QuantumCache accelerates WordPress by caching database query results and content fragments used to build pages. Instead of caching entire HTML pages, it reduces the database work required to render pages while preserving WordPress’s native invalidation behavior.
It is not an output buffer or page cache, and it does not replace existing page caching solutions.
<h3>Features</h3>
<ul>
<li>Caches the results of the main front-end <code>WP_Query</code> for anonymous requests.</li>
<li>Tag-based invalidation: purge by post ID, post type, or taxonomy.</li>
<li>Fragment caching for <code>the_content</code> (classic) and core blocks such as <code>core/post-content</code>, <code>core/latest-posts</code>, <code>core/archives</code>, and <code>core/navigation</code>.</li>
<li>Multiple storage modes:
<ul>
<li>Auto – use Redis if available, otherwise fall back to MySQL.</li>
<li>Redis – fastest mode; uses the PHP Redis extension.</li>
<li>MySQL – portable fallback using compact tables (<code>qc_entries</code>, <code>qc_tagmap</code>).</li>
</ul>
</li>
<li>Compatible with the Redis Object Cache drop-in.</li>
<li>Avoids wp_options and postmeta storage – all cache data is stored in Redis or 
QuantumCache-owned database tables.</li>
<li>Multisite-aware: per-site prefixes and per-site tables.</li>
<li>WP-CLI commands: <code>wp quantumcache flush</code> and <code>wp quantumcache status</code>.</li>
<li>Metrics data layer: persistent hit, miss, store, and purge event counters available via <code>Metrics::totals()</code> and <code>Metrics::deltas()</code>.</li>
</ul>
<h3>Performance summary</h3>
In benchmarks on a plugin-heavy WordPress site (WooCommerce + Yoast SEO), 
QuantumCache reduced per-request database queries by up to ~99% on cached pages 
and achieved cache hit rates exceeding 97% with Redis.
In the benchmark environment:
<ul>
<li>Redis mode reduced warm TTFB by roughly 23–27% and total response time by 18–21% versus an uncached baseline.</li>
<li>MySQL fallback mode delivered modest improvements (~3–10%) when Redis was unavailable.</li>
</ul>
Actual results depend on theme complexity, plugin load, database topology, and traffic patterns.
<h3>When to use QuantumCache</h3>
QuantumCache is useful when:
<ul>
<li>Your site already uses a page cache (such as a CDN, reverse proxy, or caching plugin) but WordPress still performs significant database work.</li>
<li>You want faster response times without relying solely on full-page caching.</li>
<li>Your hosting environment supports Redis, or you want a portable MySQL fallback.</li>
</ul>
QuantumCache complements page caching rather than replacing it.
<h3>What QuantumCache does NOT do</h3>
QuantumCache is not a page cache or full HTML cache.
It does not replace solutions such as: 
* CDN caching 
* reverse proxy caches 
* traditional WordPress page caching plugins
Instead, QuantumCache reduces the database work required to build pages, making those systems more effective.
<h3>Debug headers (optional)</h3>
Enable Settings → QuantumCache → Send X-QC debug headers to view cache status in HTTP responses: 
* <code>X-QC-Main: HIT | MISS | STORE</code> 
* <code>X-QC-Store: AUTO | redis | mysql</code> 
* <code>X-QC-Hydrated:</code> number of posts loaded from cache
Append <code>?qc_nocache=1</code> to any URL to bypass caching for that request.
Debug headers are sent only when explicitly enabled in settings and contain no 
personal or user-specific data.
<h3>WP-CLI commands</h3>
QuantumCache provides the following WP-CLI commands:
wp quantumcache status 
Shows the active backend, storage mode, and lifetime cache counters.
wp quantumcache flush 
Clears all cache entries for the current site.
Use –yes to skip the confirmation prompt.
<h3>QuantumCache Pro</h3>
QuantumCache Pro extends the core engine with advanced caching capabilities for WooCommerce and logged-in users.
See: https://quantumcache.io
<h3>Privacy</h3>
QuantumCache does not collect, send, or log personal data. 
It stores cache entries in Redis or its own MySQL tables. 
Other plugins on your site may handle cookies or data independently. 
No remote requests are made, and no data is transmitted to external servers.

QuantumCache

Speeds up WordPress by caching database queries and fragments for anonymous visitors using Redis or MySQL, without storing cache data in wp_options.

<h3>External Services</h3>
This plugin optionally connects to the following external services. These services are only used when you explicitly enable and configure them in the plugin settings. No data is sent unless you opt in.
Cloudflare API v4
This service is used to purge Cloudflare CDN cache when you enable the Cloudflare cache purge feature. It is needed to send cache purge requests for your Cloudflare zones.
<ul>
<li>What data is sent: Your Cloudflare API token and Zone ID (stored in your WordPress database) are used to authenticate purge requests. No user data or content data is transmitted.</li>
<li>When data is sent: Only when you manually purge cache or when auto-purge triggers and Cloudflare is enabled.</li>
<li>Where data is sent: https://api.cloudflare.com/client/v4/</li>
<li>Terms of Service: https://www.cloudflare.com/terms/</li>
<li>Privacy Policy: https://www.cloudflare.com/privacypolicy/</li>
</ul>
LiteSpeed Admin API (optional)
If configured, the plugin can send purge requests to a LiteSpeed Admin API endpoint. This is entirely optional and only used if you provide the Admin URL and API key in settings.
<h3>Why FlynCache Purge?</h3>
Managing cache across multiple layers (server cache, object cache, CDN cache) is complex. Each cache has its own purge method, API, and configuration. FlynCache Purge unifies all cache management into a single, intelligent interface that auto-detects your setup and handles purging automatically — so you never have to worry about stale content again.
<h3>Supported Cache Types</h3>
<ul>
<li>Nginx FastCGI Cache — File-based cache used by Nginx with PHP-FPM (supports Webinoly, EasyEngine, ServerPilot, and custom configs)</li>
<li>Redis Object Cache — Via phpredis extension, supports host/port/unix socket, authentication, and database selection</li>
<li>LiteSpeed Cache — Server-level cache + LSCWP plugin integration</li>
<li>Cloudflare CDN — API token-based cache purge with zone support</li>
<li>Custom CDN — Any CDN with HTTP purge API (KeyCDN, StackPath, BunnyCDN, Fastly, etc.)</li>
</ul>
