osCommerce is an online shop e-commerce solution that offers a wide range of out-of-the-box features that allows online stores to be setup fairly quickly with ease, and is available for free as an Open Source based solution released under the GNU General Public License.

osCommerce was started in March 2000 and has since matured to a solution that is currently powering 11,888 registered live shops around the world.

Today, osCommerce has been taken to the next level, moving towards an e-commerce framework solution that not only remains easy to setup and maintain, but also making it easier for store administrators to present their stores to their customers with their own unique requirements.
