1) Zen cart
URL: http://www.zencart.com
Language: PHP
Features:
In terms of features and large community support , zen cart is the best open source shopping cart. It is also based on Oscommerce, an open source shopping cart writen in March 2000.
- multiple customer modes
- multiple sales and discounts
- multiple ad banner controller
- multiple shipping options/modules
- newsletter manager
- gift certificates
The one complaint I have with all of the oscommerce-based shopping carts is the lack of a proper template and module system. Because module code is not separated from template/cart code, when there are security updates, you need to manually make these changes.
2) Magento
URL: http://www.magentocommerce.com
Language: PHP
Features:
- Multi-language support
- Built-in API for easy integration with 3rd-party services
- Auto-generated Site Map
- Newsletter Management
- One-Page Checkout
- Create one or multiple invoices, shipments and credit memos per order to allow for split fulfillment
Magento is a great shopping cart. However, it doesn’t have as large of a community (or as many user contributions/modules) as some of other open source e-commerce solutions.
