Wagtail is built by developers for developers. It is an open source content managing system built on the Django framework. It provides a fast and attractive adminitrator interface for editors and publishers.
Wagtail is one of the best CMS available. We have been using Wagtail in production for two years and we are very happy with it. From a technology point of view, it puts the programmer in control of a modern MVC platform that is designed to get the job done without problems.
