In my 10+ years of experience as a web developer Wagtail is hands down the best CMS I've ever used or worked on. We've been using Wagtail in production for about a year in an organization with an annual budget of 4M. I thought winning over the content editors would be a challenge, instead they turned into huge advocates after the initial training. But to leverage its full potential you really need to agree with the philosophy behind the technology. I've read other Wagtail reviews with the complaint that editors "cannot update the HTML code". This is by design. The philosophy (named The Zen of Wagtail) is in my opinion the best part of the CMS. You can read the official details here (http://docs.wagtail.io/en/latest/getting_started/the_zen_of_wagtail.html). But to summarize: The CMS should get content out of an admin/editors head and into a database as effortlessly as possible, the designer should call the shots on how things look (with html/css), and the programmer should be using a programming language (not a user interface). That philosophy sounds basic: make things efficient for all roles involved. But it has lead to design decisions for how the CMS works that are just brilliant. From an editor standpoint it is a dream come true. Every entry screen is custom coded to accept the data they need to enter. Custom data entry screens means the editor can make fast work of the task. And the editors I work with all agree that they really like this kind of system. From a technology standpoint, this puts the programmer in control of a modern MVC platform that is designed to get stuff done quickly. And they get to use all the tools they're familiar with (git, python, database migrations, unit tests, etc). The way the custom entry screens for the editors are built produce two outcomes: 1. they are ridiculously easy to build and 2. they keep all the design files (html/css) in a place that lets the designers modify them with ease. (We have web designers that do layout work.) By recognizing the three roles and requiring them to work efficiently you get a race car of a CMS.

I really love the product. It makes support seem easy.

I can create a custom content management experience for each of our clients. It is fairly easy to create new fields in the code.
