How to Check if Your Devices Work
Buying a new laptop, joining a video call, or troubleshooting a flaky peripheral — there are plenty of moments you need to confirm your hardware actually works. Our four browser-based tools let you do that in seconds, without installing anything or granting access to a third party's servers.
Use the keyboard testerto make sure every key registers, the webcam testbefore your next meeting, the microphone testto check your mic level, and the screen testto hunt down dead pixels on a new monitor. Each tool runs entirely in your browser — your camera feed, audio, and keystrokes never leave your device.
