Choose a focused device test for microphone input, webcam preview, controller buttons, keyboard keys, mouse buttons, or input timing.
All tools run in the browser and are built for quick checks before calls, games, streams, recordings, or desk setup changes.

Which device test should I use?
Use the microphone test before recording or joining a call, the webcam test before streaming or meetings, and the gamepad tester before playing with a controller. Keyboard and mouse tests are useful after changing devices, layouts, switches, USB hubs, or browser settings.
Why does a device test need permission?
Browsers require explicit permission for microphone and camera access. If a test is blocked, check the browser prompt, operating system privacy settings, and whether another app is already using the device.
