Previously known as Magento Community Edition, Magento Open Source is the ecommerce platform. Adobe which acquired Magento in 2018 has confirmed the open source edition will remain part of their plans going forward. In web development open source means that software can be used on almost any platform and can easily updated, changed and redistributed as required. When you choose the open source option you will have the freedom to update and extend your store system without going back to the original developers.
