Specs
Pros
Pro Great separation between developers and editors
Wagtail has the perfect separation between developers and editors. It allows you to construct a site with minimal fuss with features like the awesome stream field and hand it over to virtually any content editor. You can build the site with no knowledge of Django and with the simple interface require no training to get started.
Although this will always require developer time, with 2 or 3 days you can quickly get up a boilerplate site that will fulfill 80% of any site you will develop. Leaving only the bespoke parts to do.
It also nicely slots into any Django project with no fuss.
Cons
Con You need to be experienced in Django to get the most of it
Installing Wagtail on a remote server is a little more complicated than FTPing a bunch of files. Furthermore there's no ecosystem for plugins and themes so it can only be fully extended by a developer experienced with Django.
