Website builders belong to the family of content management systems (CMS), meaning a website builder is a form of a CMS. However, the main difference is that with a website builder, you get everything in one place – the editor, hosting, domain (if you like), security, and feature updates are provided to you by the website builder provider. Wix and Squarespace are two of the most popular website builders, although there are many excellent website builders that serve a wide range of needs.
If you use a CMS like WordPress, you’ll need to organize a hosting provider and domain yourself, and install plugins and updates manually. You also won’t get the same flexible visual editor you get with a website builder, which may make editing your site slightly more complicated.
