Getting Started

Inputest brings together browser tools for checking keyboards, mice, displays, microphones, speakers and webcams. It also includes reaction-time and click-speed tests. These tools help you observe input and output; they cannot certify that a device is fault-free.

Use a current browser, connect the device you want to check, and close applications that could compete for camera or microphone access. Start with one test, repeat a suspicious observation, and compare another browser or device before drawing a conclusion.

More about these steps
  1. 01

    Choose a test

    Open a tool from Browse Tools. Expand Mouse Test to find its individual checks, or use Guided Testing to visit the seven hardware-oriented tools in order.

  2. 02

    Follow the instructions

    Perform the requested key presses, clicks, movements or visual checks. Camera, microphone and speaker tests start only after you activate their controls.

  3. 03

    Understand the results

    Read the measured values alongside each tool’s limitations. Repeat unexpected results under similar conditions before changing hardware or system settings.

  • Easy to use
  • No installation required
  • Browser-based testing

Understanding Results

Observed events, not a diagnosis

A registered key or click means the browser received an event. A missing event may be caused by the device, operating system, focus, permissions or browser restrictions. A warning is a reason to investigate, not a confirmed hardware failure.

Compare like with like

Repeat measurements with the same browser, display, power mode and input device. Keep the tab active and reduce background load. Change one condition at a time so you can tell what affected the result.

Keep the units in mind

Milliseconds describe time; lower reaction times are faster. Hz describes a rate per second; FPS describes video frames per second. CPS is clicks per second. Browser event rates and frame cadence should not be mistaken for direct hardware specifications.

Privacy & Permissions

Camera and microphone access

Webcam Test requests camera access when you start it. Microphone Test requests audio access when you press Record. Allow only the device you intend to test. If access is blocked, use your browser’s site-permission controls and check the operating system’s privacy settings; the exact controls vary by browser and system.

What happens to samples

The current webcam implementation displays a live stream and creates snapshots in the browser. Microphone recordings are assembled in the browser for playback and download. These capture paths do not upload media. This statement describes those features, not a blanket promise about all network activity or future versions of the site.

End access and manage saved files

Use Stop Camera or Stop Recording and leave the tool when finished. Camera tracks are also released when the tab is hidden; returning does not restart the camera. Speaker playback stops when the tab is hidden or the page is left. Downloads remain wherever your browser saved them. Revoke camera or microphone permission in the browser’s site settings if you no longer want to allow access.

Troubleshooting

The microphone is not detected

Check the connection, hardware mute switch, system input device and site permission. This tool uses the browser’s default audio input rather than an in-page device selector. Select the desired input in your system or browser, close competing apps, then retry Record.

Open test

The camera shows a black screen

Wait for the live preview to initialize, check the lens cover and lighting, and confirm the selected Camera Device. Close apps using the camera. Try Auto resolution if a requested mode fails; virtual cameras may expose different constraints from the physical webcam.

Open test

Some keyboard shortcuts do not register

Click outside search fields and controls, keep this page focused, and try the keys individually. Operating-system shortcuts, Fn keys and browser-reserved combinations may never reach the page. Compare a different keyboard or application before concluding that a switch has failed.

Open test

The mouse produces unexpected clicks

Use Single Click Test and press deliberately once at a time. Compare the recorded intervals, then try Click & Hold Test without releasing the button. Check remapping software, accessibility settings, connection quality and a second device. A flagged short interval alone does not confirm switch damage.

Open test

The scroll wheel behaves inconsistently

Choose a fixed expected direction and scroll only that way inside the test area. Reset before repeating. Intentional reversals, a touchpad, smooth-scrolling software or browser processing can create misleading results. Compare another application and inspect the mouse for dirt or wear if the pattern persists.

Open test

The refresh rate result seems incorrect

Keep the tab visible, close heavy tasks and compare plugged-in and battery power modes. Check the system display setting and which monitor contains the browser. A repeatable browser rate can still differ from the display setting; it is not evidence by itself that the monitor is faulty.
