Device & Hardware Tests
Hardware you can check before you buy, before you return it, or before you blame the software. Every test runs live in this tab using the browser's own device APIs — press a key and watch it register, wiggle the stick and watch the drift, tilt the phone and watch the gyroscope move. Nothing is recorded and nothing is uploaded.

All 53 tools here are free and open immediately — there is no registration step, no credit card and no daily allowance to run out of. Most of them do their work in your browser, which means the page keeps working on a slow connection and your input is never sent to a server.
