Magento is an open-source e-commerce platform written in PHP. The software was originally developed by Varien, Inc, a US private company headquartered in Culver City, California, with assistance from volunteers.
Varien published the first general-availability release of the software on March 31, 2008. Roy Rubin, the former CEO of Varien, later sold a share of the company to eBay, which eventually completely acquired and then sold the company to Permira; Permira later sold it to Adobe.
Magento provides two distinct platforms: Magento Open Source (previously Magento Community Edition) and Magento Commerce; the latter is available in an on-premises version (previously Magento Enterprise Edition) or as a platform-as-a-service (previously Magento Enterprise Cloud Edition). There were also two former platforms, Magento Professional Edition, and Magento Go.
