Server benchmark

This page times how fast input from this device reaches the engine and comes back. At a venue, run it twice: once on the venue's Wi-Fi and once on mobile data. The page keeps both and shows them side by side.

This run's network

The browser cannot tell, so pick it. With two devices, pick the network of the device that scans.

Nothing has run yet. Keep this page open and your device awake while it runs.

One run takes about 50 s. It opens no session: it uses two short-lived credentials made for it, good for one minute, and the page ends its run inside that minute. One address gets one run a minute. This browser keeps your last runs so two can be compared; nothing is uploaded.
