The bench

About Gear Checkup

Gear Checkup is a diagnostics bench in your browser: eight instruments that answer the only question that matters when hardware misbehaves — is it broken, or is it software? Every test runs locally using standard browser APIs. Nothing is uploaded, recorded or retained, which is also why the tests start instantly and need no account.

The verdicts are diagnostic aids written in plain language, not certified measurements. When a test says PASS, it means the device reports correctly to the browser in a clean environment — which localizes the vast majority of faults in one direction or the other.

Gear Checkup is made by Made Twenty.
