Can local server of MakeCode be used in a LAN?

Hi!
We have internet issues in class, so I tried the offline version of MakeCode, the offline version doesn’t support webusb, so we can’t upload directly to microbit.
I saw in https://github.com/Microsoft/pxt-microbit that I can setup a local server, however it states that “The local server lets you to run the editor and serve the documentation from your own computer. It is meant for a single developer used and not designed to serve the editor to a large amount of users.”
Is the local server available to just the machine it runs on, or can 10-20 users in a LAN use the it?
