ThemeWare® Customizing App (Cloud)

In this article you will learn all about the free "ThemeWare® Customizing App".

Individual customizations have to be implemented in Shopware 6 with an own theme or an extension (plugin or app).

For the integration of individual customizations you may use an extension from the Shopware Community Store or our free "ThemeWare® Customizing App" (an extension based on the app system of Showpare 6).

Note: Please use the "ThemeWare® Customizing Plugin" in Shopware 6 (self-managed).


You can find the download link for the free "Customising plugin" via the ThemeWare® Utilities:

Important: Please note that we offer the "ThemeWare® Customizing App" free of charge and cannot provide support for the App or individual customisations.


The app has to be uploaded using the administration of Shopware via "Extensions" => "My extensions" and the button "Upload extension".

Install and activate the plugin after that.

It can happen that the error "Undefined variable $twt-color-brand-secondary-light" appears during activation. However, the app is still activated.

Unable to compile the theme "Storefront". Undefined variable $twt-color-brand-secondary-light...

After activation, recompile your ThemeWare® theme once (just save the theme configuration unchanged, for example) and clear the Shopware cache.

Please find more information regarding the manual installation of extensions in the article:

If the extension has been successfully installed, a JavaScript "test message" and a "test banner" appear in the storefront:

As the plugin is free of charge and not available via the Shopware Store, there is currently no automatic update option.

Deactivate the plugin before you perform a Shopware update. You can find information on how to update your plugin manually below:

Manual update

As all changes are overwritten on file level when updating extensions, it is important to backup the folder custom/apps/TcinnCustomizingApp/src before updating and upload it again after the update.

HinwNote: You can find the latest version in the ThemeWare® Utilities.

Shopware 6.5

To make the customising plugin basically compatible for Shopware 6.5, it is sufficient to modify the required Shopware version in the "_messagebox.scss" file as follows:

color: color-yiq($twt-color-brand-secondary-light);

color: color-contrast($twt-color-brand-secondary-light);

This makes the extension compatible with Shopware 6.5 and it does not need to be updated.
