Last updated: 2026-10-08

Free online controller tester for buttons, sticks, drift, polling rate, triggers, vibration and reports.

ControllerTest is an independent browser-based controller diagnostic website. It is not affiliated with Microsoft, Sony, Nintendo, Valve or controller manufacturers.

## Testing workflow

1. **Connect and wake:** Connect by USB, Bluetooth or adapter, then press any controller button so the browser can expose the Gamepad API device.
2. **Press, move and sample:** Press every button, pull both triggers, rotate both sticks, then collect drift, circularity and polling samples in the same browser session.
3. **Review and export:** Review the health score, failing metrics and export options for resale checks, repair notes or support tickets.

## Controller Tester Online & Gamepad Health Check

Page: https://controllertestonline.com/
Source last updated: 2026-07-22

Use this free gamepad tester to run a full controller health check in your browser. Test buttons, analog sticks, triggers, stick drift, deadzone, polling stability, vibration support and exportable report data.

ControllerTest reads the Gamepad API locally. It can reliably show input state, stick center offset, trigger values and browser-exposed haptics.

Polling rate is estimated from browser timestamps, so use it for setup comparisons rather than hardware-lab certification.

## Stick Drift Test Online

Page: https://controllertestonline.com/stick-drift-test/
Source last updated: 2026-07-22

Keep your hands off both analog sticks and run an 8-second rest sample. The drift test reports left and right center offset, drift severity, sample confidence and a recommended game deadzone.

The tool measures analog stick distance from the center while the controller is idle. A small offset is normal. A large or unstable offset means the game may receive movement even when you are not touching the stick.

ControllerTest does not repair drift. It gives a repeatable browser-based reading and a deadzone suggestion that can help you decide whether to adjust settings, clean the stick, or replace the module.

## Controller Polling Rate Test

Source last updated: 2026-06-25

Move a stick for 8 to 10 seconds to estimate browser-visible gamepad Hz, input interval, jitter, sample count and stability. Use the same browser and PC to compare USB, Bluetooth and 2.4G controller modes.

ControllerTest samples the browser Gamepad API and converts visible timestamp or input-change deltas into average Hz, peak Hz, interval, jitter and stability.

The result is a browser-layer estimate, not a raw USB analyzer capture. Browser scheduling, display refresh, drivers, Bluetooth stacks and USB power management can all change the number you see.

## Controller Deadzone Test

Run an 8-second rest sample to calculate a practical game deadzone. Use the recommendation, safety margin and threshold circle to hide stick center noise without masking real movement.

A good deadzone is slightly larger than the controller's idle stick offset. Too low and drift causes unwanted movement. Too high and aim or steering feels sluggish near center.

Run the stick drift sample first. ControllerTest adds a small safety margin to the largest observed center offset and reports that as a practical starting point for game settings.

## Controller Circularity Test

Source last updated: 2026-06-25

Choose a stick, start the circularity pass and rotate smoothly around the full outer gate. The tool visualizes trace shape, coverage, circularity error, sample count and whether the stick reaches full range evenly.

Circularity testing focuses on the stick's outer travel. A controller can pass a center drift check but still have flat spots, weak diagonals or limited range near the physical gate.

ControllerTest reads browser-visible Gamepad API axes during a timed rotation. Use the result to compare left and right sticks, tune outer-deadzone style settings and decide whether cleaning, calibration or repair is worth checking.

## Controller Vibration Test

Page: https://controllertestonline.com/vibration-test/
Source last updated: 2026-09-23

Connect a controller, press any button, then run a short vibration test. Check weak and strong rumble and learn what the result means.

Vibration depends on browser, operating system, controller model, connection mode and driver behavior. A controller can rumble in native games while still not exposing a compatible haptic actuator to the browser.

ControllerTest checks browser-exposed haptic capability and sends short pulses through the Gamepad API path when available. It does not measure physical motor force, vibration latency or DualSense adaptive trigger resistance.

## Xbox Controller Tester

Page: https://controllertestonline.com/xbox-controller-test/
Source last updated: 2026-06-25

Test Xbox Series, Xbox One, Xbox Elite and Xbox-style PC controllers. Check A/B/X/Y, bumpers, triggers, sticks, D-pad, vibration support and export a health report.

Most Xbox controllers expose a standard browser mapping: A, B, X, Y, LB, RB, LT, RT, menu, view, sticks and D-pad.

If the controller does not appear, connect by USB first, press a button, then retry Bluetooth or the Xbox wireless adapter.

