About

Signal Desk is a public beta that helps beginners and all ages check peripherals—keyboard, mouse, display, microphone, speaker, webcam, and gamepad—in the browser without installing software.

Device input, media, and checkup results stay in this browser; raw device data is not sent to a server. We separate browser observations from user confirmations and do not claim SSD SMART, RAM health, temperatures, or official certification that a browser alone cannot prove.

Some checks may remain unsupported, permission-denied, or skipped depending on the browser, permissions, and hardware. Results are observational reference only—not repair advice, warranty findings, or official certification.
