OpenCart is an Open Source store management system based on PHP and MySQL.
OpenCart was developed in the late 90s by Christopher G. Mann. The first versions were developed in Perl. The project stalled in the early 2000s to later be revived in 2005 by UK-based Daniel Kerr. He used the system as a base and developed a new version using PHP.
OpenCart has since then gone through major updates. Today it is a very well established e-commerce system with a large and very active community. The domain opencart.com is the center for downloads, support and also the marketplace for extensions.
