Drift Radar
Diagnostics Breakdown
Optimal Health
Brand new or hall-effect sensors. Zero noticeable drift in-game.
Normal Wear
Standard potentiometer degradation. Setting a 0.08 deadzone is recommended.
Severe Drift
Mechanical fatigue. Requires deadzone adjustment or hardware cleaning.
Calibration Center
Calibrate thumbstick center-points and trigger sensitivity values
1. Reset Offsets
Keep your controller on a flat surface, release both thumbsticks, and press the 'Calibrate Center' button in the diagnostics dashboard above to nullify resting drift.
2. Set Deadzone
Adjust the software deadzone slider to match your thumbstick's resting error. The deadzone filters out axis jitter for cleaner movement input in competitive play.
3. Scale Triggers
If your triggers are worn out and cannot reach the maximum depth of 1.00, increase the 'Trigger Force' multiplier to scale the raw depth readings accordingly.
Polling Rate Benchmark
Measure your controller's polling rate with our free online Polling Rate Benchmark. Check input frequency monitor response speed, analyze latency and track real-time performance directly from your browser. No download or installation required.

What is a Gamepad Tester?
A Gamepad Tester is a web-based utility designed to read and display inputs from game controllers. By accessing standard browser APIs, the utility displays real-time details of button presses, triggers, and thumbstick axes. Gamers use it to diagnose drift, check button latency, and verify that their controllers are functioning at peak efficiency before jumping into competitive multiplayer matches.
Understanding Analog Stick Dead Zones
A dead zone is a small area around the thumbstick's neutral position where movement inputs are ignored by the game. Dead zones are essential to prevent minor stick drift from moving your in-game camera. If a controller has loose springs or worn-out potentiometers, it will stay outside the default dead zone, causing camera drift. Our tester helps you measure the resting axis values, allowing you to set the perfect in-game dead zone offset.
Why You Should Test Trigger Pressure
Modern gaming controllers utilize analog triggers (L2/R2 or LT/RT) that measure pressure depth. This depth is vital for racing games (throttling and braking) and shooters (hair-trigger firing). If a trigger's internal rubber pad wears down, it might only register up to 80% or 90% pressure even when squeezed completely. GamesPadTesterPro lets you visualize this range as a live percentage to confirm you are reaching full input capabilities.
How to Connect Controllers to PC
For the lowest latency, we recommend connecting your controller with a high-quality USB cable. If you prefer playing wirelessly, turn on Bluetooth on your PC, put your gamepad into pairing mode (e.g., hold Share + PS button on PlayStation, or the sync button on Xbox), and add it as a device. Once connected to your operating system, open our gamepad tester, press any button, and start diagnosing immediately.

Common questions about controller testing and stick drift diagnostics
Simply connect your controller to your computer or mobile device using a USB cable or via Bluetooth. Once connected, press any button on the controller. The web application will immediately detect the gamepad and display live metrics for buttons, triggers, and analog sticks.
Stick drift happens when a controller's thumbstick reports movement inputs even when you aren't touching it. In our diagnostic visualizer, check if the Left Stick or Right Stick dots remain offset from the center crosshair when the stick is in its neutral position. If the axial values (X, Y) are not at 0.00, your controller has stick drift.
For minor stick drift, you can increase the "Inner Deadzone" setting in your game's controller options (e.g. Fortnite, Apex Legends, or Call of Duty). For physical fixes, you can try cleaning the analog stick base using compressed air or isopropyl alcohol, or calibrate the controller in your operating system's hardware settings. Severe drift may require replacing the analog sensor module.
Controller vibration (haptic feedback) over the web requires browser permission and OS driver support. Currently, vibration is supported in Google Chrome, Microsoft Edge, and Opera on Windows and Android. macOS and iOS do not support gamepad rumble in the browser due to operating system limitations.
No downloads are required. GamesPadTesterPro operates 100% inside your web browser utilizing standard HTML5 Gamepad APIs. It is safe, private, and executes entirely client-side on your device without transmitting your inputs to external servers.
