No, it is built right on top of Erlang for seamless integration, and of note is that it was created by Robert Virding, one of the original creators of Erlang along with Joe Armstrong.

LFE macros deliver true homoiconicity to Erlang. It is a Lisp 2, and supports function and macro definitions at the REPL.

I prefer it to Elixir, because I prefer Lisp. Robert has also created a Lua 5.2 written in pure Erlang.

Evidently, Erlang's actors and BEAM VM were influenced by the JVM and Scala, so I guess doing a JVM Erjang was in the cards. [1]
