1-Click Installation of Joomla!

Joomla! is an award-winning content management system (CMS) that enables the creation of websites and powerful online applications.

You can set up Joomla! at IONOS quickly and free of charge using a 1-click installation through the App Center.

Advantages of 1-click installation:
  • Simplified installation process
  • No need to upload and download installation packages
  • You will receive the latest Joomla! version

Afterwards, you can customize your installation according to your needs and extend it with plugins and themes without any restrictions.

Please Note

The 1-click installation is only available for installing websites based on Joomla! 4. If you want to create a website based on Joomla! 3, you can download the installation package separately from https://downloads.joomla.org/latest and install it manually in your webspace.


For the 1-click installation of Joomla! you need the following:

  • A Linux hosting package or a Managed Dedicated Server
  • An available domain or subdomain
  • An available MySQL/MariaDB database

  • Open the App Center by clicking the button below. If you have multiple web hosting plans, select the plan where you want to install Joomla!
