Mantys CoreThe full performance pipeline
Every layer of page speed, in one plugin
A cloud-powered performance plugin for WordPress. It builds Critical CSS, ships only the CSS a page uses, controls your JavaScript, serves next-gen images, and delivers pages ready-made. Automatically, without touching your theme.
⚡
Critical CSS
Your above-the-fold paints immediately.
- ✓The CSS your first screen needs is built per page and inlined, so the first paint never waits on a stylesheet.
- ✓Generated in the cloud, cached, and injected automatically. No build step on your side.
- ✓Handled for mobile and desktop separately, because they do not show the same thing first.
✂️
Used-CSS only
Ship the CSS a page actually uses, drop the rest.
- ✓Below the fold, only the styles the page really needs are served.
- ✓On heavy themes and page builders, it is the single biggest weight you can cut.
- ✓Applied per page, so a landing page and a shop page each get exactly what they use.
🧠
JavaScript control
A lighter, calmer main thread.
- ✓Non-critical scripts are delayed until the visitor interacts.
- ✓Scripts a page does not need are never loaded at all.
- ✓Dependency-aware, so deferring one script does not silently break the one that needs it.
📸
Next-gen images
Modern formats, at the right size, automatically.
- ✓Images are converted to modern formats and sized for each device.
- ✓The right lazy-load and priority hints, so your largest image lands fast.
- ✓Width and height are set to stop the layout from jumping while it loads.
🚀
Instant delivery
Pages that feel instant to move through.
- ✓Optimised pages are served ready-made and refreshed in the background, so they are never stale.
- ✓The next page is prefetched before it is clicked, so navigation feels immediate.
- ✓Edge cache is purged automatically when you update a page.
🎯
Scopes & presets
Precision, not a blanket switch.
- ✓Group your rules into presets and apply them per post type, template, or URL.
- ✓One set for your shop, another for your blog, another for a landing page.
- ✓Nothing runs across the whole site by accident. You decide what applies, and where.
🛡️
Safe & reversible
Nothing destructive, ever.
- ✓Every rule lives in WordPress options and applies non-destructively at runtime.
- ✓A built-in diagnostic shows exactly what ran on any page, and why.
- ✓Deactivate the plugin and your site is back to baseline, instantly.
🧩
Works with your stack
A complement, not a replacement.
- ✓Mantys applies its changes before your cache stores the page, so it works alongside WP Rocket, LiteSpeed Cache, W3 Total Cache and Cloudflare.
- ✓Theme-agnostic: tested with Divi, Elementor, Bricks, GeneratePress, Blocksy and plain block themes.
- ✓It does the layer your cache does not: per-page Critical and used-CSS, images, and JavaScript.
