Mission Statement

"To Jointly Innovate Excellent Free Software Enabling People to Communicate."

The TYPO3 Core Development Team endeavors to make TYPO3 the best of its breed. To achieve this mission it pursues the following goals:

  • maintain and enhance the TYPO3 core
  • ensure TYPO3 source code quality
  • be a pillar of the community

This translates into the following tasks:

  • package and publish new releases according to the release and maintenance policies
  • review patches both before and after commits
  • care for the central development infrastructure (version control system, bug tracker)
  • participate in the mailing lists and in community events, in particular the TYPO3 Developer Days (T3DD)
  • ensure its own continuity by educating and inspiring community members to participate in the development and maintenance of the core


  • Not all members take up all the tasks, but the whole team is responsible for that.
  • Members must keep an open mindset to new ideas from both inside and outside of the team.


Whether you have questions or comments about the development of TYPO3, want to contribute or join the team, just get in touch with us.

Instant communication platform (Slack)

The TYPO3 CMS team is using a tool called Slack kindly provided by to openly communicate with each other and with the public. "Slack" replaces our old "Skype meetings" in a more open, inviting and modern environment. The Slack tool is also used by plenty of other teams around the TYPO3 ecosphere so it is easier to interconnect teams.

Head over here to sign up (it's free, thanks to the awesome folks over at Slack HQ).

Then join and our channel #typo3-cms.

Team Leaders

In case you have further questions, feel free to contact the Core Team Leader Benni Mack or the Product Owner Mathias Schreiber.

Please understand that technical support requests will be ignored. You are kindly asked to use Slack instead.
