I don't really understand what is the name of the web server from meteor.js.

Because in PHP for example, by default, we are using ngix (or apache).

In python, we are using werkzeug (it's not really a web server in this case, but a library but the objective is similar).

In rails, we are using by default Puma.

But impossible to know what we're using in Meteor. We don't have a specific web server ? we are only using Meteor ? I know the fact that meteor is a client/server framework built on top of nodejs (on the server side), but i don't find more precise detail about the name or the type of web server.
