Contao is content management system (CMS) for people who want a professional internet presence that is easy to maintain. The state-of-the-art structure of the system offers a high security standard and allows you to develop search engine friendly websites that are also accessible for people with disabilities. Furthermore, the system can be expanded flexibly and inexpensively. Easy management of user rights, the Live Update Service, the modern CSS framework and many already integrated modules (news, calendar, forms, etc.) have quickly made Contao one of the most popular open source content management systems on the market.
Contao has an intuitive user interface that uses Ajax and Web 2.0 technologies for optimal usability. Multiple back end languages and themes, a powerful permission system, versioning and undo management, advanced search and sorting options or the Live Update Service are just a few of many features that make Contao stand out from other CMS. The Contao front end is 100% template based and generates accessible XHTML strict output that meets the W3C/WAI requirements. Search engine friendly URLs, GZip support, a PDF export function, multi-language support and many more allow you to build contemporary websites without being a programmer.
