TYPO3 is a mature, stable, and secure platform that has been actively developed and improved for over ten years. Unlike many newer, less sophisticated CMS solutions, TYPO3 is a full-grown, enterprise CMS that has been widely adopted by companies of all sizes across the world, and is an established standard throughout many universities, governments and organizations.
In 1997, Kasper Skårhøj began developing TYPO3 from scratch. At the time, the term Content Management was still widely unheard of. Today there are many open source and proprietary CMS solutions on the market, but none come close to TYPO3 in terms of sheer functionality and maturity. After more than ten years of active, incremental development, TYPO3 is effectively feature-complete, making it an extremely compelling solution for web content management.
TYPO3 was founded on the belief that true open source, community-oriented development can make tools that surpass proprietary solutions. It is free and open to everyone, yet powerful enough for mission-critical commercial use. TYPO3 is an ever-expanding open source project that draws its strength from the imagination and ingenuity of those who use it. You do not have to pay a licensing fee for TYPO3 and you never will—leading to significantly reduced total cost of ownership (TCO) in both the short and long-term.
