Twelve extensions for TYPO3 CMS: content elements, a slug manager, a portfolio plugin, icon fields and AI tooling. Published in the TER, maintained on GitHub, installable with Composer.
Overview
Every extension, in one place
Everything below is written and maintained by KohlerCode. Nine are published in the official TYPO3 Extension Repository, all of them live on GitHub, and each installs with Composer. The download counts are the TER counters of 24 October 2026.
The list is ordered by downloads. Alpha means the extension is in active development, stable means it runs in production sites. Textile now sits in the TER abandoned pool and Modals stops at TYPO3 10; the rest are current.
