Its purpose is to enable the user to make a site quickly by using widgets and layouts. It allows you to assign permissions to every piece of content. These permissions can control such things as viewing and deleting the content.

Nitro is a really easy to use, very customizable, and extensible ORM for CodeIgniter. It's pure PHP, which means you won't have to install any commandline tools to run it, just one mapping file (or as many as you like), which is as simple as defining a PHP array, and let Nitro create the classes and manage the relations.
flexi cart is a shopping cart library for CodeIgniter. While CodeIgniter comes with its own cart library, the library is quite basic in functionality and is only aimed at creating simple e-commerce stores. The flexi cart library includes the following features: shipping, taxes, localisation, discounts and reward points/vouchers, multiple currencies, item stock control, surcharges, saving/loading of incomplete carts for later shopping, multilingual custom status and error messages, and currency and weight conversion tools.
Tinypug is a system for building portals that enables innovation communities. The idea is to go beyond one-off statistical surveys (which tend to only verify an existing paradigm) to foster real collaboration and anecdotal feedback from users/customers. A company seeking to gather more feedback on its products usually has to resort to a few existing stand-alone mechanisms such as polls and comments on product listings. But Tinypug puts all of these tools together in one place. It also makes it easier to integrate with call center applications for the active gathering of customer feedback. It's not a content management system as much as it is a feedback management system. It provides in-browser message boards, polls, surveys, and user-submitted ideas with voting. There's also a basic content system that enables you to upload and publish pages and images. You can customize the look of the site using themes and extend its functionality using add-on libraries.
