Show HN: Puter Beta – A Computer in Your Browser

I saw this on Product Hunt and checked it out today. I was impressed by how seamless the user experience was. Well done. Do you mind sharing the tech that was used to build this?

The name vaguely&#x2F;almost translates to &quot;Wh<i>re house&quot; (Puter</i>) in Spanish.

I find it amusing that I can play Doom :)
