Comprehensive Device Testing Suite
IObit Online Device Tester provides a complete suite of diagnostic tools to test and verify your hardware components. From keyboard and mouse input to microphone, webcam, screen, CPU, network, and more, most tests run in your browser without installation. Network speed and health tests exchange test data with Worker endpoints, while sensitive device access requires browser permission and is not intentionally stored by this service.
Whether you're troubleshooting hardware issues, verifying device functionality, or benchmarking performance, these testing tools can help you narrow down a problem. Tests generally run in your browser; network speed and health tests necessarily exchange test data with Worker endpoints. Browser tests cannot conclusively diagnose every hardware fault.

How to use these browser tests
Choose the tester that matches the device or browser feature you want to check, then follow the prompts in the live test area. If the tool asks for camera, microphone, location, or clipboard access, approve only the permission needed for that specific test.
What results mean
A successful result means the current browser can access or measure that feature with the current settings. A failed result may still be caused by browser permissions, extensions, drivers, operating-system privacy settings, or network conditions rather than broken hardware.
Before assuming hardware failure
Repeat the test in another browser, check site permissions, reconnect external devices, and compare results on another network or device when possible. Browser-based diagnostics help narrow down issues but cannot replace professional repair or manufacturer support.
General FAQ
Do I need to install anything?
No. The tests are designed to run in a modern browser. Some tests require browser permission because they access device capabilities such as a microphone, camera, or location.
Are camera or microphone recordings stored?
Camera and microphone tests depend on browser permission and are not intentionally stored by this service. Network speed and quality tests exchange test data with Worker endpoints to measure the connection.
Can these tools confirm a device is broken?
They can show whether a feature responds in the current browser, but results can be affected by permissions, extensions, drivers, and operating-system settings. Confirm important findings with another browser or professional support.
