LFE has many origins, depending upon whether you're looking at Lisp (and here), Erlang (and here), or LFE-proper. The LFE community of contributors embraces all of these and more.

A Modern Taste

Behind the Scenes at LFE.io

You will notice that this site has interesting background images; though blurred, you might be able to discern the original source...

We have the 1910 edition of Whitehead and Russell's Principia Mathematica, John McCarthy sipping from an LFE mug; a PDP-11; a Tektronix terminal displaying an LFE ring benchmark; a data center; a Raspberry Pi cluster. All of these relate to LFE either via a Lisp heritage or current work being done in the LFE, Erlang, or Lisp communities.

They are our past and our future ... all are interconnected.

The Ring Benchmark in LFE



Over the years there have been several LFE presentations given at conference and meetups. We have gathered them together here for your convenience and viewing pleasure.

LFE Github Org

Did you know there are two Github orgs (core & community) dedicated to LFE? You can find most LFE projects in the world either here as their main repo, or as a forked mirror.


LFE has a small but growing community consisting of language developers, hackers, and general enthusiasts with a wide variety of experience and backgrounds. At any given point on the mail list or IRC channel, you may find yourself conversing with Clojurists, Erlangers, Haskellers, Javaheads, Lispers, OCamlers, Pythonistas, Rubyists, Schemers, etc.

The unifying element?

A deep appreciation of the Erlang VM and a perverse love of parentheses.
