# Measure a browser you are not sitting at

The ordinary flow assumes a person in front of the browser being measured: a click and a short pointer task. The browser you actually want to check is usually headless on another machine. This gives you a one-time address to open with it, and it is the one path here that does ask you to agree, because you are handing over a browser you are not sitting at.

Measure a browser I am not sitting at

The reading is taken on the machine that opens the address, not on this one, and it is stored under a one-time token so you can read it here. Layer 4, how a hand moves and types, will be missing, because there is no hand.

## What this one page cannot tell you

How that browser is operated. Layer 4 measures a hand moving and typing, and there is no hand, so it is reported as not available with the reason 'this needs your hand on the device'. Calling it a gap of the browser would be wrong: the same browser would produce it if someone were sitting there.

The interesting part is usually not a single value but the disagreement between two. [The full check](https://scalebrowser.net/check) reads all five layers and shows you where they contradict each other.
