At the end of April 2026, free support for TYPO3 version 12.4 will expire.
It’s high time to start thinking about an upgrade to TYPO3 13.4 — depending on the number of (custom) extensions in use, the effort required for this upgrade can be considerable.Upgrading to TYPO3 13.4 provides a support-free horizon until December 2027 — a period that allows you to focus on what really matters: continuously optimizing your website’s features and content to best meet the needs of your target audiences.

As TYPO3 experts with the experience of more than 10 upgrades to TYPO3 13 this year alone, we analyze your site and carry out the upgrade on time and with long-term stability in mind.
If needed, we’re also available as a reliable partner for ongoing maintenance and support.
Get in touch with us —we’ll be happy to prepare a tailored offer for you.

Students and teachers are the core audiences of the Klassik Stiftung Weimar’s (KSW) educational offerings.
Last year, we developed the UX concept for a new education portal — a platform designed to meet the specific needs of these target groups in a focused, practical way.

Now, we’ve been awarded the contract to design the new portal and, together with the foundation, create a contemporary, user-centered digital experience that makes access to Weimar’s cultural heritage intuitive and inspiring for young audiences.

Innohub is leading the Scrum process and implementing the new website in TYPO3.

We are delighted to be able to support Ulm University of Technology on its journey towards a sustainable and bold digital presence!

With over 10,000 students, Ostfalia is one of the largest universities of applied sciences in Lower Saxony. As part of a comprehensive relaunch, the entire website was redesigned and aligned with the needs and usage habits of its key target audiences.

The Accessibility Strengthening Act (BFSG) will come into effect at the end of June- many websites are still not fully prepared for the requirements of accessibility.
cosmoblone has gained a lot of experience in creating accessible websites over the last few years. In order to support operators of existing websites in their further development towards accessibility, we offer you the Accessibility Quickcheck.

The Quickcheck gives you an initial concrete overview of the accessibility status of your website. It shows which serious barriers exist and makes suggestions as to how they can be remedied before legal or economic risks arise.

In order to provide teachers, pupils and specialist audiences with better access to the Klassik Stiftung Weimar's on-site offers and online materials, we were commissioned by the foundation to design a new educational portal and a tool for requesting individually customizable multi-day excursion requests.

The website and database are to be handed over to an international partner at the end of 2025. We are delighted to have been awarded the contract to keep both (security) technology up to date until then and to hand them over to the new operator in documented form.

The International Climate Initiative (IKI) is an internationally oriented funding instrument of the German government, under which projects in the field of climate protection and biodiversity conservation are selected for funding through ideas competitions.

The aim of the current tender was to develop a replacement for the previous system for submitting application forms on an open source basis.

Based on the Open OAP extension for TYPO3 developed by cosmoblonde, we have designed and implemented a solution that, among other things.

• provides various forms for project funding that can be flexibly edited
• validates that only forms with the specified criteria can be submitted
• maintains a database for evaluation with an export option to other systems
• and users to set up an account to manage their project ideas at different stages

In addition to a user-oriented front end, the system has a back end that allows administrators to create forms and process and store data from submitted applications

The International Climate Initiative (IKI) is a funding instrument of the German Federal Government under which projects in the field of climate protection and biodiversity conservation are selected for funding through ideas competitions. The current system for submitting and processing project ideas is outdated and is to be replaced by a new one.

Im Auftrag der ZUG, einem Dienstleistungsunternehmen des Bundes, dessen Kerngeschäft Projektträgerschaften für Förderprogramme der Bundesressorts sind, soll nun ein neues Open Source basiertes System entwickelt werden, über das interessierte Organisationen mittels einem Online-Formular-Prozesses Projektideen bei der IKI einreichen können. Zusätzlich zu einem nutzerorientierten Frontend soll das System über ein Backend verfügen, das den Administrator*innen das Anlegen von Formularen sowie eine Datenverarbeitung und -speicherung der eingereichten Anträge ermöglicht.

We are very pleased to be able to adapt this system based on our TYPO3 solution for online application processes "Open Application Plattform" in an agile process, extended by complex form functions, optimally to the requirements of the International Climate Initiative and its applicants.

When creating the museen-in-bayern.de website, barrier-free accessibility of the website and its content was a key requirement from the outset. We are therefore all the more pleased that the website has now passed the official BIK test.
