Free tests for your keyboard and mouse that run in your browser. Nothing you type or click leaves your device.
Each test listens to the events your browser already receives from your device: key presses, mouse clicks, and pointer movement. It shows them as they arrive, measures the timing between them, and flags common faults such as a key that registers twice or a mouse button that double-clicks by itself.
Your browser only passes on what your operating system allows. Some keys, such as Fn, never reach a web page, and each test lists its limits.
No. Every test runs in your browser on your device. Keystrokes, clicks, and mouse movement are never uploaded or saved.
No. Open a test in a current version of Chrome, Edge, Firefox, or Safari and it works right away.
The keyboard and mouse tests need a physical keyboard or mouse. A Bluetooth keyboard or mouse connected to a phone or tablet works.
