Our TYPO3 Technology Stacks

Domain-Driven Design (DDD)

Our approach revolves around aligning software design with the specific business domain, resulting in TYPO3 solutions finely tuned to the unique needs of our clients.

MVC Model

We adhere to the Model-View-Controller architecture, promoting maintainability and organisation within TYPO3 extensions. This structured approach simplifies expansion of TYPO3 solutions.


TYPO3 Core primarily consists of the API (Application Programming Interface), which defines a framework for managing the project content.

Extbase Framework

The Extbase framework simplifies TER extension development, guiding developers in adhering to the Model-View-Controller (MVC) by following this core framework.

Fluid Rendering

Fluid, TYPO3's templating engine, is a vital component for rendering dynamic content within TYPO3 extensions. It provides a flexible way to create templates that align with modern web design practices.


These configuration tools are vital in effectively configuring and customizing TYPO3 TER solutions without touching to the core of TER extensions.

Frontend Tech-Stack

Our frontend technology stack encompasses HTML5, CSS3, Vanilla JavaScript, and TypeScript, allowing us to create modern and responsive TYPO3 solutions that enhance user experience.

Community-Made TYPO3 Extensions refers to TYPO3 Extension Repository(TER). It is also called TER. Extending refers to extending and modifying TYPO3 extensions to meet specific project requirements. It involves making adjustments to existing third-party TYPO3 extensions to increase TYPO3 functionality.

Extending Community-Made TYPO3 Extensions allows you to come up with additional feature requests, improved integration, or specific design changes; developing is like customisation, ensuring that the extension aligns perfectly with your objectives.

Almost any TYPO3 extension available at the TYPO3 Extension Repository can be customised through this service. This includes extensions related to content management, e-commerce, SEO, forms, and more.

The timeline for extending varies depending on the complexity of the project and the specific requirements.  A detailed project assessment will provide a more accurate estimate, but it will still not take more than a few days.

Extending a TYPO3 Extension involves modifying existing extensions available at the TYPO3 Extension Repository while creating an extension from scratch, which means developing an entirely new extension. Extending is often more cost-effective and time-efficient when the base extension partially meets your requirements.

Customised extensions may require additional work to remain compatible with TYPO3 updates. Discussing long-term maintenance and updates with your TYPO3 developer to ensure smooth compatibility is essential.

TER Customization can be cost-effective when the base extension shares a significant portion of the desired functionality. Developing a new extension from scratch can be more time-consuming and expensive.

Look for a TYPO3 developer with a proven track record in customisation projects, expertise in TYPO3 best practices, and a willingness to understand your unique project needs. Client testimonials and portfolio samples can provide valuable insights.

You can request changes or updates to a customised extension as your project evolves. It may cost additional. 

To begin the TER Customization process, purchase the plan or fill out the contact form. We will assess your project requirements, provide an estimate, and guide you through the customized TYPO3 solution. Or you can purchase according to your requirements.
