Maximize Your
Cache HIT Ratio
Complete cache optimization and page performance for WordPress sites behind Varnish, Nginx, or CDN caches. Fewer misses, faster Core Web Vitals, happier visitors.
New in v2.1: built-in Redis object cache and a native full-page cache. Run them alongside Varnish, or drop Varnish entirely. Your call.

Compatible with Varnish, NGINX FastCGI Cache, Cloudflare, and all major CDNs

Everything You Need for Perfect Caching
From automatic cache warming to intelligent headers, Cacheability Pro handles the complex caching logic so you don't have to.
Cache Warming
Automatically warm pages after purge so visitors never hit cold cache. Smart queue prioritizes homepage, categories, then recent posts.
Conditional GET (304)
Returns 304 Not Modified for unchanged content, saving bandwidth and reducing server load.
Soft 404 Fixes
WordPress returns 200 OK for empty archives. We return proper 404 status codes to improve your SEO.
Smart Cache-Control
Context-aware TTLs with s-maxage, stale-while-revalidate, and per-page-type policies.
ESI Support
Edge Side Includes for nonces — cache pages while keeping forms working. Works with Varnish & Fastly.
Cache Diagnostics
Context-aware code scanning detects plugins and themes that break caching. Dismiss findings, deactivate culprits directly from diagnostics.
Built-in Redis Object Cache
A drop-in WP_Object_Cache backend that supersets the popular incumbents.
Single round-trip MGET instead of per-key loops, site-scoped flush via
SCAN + UNLINK (never FLUSHDB), object-injection-safe
deserialization, plus TLS and Redis 6 ACL built in. Install with one constant:
WP_REDIS_URL.

Native Full-Page Cache
An optional advanced-cache.php drop-in that removes the Varnish or
NGINX-front requirement. ESI keeps working without an upstream proxy
via a loopback resolver. W3TC / WP Rocket on-disk layout (existing nginx
try_files rules keep working), optional Redis hot tier, WP Rocket-style
bypass semantics, and automatic purge through varnish-http-purge.

Page Optimization, Built In
Five new features that improve Core Web Vitals scores automatically. No settings to configure — install the plugin and go.
Resource Hints
Auto DNS prefetch, preconnect, and font preloading for external resources. Saves 50-300ms per domain on first load.
Improves LCP New in v1.1Defer JavaScript
Adds defer to scripts for faster first paint.
Auto-excludes jQuery and ES modules. Custom exclusion list available.
Image Dimensions
Adds missing width/height and aspect-ratio CSS to images.
Prevents Cumulative Layout Shift.
Heartbeat Control
Disables frontend heartbeat, reduces admin dashboard to 120s interval, keeps editor unchanged. Fewer AJAX requests, less server load.
New in v1.1Emoji Cleanup
Removes the 15KB emoji polyfill script and styles. All modern browsers render emojis natively — no polyfill needed.
-15KB page weight New in v1.1How We Compare
