Magento includes multiple licence types, these include Magento Open Source, Magento Commerce and Magento Commerce Cloud. Magento Open Source is a free to use, open source licence meaning anyone can download, install and customise the platform for commercial use. Magento Commerce on the other hand is a paid for licence. Magento Commerce includes more functionality than the standard Magento Open Source package including for example Magento page builder, content staging and scheduling, more comprehensive visual merchandising capabilities and access to Magento’s technical support. Lastly, Magento Commerce Cloud is identical to Magento Commerce but instead of hosting it on you or your agencies web servers, they are hosted on Magento’s own cloud servers. Fundamentally, all of them are open source, giving you the complete freedom to customise.
