At the Heart of Open Source: TYPO3.
TYPO3 is a professional, enterprise-grade CMS — and 100% open source. Everyone can use, study, modify, and share our software freely. It’s this openness that fosters innovation, longevity, dependability, and an active network of contributors.
The Power of Open Collaboration
TYPO3’s strength comes from its community. Developers, agencies, and organizations continuously improve the software, ensuring it stays secure, stable, and adaptable. By joining the TYPO3 community, you directly shape the CMS and benefit from shared expertise.
Open Source Benefits
TYPO3 is built on open technologies like PHP, Symfony, and Composer. You can integrate, extend, and customize your system without vendor lock-in or restrictive contracts. Our transparent Open Source Licenses ensure your full control and compliance.
Predictable release cycles, continuous maintenance, and a dedicated security team make TYPO3 a dependable foundation for digital projects. Extended Long Term Support (ELTS) provides stability for years to come.
