Each one reads the events your browser already receives and flags the faults people look for: drift, chatter, double clicks, and dead pixels.

Nothing Leaves Your Device

How It Works
Each test listens to the events your browser already receives from your device: key presses, mouse clicks, pointer movement, and controller input. 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. The webcam test shows your camera's picture on this page only, and the screen tests draw patterns full screen with no flashing.
Questions
Is anything I type or click sent anywhere?
No. Every test runs in your browser on your device. Keystrokes, clicks, and mouse movement are never uploaded or saved.
Do I need to install anything?
No. Open a test in a current version of Chrome, Edge, Firefox, or Safari and it works right away.
Does it work on a phone?
The controller tests work on phones with a controller paired over Bluetooth. The keyboard and mouse tests need a physical keyboard or mouse; a Bluetooth one connected to a phone or tablet works.
Is it free?
Yes. The site is supported by ads and affiliate links.
Do you have a microphone test?
Yes, on our sister site Soundlevel, which has tests for microphones and sound levels.
