Enterprise open-source CMS with TYPO3
TYPO3 is a battle-tested enterprise CMS trusted by governments, universities and global brands — built for complex sites, strict permissions, multilingual delivery and long-term ownership without vendor lock-in. We know how often the public sector chooses TYPO3, and we treat security, GDPR and institutional requirements as non-negotiable.
DIA Verde brings an experienced TYPO3 development team: new builds, extensions, performance work, and controlled migrations from older versions to the latest LTS — plus practical AI tooling for editors.
Why TYPO3 is a strong choice for serious websites
Unlike lightweight blogging tools, TYPO3 is designed for large information architectures, multi-site setups and editorial governance. You get enterprise depth with open-source economics and a predictable Long-Term Support lifecycle.
See if TYPO3 fitsEnterprise governance
Granular backend permissions, workspaces and approval workflows so marketing, legal and IT can collaborate without stepping on each other.
True multilingual CMS
Native multi-language and multi-site capabilities — ideal for EU organisations that publish in several languages from one installation.
Open source, no lock-in
You own the platform. No per-seat CMS tax for core features — invest in delivery, hosting and extensions that create real business value.
Predictable LTS roadmap
Clear release cycles with years of free security and bugfix support per LTS version — easier budgeting than unpredictable SaaS churn.
Security & compliance
Hardened setups, controlled access and GDPR-aware architectures — the baseline we apply for government and regulated organisations, not an optional add-on.
Extensible ecosystem
Thousands of extensions plus custom PHP development — integrate CRM, DAM, search, forms, AI and headless frontends when you need them.
Built for government and public institutions
We know TYPO3 is widely used in government agencies, municipalities, universities and public companies — environments where trust, accountability and data protection matter more than flashy demos.
DIA Verde takes that context seriously: security hardening, GDPR and privacy-by-design, accessibility, audit-friendly permissions and documentation your IT and compliance teams can stand behind.
Discuss a public-sector projectSecurity as a discipline
Secure configuration, least-privilege access, patch discipline and hosting patterns aligned with how public organisations actually operate — not "secure enough for a brochure site".
GDPR & privacy
Consent flows, data minimisation, cookie and tracking control, retention-aware forms and clear processor boundaries — designed for EU public-sector expectations from day one.
Governance & accountability
Role-based backend access, workspaces and approval paths so legal, communications and IT keep clear ownership of what goes live — with an audit trail when you need it.
Accessibility & inclusion
Public websites must serve everyone. We build with accessibility in mind — semantic structure, keyboard use and content patterns that support institutional standards.
Procurement-ready delivery
Clear scopes, documentation, handover and maintainable open-source stacks — so projects survive vendor changes, audits and multi-year budget cycles.
Sovereign control
Self-hosted or EU-hosted options, no forced SaaS lock-in for core content — your institution keeps control of data, infrastructure choices and long-term costs.
An experienced TYPO3 development team
TYPO3 rewards specialists. Our developers work day-to-day with TypoScript, Fluid, Extbase, Composer-based installations and modern frontend stacks — so you get maintainable code, not fragile one-off hacks.
Meet the teamDeep platform expertise
Backend architecture, custom extensions, TCA modelling, site packages and editor UX — the full stack of professional TYPO3 delivery.
Frontends that perform
From classic Fluid templates to headless Next.js frontends consuming TYPO3 content — we optimise for Core Web Vitals and editorial speed.
Partners who stay
After launch we support upgrades, security patches, extension maintenance and feature iterations — so your CMS stays healthy for years.
Need a TYPO3 team that already knows enterprise DXP patterns? We also work with Sitecore and Uniform — so when your roadmap spans more than one platform, you keep a single delivery partner.
Migrate from older versions to the latest LTS
Running TYPO3 7, 8, 9, 10, 11 or 12? Outdated cores mean security risk, incompatible extensions and rising hosting costs. We plan and execute upgrades to the current LTS with content preserved, SEO redirects in place and editors trained on the new backend.

Inventory of core version, PHP, extensions, custom code, TypoScript and hosting constraints.
Roadmap
Step-by-step upgrade path (direct or via intermediate LTS) with risk, cost and timeline.
Migrate
Composer updates, extension replacements, data & media migration, automated tests where possible.
Stabilise
Performance tuning, editor training, monitoring and a clear post-go-live support plan.
Legacy → modern
From classic installations to Composer-based projects with clean site packages and maintainable extension structure.
Zero-drama cutover
Staging environments, content freeze windows, rollback plans and URL mapping so go-live is controlled — not a leap of faith.
ELTS vs upgrade
Need more time? We help you weigh paid Extended LTS against a full upgrade so budget and risk stay aligned.
Yes — TYPO3 can work with AI
TYPO3 does not ship a closed "AI CMS" inside the core. Instead, the ecosystem connects your preferred LLMs through extensions and clean interfaces — so editors get assistance while you keep control of data, permissions and compliance.
We integrate proven AI tooling (content drafting, SEO metadata, translations, alt text, image analysis) into existing TYPO3 workflows — with human review, workspaces and role-based access still in charge.
Explore TYPO3 + AIEditorial copilot
Draft, rewrite, shorten or expand content inside the backend — faster publishing without abandoning your brand voice.
SEO & metadata
Generate meta titles, descriptions and structured hints at scale — then editors approve before anything goes live.
Translation & media
Accelerate multilingual sites and accessibility with AI-assisted translation and automatic alt-text suggestions.

How we deliver TYPO3 projects
Business before widgets
We start from content model, permissions and channels — then choose extensions and architecture that match your organisation, not a demo theme.
Upgrade-safe engineering
Composer, clean site packages and documented custom code so the next LTS upgrade is a project — not a rewrite.
Editors first
Backend UX, training and AI assistance that make day-to-day publishing faster — because adoption is what makes CMS investment pay off.
