Hey Everyone, On Sunday I was contacted by a client and they said the needed a shopping cart up by Monday. Since they needed this cart up so fast I went to the easiest solution I knew, Open Source Shopping Carts. I browsed through tons of shopping carts and put together a list of only the best carts. The list is below.

is robust, professional grade e-Commerce shopping cart that you can download, install, and use for free. In the back end, you will use a full featured back end to manage your inventory, orders, shipping, and customers in real time. Your customer’s payments are sent directly to your commercial bank account using the latest security technology. You can even add your own modules to the shopping cart.

is an open source PHP based online shopping cart system. OpenCart is easy to use and is SEO optimized with a very nice interface. A great feature of OpenCart is that customers can write their own reviews of the products.

is a professional open-source e-Commerce solution offering unprecedented flexibility and control. Magento is awesome, I would never believe it is an open-source project. It features clean urls and SEO from the start. Everything is designed in a clean and simple way. Magento also features: Unlimited flexibility, Completely Scalable Architecture, Professional and Community Support, and Smooth Integration with 3rd party apps.

is very popular shopping cart. CubeCart V3 is free, with the exception that you leave their copyright notice in your footer. CubeCart has a large amount of payment gateways and shipping gateways. Their support forums are lively and many people contribute plugins to the cart. To use CubeCart V4 you must pay but it has many features that V3 doesn’t have.

is another very popular online shopping cart, written in Perl/MySQL. It features a css manager so you can edit the look of your cart online. AgoraCart also features unlimited product options, up to 4 different tax zones at the same time, tons of shipping and payment gateways/options. The setup options range from a simple template based store to the integration of a complex visual design and support for program modification.
