Practical checks for the devices you use every day.
This site brings together browser-based tests for keyboards, mice, displays, microphones, cameras, touchscreens, internet connections and IP/network details. Open a tool when something feels off, or use one to understand how a device behaves.
A useful first check
Most tools run in your browser, with no account or installer. They can help you spot behavior worth investigating, but results depend on your browser, operating system, hardware and test conditions.
Measurements with context
A web test can only observe what the browser and connected device expose. These tools are designed to make that information easier to inspect; they are not laboratory instruments or official warranty verdicts.
Privacy that reflects how the tools work
Keyboard, pointer, touch, microphone and camera test signals are processed in the browser. IP, DNS, WebRTC, proxy and map tools make specific network requests to provide their results. The Privacy Policy explains which services are involved.
