Cotonti combines the flexibility of a web framework with the rapid deployability and featureset of a content management system. Despite having features such as user accounts, content creation, file management and community tools out of the box, it can be easily extended using modules or plugins. Cotonti is powered by its own template engine which is both fast and easy to learn, even if you are not an experienced programmer.
