The Erlang Twist on Web Frameworks

Erlyweb is an open-source web application framework written in Erlang and released under the GPL. ErlyWeb was created by Yariv Sadan. It builds upon Yariv's earlier modules that he created for Erlang: Smerl (Simple Metaprogramming for Erlang), ErlyDB (a database abstraction layer for Erlang), and ErlTL (a templating language that compiles to Erlang).

The code is available at [Google Code].

Currently, several sites have been built using ErlyWeb:

• [BeerRiot] - a community site for reviewing beers.
• [Twoorl] - a twitter clone written in Erlang, released under the GPL.
• [Vimagi] - a community site for painting. Uses comet so that people can paint on the same canvas at the same time.
