Kepler is an open source platform that brings the power of Lua to web development. There are a number of great Web development platforms out there but none balances portability, size, power and extensibility quite like Kepler does:
Being extremely portable and light means that it can be installed in very constrained devices as much as in providers that limit the amount of RAM and processing time for your scripts.
If you ever heard of the customization features of games such as World of Warcraft, think about all that power applied to web scripting.
Being extensible means both that we can extend the platform by adding new modules and that the users of the applications that you build can extend those applications using Lua.
Kepler was created by Fábrica Digital and PUC-Rio and is continuously being improved by a core team of commiters (see Dev Team) and lots of contributors (see Credits).
Kepler is free software and uses the MIT license model: it can be used for both academic and commercial purposes at absolutely no cost. See the Kepler License for more details.
Downloads
The Kepler 1.1 Unix installer can be downloaded from its downloads page. Check the Installation page for more details and for the Windows installation instructions (using LuaRocks).
If you need the binaries for specifics Modules you can also get them from LuaForge, on the module respective project page.
Features
Kepler is a platform that uses LuaRocks to offer Modules such as:
- Page based and MVC XHTML generation (WSAPI, CGILua and Orbit)
- SQL and XML processing (LuaSQL and LuaExpat)
- Hash (MD5) and a pair crypt/decrypt
- Zip files reading (LuaZip)
The Lua community is constantly contributing with more modules that can be used with the Kepler Architecture. Most of those modules are catalogued on LuaForge and new ones keep coming.
Requirements
Kepler requirements are few, it runs on Windows and most if not all kinds of Unix. This includes devices small as the NSLU2 or the Nokia N800. The Kepler installer assumes LuaRocks, but Kepler can be used without it too.
Status
The current version of Kepler is 1.1, check the Installation page to use it.
For more details about the development of the new versions you can check the Releases, Vision, Road Map or the Developers pages.
