Every optimisation in detail: images, scripts, CSS, resource hints and HTML, plus an acceptance checklist.
Shopware 6.6 or 6.7 with storefront, PHP 8.2 or newer. One package covers both versions.
Install via the Plugin Suite or upload the ZIP under Extensions, install and activate. Then clear the cache.
Both options are off by default because they can have side effects depending on the theme.
Preconnects and font preloads run fully automatically. The input fields are only meant for manual overrides and take precedence.
External origins are detected in the delivered HTML, at most four automatic ones, excluding your own host. For font hosts crossorigin is set, otherwise not - so the browser actually reuses the connection.
An info box in the module shows live which preconnects and fonts are currently being set.
If a page briefly looks unstyled after enabling "asynchronous CSS", switch the option off again - that would require critical inline CSS in the theme. If a widget disappears after "defer scripts", add it to the exception list.

Every setting of the plugin with its default value and explanation, in the same order as in the administration. The texts come straight from the plugin (version 1.0.21).
Settings apply to the selected sales channel. Without own values a channel inherits the settings of All sales channels.
Master switch. When off, nothing is changed.
Adds loading="lazy" and decoding="async" to images that have no loading attribute yet.
This many images at the top stay eager (protects the LCP image).
Adds loading="lazy" to iframes (maps, videos, etc.).
Sets fetchpriority="high" on the first image and adds a preload link in the head.
Adds missing width/height to images from the dimensions in the Shopware thumbnail URL. Reserves the space before loading and reduces layout shifts (CLS).
Adds a srcset built from the Shopware thumbnail variants to images delivered as original uploads (e.g. CMS banners). The browser then loads the fitting size instead of the full original - a big lever for banners on mobile. The original stays as fallback. After enabling, check the home page: if banners look blurry, large thumbnail sizes are missing in the media settings or the image belongs in the exceptions.
Images whose URL contains one of these text fragments are not touched.
Adds defer to external scripts without async/defer. Careful: can break scripts with strict order. Off by default.
Scripts whose src contains one of these fragments are left untouched.
Loads stylesheets non-blocking (loadCSS pattern with noscript fallback). Biggest lever against render-blocking requests. Caution: without critical inline CSS the page can flash unstyled briefly (FOUC) - after enabling, check home page, listing and checkout. Off by default.
Stylesheets whose URL contains one of these text fragments keep loading blocking.
Fully automatic: external origins (CDN, widgets, tag manager) are detected from the HTML and preconnected, the theme fonts are determined from the theme CSS and preloaded. The fields below are only needed for manual overrides.
Optional. Leave empty for automatic mode - entries supplement the automatically detected origins. e.g. https://fonts.gstatic.com
Optional. Leave empty for automatic mode - the plugin then reads the fonts itself from the theme CSS (independent of the theme hash). Entries replace the automatic mode. Full URLs to .woff2/.woff/.ttf files.
Reduces whitespace and removes comments. pre/textarea/script/style stay untouched. Off by default.
Prefetches internal links on hover/tap so the next click is instant.
Address of a shop page to analyse. Left empty, the home page of the selected sales channel is checked. The analysis shows which external sources, fonts and images the page loads and serves as the basis for the automatic resource hints.
No booking needed, no term.
Download the free Plugin Suite and upload it in the admin, no SSH needed. It installs and updates the plugin with one click. You buy the licence directly from us, with an invoice from us and support straight from the developer.
The plugin will be listed in the official Shopware Community Store. Installation and automatic updates then run through the plugin manager in the backend, billing through your Shopware account. We will link it here as soon as it is available.
