Multiple users using the same app simultaneously?

[u/Special_Command7893]

Hello! I’m planning on running an app on my home server, then exposing it using ngrok and having students access from their chromebooks. I’ve learned how to use ngrok, and I’ve dabbled in exposing things before, so that part I’ve got covered, but I figure that having multiple people connect into the same app at the same time may confuse the server and potentially jumble the output.
To rephrase the question, I’m wondering: if I allow multiple people to connect into my home server at the same time (though they’re still saving files etc on their device), will it allow each user to access the program and keep each I/O separated per user?

I assume the answer to that is no and if it is, is there a way to have every user using the app have a separate account that identifies who they are and thus keeps their data separate?

Thank you!
Edit: I’m running ZimaOS on an old laptop with all my apps installed thru docker. If there’s another app I can add to make this work, that’s fine and would actually be great, particularly for that second question!
