TYPO3 is an enterprise-class, open source CMS, used internationally to build and manage websites of all types, from small sites for non-profits to multilingual enterprise solutions for large corporations.
The API-driven extension framework offers unlimited flexibility by letting developers extend the functionality and add new types of content elements using standard programming practices like MVC (model-view-controller) design. Thanks to the large community of developers that use TYPO3, you can already find a solution for almost any need in the Extension Repository.
TYPO3 is a user-friendly, intuitive tool for producing and maintaining web pages with just a few clicks of the mouse. Authors benefit from the full-featured rich-text editor that offers all of the formatting options they would need in a WYSIWYG (What You See Is What You Get) tool with a familiar word processor-like interface. Seamless integration of multimedia content and dynamic image manipulation are available to right out of the box in TYPO3. In addition, an internal messaging and workflow system helps content creators and editors collaborate in the administration backend.
TYPO3 provides an extremely detailed permissions system for implementing professional editing workflows for both users and groups. Administrators can even manage multiple websites in one TYPO3 installation and share users, extensions, and content between them.
Appreciate the complete separation of design from content that TYPO3 offers as a total CMS. The designer-friendly template system lets developers quickly and easily map existing HTML & CSS files to dynamic content without limiting the design options for professional website designers. If the website needs to change dramatically, site redesigns are easily implemented in TYPO3.
The extension framework and database-driven design of TYPO3 means that sites can scale easily and adapt to future needs without a large investment in hardware or costly rebuilds.
