Wagtail
Definition
Wagtail is a professional open source CMS built on the Django framework (Python). It powers demanding organisations like Google, NASA and the British NHS, and more than 60 French government websites.Wagtail is the CMS we have used at KernWeb since 2015. Unlike plugin-based CMSs, everything is developed to measure: every page template, every content block is designed for your project, in a clean, maintainable architecture.
Its strengths for a professional website: solid security (Django architecture, no pile of third-party extensions), a clear editing interface that teams master quickly, native multilingual designed in from the start, and real durability: a well-built Wagtail site evolves for years without a full rebuild (regular LTS releases, documented upgrade path).
Another fundamental difference with proprietary platforms: with a custom-developed Wagtail site, you own the code. No captive subscription, no platform that shuts down, no theme shared with your competitors.
It is the technology behind our Business and Premium packages: see our offers or the Wagtail vs WordPress comparison.
Wagtail is open source and widely adopted: you are never a supplier's prisoner. Any serious Python team can take over a well-built Wagtail site.
