Wagtail

Wagtail is an open‑source content management system built on Django and Python. It provides a fast, attractive editing interface while giving developers full control over front‑end design and site structure. The platform includes features such as StreamField for flexible content modeling, integrated search powered by Elasticsearch or PostgreSQL, and a content API that enables headless deployments. It supports multi‑site, multi‑language publishing and can run on a wide range of environments from a Raspberry Pi to large cloud infrastructures.

The system is aimed at teams that need a highly customizable CMS—designers can define precise templates, editors can compose rich pages without code, and developers can extend functionality with ordinary Django code. Its architecture is cache‑friendly and scales to millions of pages and thousands of contributors, making it suitable for both small projects and enterprise‑level sites.

Wagtail is released under the BSD‑3‑Clause license, requires no subscription, and is maintained by a strong community with commercial support. It is used by organisations such as NASA, Google, the NHS, Mozilla, MIT, and various government and cultural institutions.
