Mantys CoreSuper(de)charge
your WordPress
A cloud-powered performance plugin for WordPress. It builds Critical CSS, serves next-gen images, and automatically cuts render-blocking weight, so your pages load faster without touching your theme.
Up and running in minutes
No external build pipeline. No theme modifications. Just activate, configure, and go.
Install the plugin
Upload the zip and activate it in WordPress. No build step, no config files. It works the moment it is active.
Configure your presets
Group your rules per page type: which CSS to inline, which scripts to delay, which assets to drop. Then generate Critical CSS from the dashboard in one click.
Serve optimised pages
Critical CSS is inlined, unused assets stop loading, and your optimised pages are cached and served ready-made from the very first visit.
Every layer of page speed, one plugin
A lightweight, modular engine. Not a bloated all-in-one plugin.
Critical CSS
The CSS your above-the-fold needs is built per page and inlined, so the first paint never waits on a stylesheet. Generated in the cloud, cached and injected automatically.
Used-CSS only
Below the fold, only the CSS a page actually uses is shipped and the rest is dropped. On heavy themes and page builders, it is the single biggest weight you can cut.
JavaScript control
Non-critical scripts are delayed until the visitor interacts, and scripts a page does not need never load at all. Less main-thread work, lighter pages, nothing broken.
Next-gen images
Your images are converted to modern formats, sized for each device, and given the right lazy-load and priority hints, so your largest image lands fast.
Instant delivery
Optimised pages are served ready-made and refreshed in the background, and the next page is prefetched before it is clicked, so navigation feels instant.
Safe & reversible
Every rule lives in WordPress options and applies non-destructively at runtime. Deactivate the plugin and your site is back to baseline, instantly.
And you control every layer of it, per page type. Group your rules into presets and apply them exactly where they belong: one set for your shop, another for your blog, another for a landing page. Nothing runs blindly across the whole site. You decide what applies, and where.
Replaces and improves your current cache system. Or works alongside it.
Mantys includes its own caching. Let it be your whole performance layer, or keep the tools you already use.

Frequently asked questions
Yes. It works at the page-output level, so it is completely theme-agnostic. It has been tested with Divi, Elementor, GeneratePress, Blocksy and plain block themes.
No. Critical CSS is one layer of several. Mantys also ships used-CSS only, controls how JavaScript loads, converts images to modern formats, and caches your optimised pages. You switch on what each page type needs.
Your pages are rendered on our cloud service, which detects exactly which CSS your above-the-fold needs, for both mobile and desktop, and builds a minimal set from it. It refreshes automatically when your pages change.
Mantys includes its own caching, so it can be your whole performance layer with no separate cache plugin needed. Prefer to keep the cache you already have? It works alongside WP Rocket, LiteSpeed Cache, W3 Total Cache and Cloudflare too, applying its changes before your cache stores the page.
Your site returns to its original state immediately. No files are permanently modified. All rules and cache entries are stored in WP options and cleared on deactivation if you choose.
Each plan has a domain limit (1, 5, or unlimited). Your license key is validated per domain by the Mantys gateway, and you get a clear message if you go over your quota.
