Backed by the Swiss software development agency Divio, django CMS is one of the most active open-source projects in the Django ecosystem, and is used to powers tens of thousands of sites large and small across the world. django CMS is developer-friendly, readily extensible and integrates beautifully with existing Django apps. It's also easy-to-use for content editors who need to get started quickly. The community of django CMS developers is friendly and welcoming, and works hard to make the experience of participating in open source a positive one.
Come to DjangoCon US, and meet Martin Koistinen and Daniele Procida, two of the project's core developers.
