CS-Cart
CS-Cart is highly customizable software, it provides full access to the source code, and there are no encrypted files in it. Thanks to this it is possible to make any changes, integrations and modifications according to the users specific needs. CS-Cart is built using PHP and MySQL, AJAX technologies are utilized as well. Design architecture of CS-Cart is based on Smarty template engine that, along with completely CSS-based template layout, makes it very simple to change the look-and-feel of the storefront. Apart from a bundle of features and add-ons, included into the software by default, there are many add-ons and themes, created by third-party developers, which are listed in CS-Cart Marketplace (http://marketplace.cs-cart.com/)
