Why Use Browser-Based Hardware Tests?
Traditional hardware diagnostics require installing dedicated software, often from the peripheral manufacturer itself. These tools may work well for one brand of keyboard but not another, and many are only available on Windows. Browser-based testing removes those barriers entirely — the same test works whether you are on a MacBook, a Chromebook, or a Windows PC.
Our tools use standard Web APIs that modern browsers expose: the Gamepad API for controller input, the Web Audio API for speaker and microphone tests, Pointer Events for mouse diagnostics, and KeyboardEvent for key registration checks. These APIs give us direct access to hardware input without requiring elevated system permissions or driver-level access.
Because everything runs locally, your test data never leaves your device. There are no accounts to create and no diagnostic results stored on our servers. If you want to share results with a manufacturer or repair technician, you can take a screenshot directly from the tool.
No Installation Required
Open any tool and start testing in seconds. No downloads, no drivers, no browser extensions needed.
Works on Any OS
Chrome, Firefox, Edge, and Safari on Windows, macOS, Linux, Android, and iOS are all supported.
Private by Design
All diagnostics run client-side. No keystrokes, audio, or peripheral data is ever sent to our servers.