## PS5 Controller Test

Source last updated: 2026-09-23

Connect your DualSense to test PS5 button input, stick drift and L2/R2 trigger travel. Follow the checks below to understand what each browser reading means.

The browser can read standard Gamepad API input when the DualSense is exposed by the operating system.

Adaptive trigger resistance is not normally controllable through the standard browser API. Use USB for the most consistent first test.

## Switch Controller Test

Page: https://controllertestonline.com/switch-controller-test/
Source last updated: 2026-06-25

Test Switch Pro Controller and Joy-Con input in the browser. Check stick drift, circularity and button mapping before deciding whether a controller needs recalibration or repair.

Switch controllers can expose different browser mappings depending on OS, Bluetooth stack and driver.

Joy-Con drift is commonly a center-offset issue, so the stick drift sample and deadzone guidance are the most important checks on this page.

## Controller Input Test

Page: https://controllertestonline.com/controller-input-test/
Source last updated: 2026-07-22

Use the live input test to inspect button presses, trigger values and analog axes. This is the fastest way to confirm whether the browser sees your game controller correctly.

Each button should light up once when pressed and turn off cleanly when released. Analog axes should return near 0.00 at rest and move smoothly toward -1.00 or 1.00 at full travel.

If a button never changes, a trigger does not reach full range, or an axis jumps while idle, run the drift and deadzone tests before deciding whether the controller needs service.

## Gamepad Tester Online

Page: https://controllertestonline.com/gamepad-tester-online/
Source last updated: 2026-07-22

Open the browser gamepad tester, press any button to connect, then check live buttons, analog sticks, trigger values, drift, deadzone and vibration support.

The tester reads the Gamepad API locally and turns browser-visible input into a practical controller health check for PC and console-style gamepads.

Use it before buying a used gamepad, after changing drivers, or when a game does not seem to read buttons, sticks or triggers correctly.

## Joystick Tester Online

Page: https://controllertestonline.com/joystick-tester/
Source last updated: 2026-06-25

Use this joystick tester to watch analog stick axes live, check whether the stick returns to center, and confirm the outer gate reaches full range.

A healthy analog stick should rest near the center, move smoothly across the axis range, and return without large jumps or stuck values.

If the stick rests off-center, run the drift and deadzone tests. If it does not reach the outer edge evenly, use circularity to inspect gate travel.

## Controller Latency Test

Page: https://controllertestonline.com/controller-latency-test/
Source last updated: 2026-06-25

Use browser-visible polling and input updates to compare controller latency symptoms across USB, Bluetooth and 2.4G setups on the same system.

A web page cannot measure end-to-end display latency like a hardware rig. It can still show update stability, dropped input patterns and polling differences between connection modes.

For useful comparisons, test the same controller in the same browser, close heavy apps and repeat the sample after switching between USB, Bluetooth and adapters.

## Gamepad Mapping Test

Page: https://controllertestonline.com/gamepad-mapping-test/
Source last updated: 2026-06-25

Use the mapping test to see which browser button index, axis and trigger value changes when you press each control on the gamepad.

Browsers, operating systems and drivers can expose the same controller with different button labels or axis order, especially for Switch, generic and specialty controllers.

The mapping page helps you document what the browser sees before changing game settings, emulator bindings or repair notes.

## Switch Joy-Con Drift Test

Page: https://controllertestonline.com/switch-joy-con-drift-test/
Source last updated: 2026-06-25

Connect a Joy-Con or Switch Pro controller, leave the stick untouched, and measure center offset before checking deadzone and circularity.

Joy-Con drift often appears as a center offset: the stick reports movement even while untouched. The browser can show that offset when the controller is exposed through the Gamepad API.

Use the result as a condition check, not a repair claim. Severe drift usually needs cleaning, calibration in system tools, warranty service or stick module replacement.

## PS Controller Calibration Guide

Page: https://controllertestonline.com/ps-controller-calibration/
Source last updated: 2026-06-25

Use browser diagnostics to check whether a PlayStation controller shows drift, trigger range issues or deadzone symptoms before changing game settings.

ControllerTest cannot write firmware settings or recalibrate a PlayStation controller. It can show browser-visible stick center, axis movement, trigger travel and vibration capability.

Use those readings to decide whether to adjust in-game deadzone, try USB, clean the stick, run platform tools or seek repair.

## Reports and data

Reports, JSON, CSV and share cards are generated on the user's device. These guides do not contain a user's live readings or a public results database. An assistant cannot see a controller or diagnose its condition from this site description alone. Users can choose to provide relevant report values separately.
