TYPO3 Multisite

Are you managing multiple websites? TYPO3 Multisite is a great tool for you! It lets you run several websites from one TYPO3 installation. Here’s why it's helpful:

  • Central Control: Manage all your sites from one place. Update content or design, and changes can be applied across all sites.
  • Save Time: No need to log in to different dashboards for each site. Do everything from one dashboard.
  • Shared Resources: Use the same TYPO3 Templates, extensions, and users across all sites. This keeps everything consistent and saves you from duplicate work.
  • Flexibility: Each site can still have its unique look and feel. Customize them as much as you need.
  • Cost-Effective: Managing multiple websites from a single installation with the TYPO3 AI Website Builder reduces hosting costs and simplifies maintenance.

TYPO3 Multisite makes managing multiple websites easier, saving you time and effort while keeping everything organized.

Multisite means running several websites in a single TYPO3 installation. Instead of maintaining a separate system for each brand, region or department, all presences share the core, extensions and user management but each have their own page trees, domains, designs and languages.

The advantage is less effort. Updates and security measures only have to be carried out once, extensions are available centrally, and content can be shared when needed. Costs for hosting and maintenance also fall because resources are used jointly.

Setup is done via site configurations. Each website receives a root page, base URL, languages and its own settings. With site sets and templates, designs and functions can be shaped differently. Editors receive access only to their areas.

Typical use cases are corporations with several brands, universities with faculties, associations with regional branches or companies with country sites. Shared building blocks such as contact data or legal texts can be maintained centrally and displayed everywhere.

Note limits: an error or outage affects all websites, and large installations need corresponding resources. Check whether a shared installation or separate systems fit better, for example with very different requirements or strict separation rules.

Plan the permission concept, naming conventions and responsibilities carefully so that teams do not disturb each other.

SEO aspects are also important: separate sitemaps, canonical tags and a clear domain structure prevent duplicate content.

Test updates first on staging, since they affect all presences.

We plan and operate multisite environments with TYPO3.

This keeps many websites centrally manageable.

In short: TYPO3 Multisite: Manage Multiple Websites Easily.
