DM Super Cache — Free WordPress Caching & Speed Plugin

A lightweight WordPress caching plugin built to improve page speed and Core Web Vitals: full-page caching, CSS minification, JavaScript deferral, async Google Fonts, and image lazy-loading — without the bloat of a full optimization suite.

Version 1.0.1 Requires WP 5.8+ Tested up to 7.0 GPLv2 or later 100% Free

Why your WordPress site needs a caching plugin

Every uncached page load makes WordPress rebuild the same HTML from PHP and MySQL from scratch. A caching plugin serves a pre-built static copy instead, which is the single biggest lever for improving page speed, Core Web Vitals, and search ranking on a WordPress site.

What DM Super Cache does

Five focused features, each aimed at a specific part of your PageSpeed score.

Full-Page Caching

Serves static HTML snapshots to logged-out visitors, skipping PHP and database queries entirely on repeat requests.

CSS Minification

Automatically minifies first-party stylesheets and serves the compressed version from a local cache folder.

JavaScript Deferral

Defers non-critical scripts so the browser paints the page before running them, with an exclude list for scripts that must load immediately.

Font Optimization

Loads Google Fonts asynchronously via preload + noscript, so web fonts never block the initial render.

Lazy-Loading

Adds native lazy-loading to below-the-fold images and iframes, while leaving your first image eager for a fast LCP.

One-Click Cache Clear

An admin-bar button clears the cache instantly, and it auto-clears on publish, comment, theme switch, or plugin change.

Installation

No configuration required to get started — sensible defaults are enabled out of the box.

Frequently asked questions

Is DM Super Cache really free?

Yes. It’s fully free and GPLv2-licensed, with no premium tier, upsells, or usage limits.

Will it conflict with other caching plugins?

Running two full-page cache plugins at once can cause conflicts. Deactivate other caching plugins before activating DM Super Cache.

Does it work with any WordPress theme?

Yes. It hooks into WordPress’s own template and output-buffering system, so it works independently of your theme or page builder.

Does caching affect logged-in users or WooCommerce carts?

No. Full-page caching only applies to logged-out visitors, so dynamic content like carts and account pages are always served fresh.
