About

gamepadcontrollertest.bond is a free set of input-device testers that run entirely in your web browser. It began with one goal: give people a fast, honest way to check whether a controller, mouse, or keyboard actually works, without installing anything or handing data to anyone.

What it does

The controller tester reads your gamepad through the browser Gamepad API and shows every button, stick, and trigger live, plus a stick-drift test that measures the resting offset of each stick. The mouse tester checks buttons, scroll, double-click chatter, and click speed. The keyboard tester highlights keys, tests rollover, and reads key codes.

How it works

Everything happens on your device. The tools use standard web APIs (Gamepad, Pointer, Keyboard events) and never send your input anywhere. There is no account, no login, and no upload. That is a deliberate design choice, not a limitation.

How it is funded

The site is supported by display advertising. Ads are placed around the tools, never inside the testing area, and are sized so they do not shift the page while you work. We would rather show a clean, fast page than a cluttered one.
