Everything Clix Cache does

Five feature groups. One clean dashboard.

Every setting lives in one place. Turn on what you need, ignore what you don't. Built to WordPress core coding and security standards, shipped as a single install.

01

Cache & Delivery

Full-page caching served straight from your web server.
  • Full-page caching with GZIP compression, served directly by the web server
  • Automatic cache clearing when you install, update, deactivate or delete plugins and themes
  • Cache preloading so visitors never hit a cold cache
  • One-click Cloudflare edge purge via Cloudflare's official API
  • CDN URL rewriting for static assets
02

Speed & Core Web Vitals

Real-user metrics from your actual visitors, not lab scores.
  • Real-user monitoring of TTFB, LCP, CLS and INP — actual visitor experience
  • Automatic WebP conversion for newly uploaded images
  • Preload links on hover so the next click feels instant
  • HTML minification and JavaScript defer
  • Reduce layout shifts by adding missing width/height to images
03

Mobile Performance

Phones download phone-sized files, decoded on the side.
  • Responsive image srcset/sizes on every local image
  • decoding="async" on all images
  • Preconnect and DNS-prefetch hints for external asset origins
  • Guaranteed viewport meta tag
  • Aggressive lazy loading below the fold
04

Housekeeping

Database cleanup, lazy-loading, admin bar shortcuts.
  • Database optimization: revisions, auto-drafts, spam, expired transients
  • Native lazy-loading for images and iframes
  • Admin bar shortcut: Clear Cache, Rebuild Cache, Optimize DB, Settings, Help
05

Security & Privacy

Written the way WordPress core is written.
  • Every admin action nonce-protected and capability-checked
  • All settings sanitized in one function; all output escaped
  • Cloudflare API tokens stored securely, sent server-to-server
  • Web Vitals endpoint accepts anonymous numeric data only

Nothing phones home. Nothing sends visitor data to third parties.

No cookies. No IPs. No identifiers. Web Vitals data is anonymous, numeric, and lives on your server.
Getting started

From WordPress.org to warmed cache in four steps.

No setup wizards, no fake progress bars. Install, activate, and Clix Cache turns on sensible defaults automatically.

STEP 01

Install from WordPress.org

Search "Clix Cache" in the Plugins → Add New screen, or download the ZIP direct.

Plugins → Add New → Clix Cache
STEP 02

Activate

One click. Full-page caching, WebP conversion and mobile optimisations turn on with safe defaults.

wp plugin activate clix-cache
STEP 03

Connect Cloudflare (optional)

Paste your Cloudflare API token in Settings → Cloudflare for one-click edge purges.

Settings → Cloudflare → Connect
STEP 04

Rebuild the cache

Trigger a preload from the admin bar. Clix Cache warms every URL on your sitemap in the background.

Works on any WordPress site

Shared hosting, VPS or managed — no special stack required.

Clix Cache is written to WordPress core coding standards, ships as a single install, and works on any host that runs WordPress. No Node, no Docker, no proprietary edge layer.

If your site works, Clix Cache works. And if something doesn't, you can disable any single feature independently — the dashboard is designed around that.

Common questions

Clix Cache FAQ

The questions we get most often about the free version.

Is Clix Cache really free?

Yes. The plugin distributed on WordPress.org is free forever, with no locked features and no in-admin upsell popups. Clix Cache Pro is a separate, optional commercial plugin — it adds features but doesn't gate what's in Free.

Does Clix Cache send any data to your servers?

No. The plugin makes no outbound calls to Clix or third parties. The real-user Web Vitals endpoint stores anonymous numeric performance data on your server only — no cookies, no IPs, no identifiers.

Will it conflict with my host's caching or Cloudflare?

Clix Cache is host-agnostic and knows how to coexist with server-level caching and Cloudflare. Cloudflare integration uses the official API for one-click edge purges. If your host already runs LiteSpeed or NGINX caching, you can disable Clix Cache's page cache and still use the WebP, mobile, database and Web Vitals features.

Do I need to configure it after install?

Sensible defaults turn on at activation. Most sites don't need to touch anything except pasting a Cloudflare API token (optional). Advanced controls are one click deeper if you want them.

What happens to my data if I uninstall?

Uninstall cleanly removes cache files, the Web Vitals table, and plugin options. No orphan tables, no leftover cron jobs. Deactivation without uninstall keeps your settings intact for re-activation later.

Do you offer support for the free version?

Support for Clix Cache Free is provided through the WordPress.org support forum on a best-effort basis. Priority email support is available with Clix Cache Pro.
