Saas = software as a service, i.e. you have to pay recurring fees to continue using the website builder and keep your website online. It is a business model. Not all website builders are built on the SaaS model though. For example, open source platforms like WordPress, Joomla, or Magento, or my favorute website builder UltimateWB.
