There is a ton of Languages for erlangs BEAM,

My favorite: Joxa a Clojure inspired (really just inspired ;)) lisp http://joxa.org/

Then there are Elixir (mentioned already) and Reia, Both seem to be inspired by Ruby. http://reia-lang.org/ http://elixir-lang.org/

Erlang has a far superior computational model an implementation than Node, it can handle way more requests faster and is newcomer friendlier as any web request is simply a message received.
