Archviz Server hosting

Hello,
I have come across many tutorials to host a multi player game on your PC and people can access it to play the game together in the same instance.

But I am looking for a solution where, I can setup and host an archviz project on my PC and access it through browser from another PC / laptop/ipad to showcase the demo project to clients. Cause hosting on 3rd party clients/services comes with a cost, i currently need to do it for free.

What’s the best and easiest solution?
Thank you
