where each stick settles when nobody touches it, and checks for buttons or triggers that read as pressed. Pass: under 5% of full travel. Warning: 5–10%. Fail: 10% or more.
Not run yet.
2. Circularity
Rotate each stick slowly around its outer edge. Measures how far the edge strays from a perfect circle. Pass: up to 10% average error. Warning: up to 20%. Fail: above 20% or a direction that can't reach 75% of full travel.
Not run yet.
3. Vibration
Plays a rumble. The strong motor is the heavy, low rumble in the left grip; the weak motor is the finer buzz on the right.
Connect a controller to test vibration.
4. Input update rate
Estimates how often the browser receives new data from the controller while you move a stick.
Not measured yet.

More tests for PlayStation controllers
Connect a DualSense, DualSense Edge or DualShock 4 directly for what the standard gamepad connection hides: motion sensors, touchpad, battery and the true report interval, plus adaptive triggers and lights on a DualSense. Your browser asks which device to allow, and the permission lasts until you close the tab. This page only reads the controller and sends effect commands (trigger effects, light bar, player lights), never calibration or firmware, and it resets them when you leave.
Decoded from published formats (the Linux hid-playstation driver and SDL); not yet tested on a real controller. Over Bluetooth, deep mode switches the controller to its full report format until it reconnects, and asks first: if another app or game stops seeing it, turn the controller off and on.
Not connected.
Motion sensors
Tilt and turn the controller: the model follows it, and the graphs show the gyroscope (turn rate, degrees per second) and the accelerometer (g) on each axis. Put it down flat and run the rest check to measure gyro drift.

Touchpad
Draw on the touchpad with one or two fingers. Each finger gets its own colour and the ID the controller gives it; a dead strip shows up as a gap in the lines. Press the pad to test its click.
No touch yet.
Adaptive triggers (DualSense only)
Pick an effect, then press L2 or R2. Resistance pushes back from the start point; click is a section of resistance that gives way, like a trigger pull; vibration buzzes the trigger from the start point. The bars show where each trigger is.
Light bar and player lights
Battery
The level the controller reports, in 10% steps, and whether it is charging. It updates live, so plug in a cable to check the charging port.

Report interval
How often the controller sends a report, from the controller's own clock and from the time each report reached this page. This is the report interval, not end-to-end input lag: it leaves out the time a press takes inside the controller, in the game and on the screen.
