Free Device & Hardware Tools
EKO24.NET provides simple browser-based tools for checking common computer, phone and peripheral functions. Test your microphone, camera, keyboard, mouse, speakers and screen without installing extra software.
Test your devices directly in the browser
Use the Microphone Test to check audio input, the Webcam Test to preview your camera, and the Speaker Test to check left and right audio channels.
Check keyboard, mouse and display information
The Keyboard Tester shows detected key presses, while the Mouse Test checks common mouse buttons, movement and scrolling. The Screen Resolution Checker displays screen size, browser viewport, pixel ratio and other display information.
Privacy and browser permissions
Some hardware features, such as your microphone and webcam, require browser permission before they can be accessed. The device tests are designed to process the relevant live input in your browser. Only grant hardware permissions when you want to run the corresponding test.
Frequently asked questions
Do I need to install software?
No. These tools are designed to work directly in a compatible web browser.
Why does the microphone or webcam ask for permission?
Modern browsers require permission before a website can access your microphone or camera.
Can these tools prove that hardware is physically damaged?
No. They can show whether your browser receives expected input or display information, but they cannot diagnose every hardware, driver or operating-system problem.
