Kepler is a free software
project written in Lua that provides a portable, extensible website
development platform. Current stable release is Kepler 1.1.1, for Lua 5.1. Kepler works on Windows
and most variants of Unix
.
The platform was designed to work with a number of web serving environments, called "launchers" in Kepler terminology. Kepler includes launchers for Apache
(mod lua), FastCGI
, CGI
, ISAPI as well as a native web server
written in pure Lua, called Xavante http://www.keplerproject.org/xavante/.
