The (open) source of our strength

TYPO3’s commitment to open source is essential to our product. Our open source, professional CMS gives you the flexibility to plan for the future, add functionality, and rely on our top-notch security. As citizens of the broader open source community, we collaborate and give back to other products and groups, to strengthen our own software. By joining our community as a user or contributor, you help strengthen TYPO3, too. 

You benefit from TYPO3's open source ethos

TYPO3 is continually reinvented by an open source community. Our CMS puts the principles of open source into action for a reliable, secure, and innovative digital experience.

Stay open and flexible with TYPO3

Entering long-term contracts can burden companies with stress and unnecessary costs. TYPO3's use of open source licenses, tools, frameworks, and languages like Symfony, Composer, and PHP encourages customization that fully meets your needs — with no vendor lock-in. Our commitment to open source means that you can adapt to changes flexibly and choose the best software integrations for your product.

Committed and consistent maintenance cycles

You need to be able to count on your open source CMS in the long-term. TYPO3 offers regular release and maintenance cycles, so you can rely on our product and know when it’s time to update to the latest version. Regular maintenance, priority bug fixes, and three years of optional, extended long term support (ELTS) make for predictable cost and timeline planning.

Active citizenship within the Open Source Community

The open source ethos is about giving back as much as you take. We believe that open source products are made stronger by willing and enthusiastic contributions. To give back, we support and promote other open source products and technology partners, contribute to PHP standards, and participate in the CMS Garden community. We also collaborate on security issues with other open source CMS platforms, including Eco, Joomla, and Drupal.
