Private by design
Nothing you test is sent anywhere
Every measurement happens inside the page you are already on. The result appears on your screen and goes no further — there is nothing to upload, because nothing is collected.
- No recording, image or reading is uploaded
- No account, no sign-in, no tracking profile
- Camera and microphone open only when you press start

Sweep how often frames reach your screen on a gray field, and watch for the brightness flicker some FreeSync/G-Sync displays show. The measured rate is shown; browsers can’t confirm VRR.
Marching bars that step one pixel per frame reveal skipped frames as stutter or doubling — best judged with a phone camera photo.
Ishihara-style plates that hint at red-green color vision differences. A for-fun, non-medical screening that depends on your screen.
Cycle colors and moving patterns full-screen to help even out OLED image retention. May reduce mild retention; can’t fix permanent burn-in.
Flash rapidly cycling colors over a stuck pixel to try to revive it. Includes a seizure warning, safe speed limits and auto-stop.
Confirm JavaScript is enabled and check support for common modern language features, with troubleshooting if scripts are blocked.
List your cameras, microphones and speakers with enumerateDevices, revealing names only after permission. Updates on plug/unplug.
A live JSON view of all buttons and axes, with a local event-trace recording you can download for debugging.
