If you’re troubleshooting a keyboard, mouse, or touchscreen, these two free browser-based tools can make basic testing quick and easy.

• Online Keyboard & Mouse Tester — useful for checking whether individual keyboard keys and mouse inputs are being detected correctly.
• Touch Screen Tester — helps check touchscreen responsiveness and identify areas where touch input may not be registering properly.

Both are simple tools that can be useful when diagnosing hardware input problems without installing additional software.
