CodeRed CMS is a fairly new content management system that makes a Wagtail CMS ready go out of the box. It does require a little configuration, but not much compared to when creating a Wagtail site from scratch. However, if you get tired of CodeRed, you can always fallback to using Wagtail directly or even Django. It requires a little more effort than setting up a WordPress site (a WordPress site use to take more effort to set up than it used to).

The Streams editor in Wagtail is similar in concept to WordPresses new Gutenberg Editor. Wagtail's came first. The Streams editor lets you compose a page out of different kinds of content blocks and therefore the page is highly customizable.
