TYPO3 CMS Development The Enterprise CMS for Ambitious Web Projects
Municipalities, cantons, large enterprises — when accessibility, multilingual capabilities, and scalability aren't optional features but fundamental requirements, TYPO3 is the right choice. As an experienced TYPO3 agency, we've been delivering complex multi-site projects with the highest security and compliance standards for over 20 years.
The CMS that grows with your requirements — not one that hits its limits. Multi-site, multi-language, role-based workflows, enterprise security. Built for organisations. That means: granular permissions, versioned content, automated deployments.
While other CMS platforms struggle with ten language versions or a hundred editors, TYPO3 is just getting started. The system was designed from the ground up for the demands of large organisations — with native multilingual support, fine-grained access controls, and a workspace concept that enables clean editorial processes. At Sidora, we deploy TYPO3 specifically where scalability, compliance, and accessibility aren't buzzwords but daily reality.
Three pillars. One goal: TYPO3 as your central content platform.
We design TYPO3 installations that remain performant and maintainable even with dozens of websites, hundreds of editors, and millions of page views.
Multi-site management
Central management of dozens of websites in a single TYPO3 installation with shared templates, individual domains, and granular access control.
Multi-language with fallback chains
Native multilingual support with configurable language fallbacks, overlay mechanisms, and separate navigation structures per language.
Workspaces & staging environments
Editorial workflows with staging areas, approval processes, and preview functionality — without affecting the live system.
Custom content types with TCA
Tailored content elements and backend forms via the Table Configuration Array — flexible, extensible, and editor-friendly.
Structured backend layouts
Clear backend layouts for editors with well-defined content areas, drag-and-drop, and visual page preview.
From custom Extbase extensions to seamless integration with your business systems — we build what your project needs.
Extbase/Fluid extension development
Custom TYPO3 extensions following the MVC pattern with Extbase and Fluid — cleanly structured, testable, and maintainable.
REST API & headless CMS
TYPO3 as a headless backend with REST API for modern frontend frameworks like React, Vue.js, or Next.js.
ERP/CRM integrations (SAP, Abacus)
Seamless integration with your business systems: SAP, Abacus, Salesforce, Microsoft Dynamics, and more via standardised interfaces.
LDAP/SSO integration
Single sign-on and LDAP integration for seamless authentication against your Active Directory or identity provider.
Composer-based deployments
Modern deployment workflows with Composer, CI/CD pipelines, and automated releases for secure and reproducible deployments.
Older TYPO3 versions are a security risk. We migrate your installation to the latest release — without data loss, without downtime.
TYPO3 v8/v9/v10 → v13 upgrades
Structured migration of older TYPO3 versions to v13 LTS with comprehensive compatibility checks and automated upgrade wizards.
Relaunch of existing installations
Modernisation of existing TYPO3 websites with new design, current templates, and optimised content structure.
Data migration from legacy systems
Import and transformation of content from legacy systems like Drupal, Joomla, or proprietary CMS into TYPO3.
Performance optimisation
Analysis and optimisation of load times, database queries, caching strategies, and asset delivery for existing TYPO3 installations.
Technical debt reduction
Code audit, refactoring of outdated extensions, and cleanup of legacy issues for a future-proof TYPO3 foundation.
Your enterprise project deserves a CMS that unites security and scalability
Let's analyse together whether TYPO3 is the right platform for your requirements. In a no-obligation architecture consultation, we'll clarify your goals, evaluate complexity, and outline a realistic project framework.
From requirements analysis to go-live: Structured and transparent
Requirements Analysis
We analyse your existing infrastructure, define target audiences, language versions, and integration requirements. The result: a detailed specification that serves as the foundation for all subsequent steps.
Architecture & Concept
Based on the specification, we design the TYPO3 architecture: site structure, permission model, extension landscape, and deployment strategy. For multi-site projects, we define inheritance logic and language fallbacks.
Design & Prototyping
Our design team creates the user interface — accessible per WCAG 2.1 AA and optimised for all devices. Interactive prototypes enable early feedback before a single line of code is written.
Development & Integration
Fluid templates, Extbase extensions, backend configuration — our development team implements the architecture in a staging environment. Parallel code reviews and automated tests ensure quality.
Testing & QA
Functional tests, accessibility audit (WCAG), performance benchmarks, and security scans. Only when all criteria are met do we approve the deployment.
Go-Live & Training
After go-live, we train your editors in the TYPO3 backend. We create tailored documentation and stand ready during the hypercare phase for rapid adjustments.
Proactive protection for your TYPO3 investment
