What it does
If you look after several WordPress sites that run WP Rocket, changing cache settings usually means signing into every site backend one at a time. This extension moves that work into the MainWP Dashboard you already use. From there you can set caching preferences, clear caches and preload them across your connected Child sites, which cuts down on repetitive admin tasks and keeps settings consistent from site to site.
The extension requires MainWP and works with the WP Rocket options on each Child site. Along with cache controls, it covers file optimization settings such as minifying HTML, CSS and JavaScript, combining CSS and JS files, deferred loading of images and JavaScript, and CSS delivery options like loading CSS asynchronously. A self-hosted crawler bot visits your sites to generate cache files ahead of time, so visitors get cached pages from the start. It suits agencies, freelancers and businesses running a network of WordPress sites.
Best for
- Agencies managing WP Rocket on many client sites
- Freelancers who maintain several WordPress sites through MainWP
- Businesses running a network of WordPress websites
Features
Central WP Rocket settings
Manage WP Rocket settings for every connected Child site from one MainWP Dashboard, so you no longer switch between individual site backends to make changes.
Clear and preload caches
Clear or preload caches across multiple sites from the MainWP interface, which helps keep cached content current after you publish or update pages.
Self-hosted crawler bot
A crawler bot visits your sites and generates cache files in advance, so visitors are served cached versions of pages as soon as they arrive.
File minification
Turn on minification for HTML, CSS and JavaScript files on your Child sites, reducing file size without editing each site by hand.
Combine CSS and JS files
Set WP Rocket to combine CSS and JavaScript files on managed sites, cutting down the number of separate files a browser has to request.
Deferred image and script loading
Configure deferred loading of images and JavaScript so these resources load later in the page process, set centrally for the sites you manage.
CSS delivery options
Manage the Optimize CSS delivery setting, including the Load CSS Async option, for your Child sites directly from the dashboard.

Questions about MainWP Rocket
Do I need MainWP and WP Rocket to use this extension?
Yes. It is an extension for MainWP, so it runs inside your MainWP Dashboard. It controls WP Rocket settings on your connected Child sites, so those sites need WP Rocket to apply the caching and optimization options you set.
Can I clear the cache on all my sites at once?
You can clear or preload caches across multiple Child sites from the MainWP interface. This saves you from logging into each site separately whenever content changes and the cache needs refreshing.
What does the crawler bot do?
The self-hosted crawler bot visits your sites and generates cache files ahead of time. That way, when a real visitor lands on a page, a cached version is already ready to be served instead of being built on the first request.
Which optimization settings can I manage from the dashboard?
Along with cache settings, you can manage minification of HTML, CSS and JavaScript, combining CSS and JS files, deferred loading of images and JavaScript, and CSS delivery options such as loading CSS asynchronously.
