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 [1].


Kepler also provides the following frameworks:


Kepler also provides the following modules:

  • CGILua - tool for creating dynamic Web pages and manipulating input data from Web forms, providing a CGI-like programming paradigm for different launchers such as Xavante and mod_lua
  • LuaSQL - an interface from Lua to a DBMS, enabling Lua programs to connect to ODBC, ADO, Oracle, MySQL, SQLite and PostgreSQL databases
  • Copas - a coroutine-based dispatcher, used by Xavante
  • Cosmo - a templating engine that is "safe" protecting applications from arbitrary code within templates
  • Coxpcall - coroutine compatible encapsulation of native pcall and xpcall
  • LuaFileSystem - a library of file manipulation routines complementing Lua's basic set
  • Rings - a library for creating isolated Lua execution environments from within Lua
  • LuaExpat - an interface to the XML processing library Expat
  • LuaLogging - a simple logging API
  • LuaZip - library for reading inside ZIP files
  • MD5/DES56 - basic cryptographic library, providing a digest function and a crypt/decrypt pair
