1. Connect and wake the controller
Plug in with USB or pair with Bluetooth, then press any face button once. Some browsers only expose a pad after the first interaction.

Focused controller tools
Use the same live tester core with dedicated pages for drift troubleshooting, deadzone tuning, and controller-specific checks.
Controller Drift Test
Spot idle movement before it affects your aim.
Watch real-time stick magnitude, peak offset, and recommended deadzone values while the sticks are untouched.
Deadzone TestDial in a threshold that feels stable without hiding input.
Compare live stick movement against a user-controlled deadzone ring and see how close you are to center.
Xbox Controller TestCheck standard mapping, triggers, bumpers, and stick travel.
Ideal for wired or Bluetooth Xbox pads on desktop browsers that expose the standard Gamepad API layout.
PS5 Controller TestInspect DualSense buttons, adaptive trigger values, and stick response.
Verify your browser sees the controller correctly and confirm analog input looks clean and centered.
Gamepad API core
Built on the browser primitives you asked for.
The site is powered by navigator.getGamepads(), gamepadconnected, gamepaddisconnected, and a requestAnimationFrame refresh loop.
Static deploy
Fast to ship on GitHub + Cloudflare Pages.
No backend, no database, and no build pipeline. The root directory can be deployed directly as a static site.
How to use the tester
The flow is simple, but these three steps give you the cleanest read on drift, deadzone, and button health.
2. Release both sticks
For drift checks, keep your thumbs off the sticks and watch the live magnitude and peak idle offset numbers for a few seconds.
3. Sweep every input
Press A/B/X/Y, LB/RB, Start, Select, D-pad directions, and then roll both sticks through full circles to confirm travel and trigger range.
FAQ
Short answers for the most common controller testing questions.
Do I need to install anything?
No. GamepadTester.tools is a plain static website that reads controller input directly from the browser.
Why is my controller not showing up?
Browsers often require a button press after connection. If it still does not appear, reconnect it and try a current Chrome, Edge, or Firefox build.
What does the suggested deadzone mean?
It is a lightweight estimate based on the highest idle stick offset observed after your last reset, plus a small safety margin.
Can this test Xbox and PS5 controllers?
Yes. Standard-mapped Xbox pads and PS5 DualSense controllers usually work well when connected through a supported desktop browser.
