BrenWP Cache speeds up WordPress by serving cached HTML pages to anonymous visitors. On a cache miss, WordPress renders the page normally; BrenWP Cache captures the final HTML output and stores it as a file. On subsequent requests, the cached HTML is served early, reducing server load and improving response times.
This plugin is intentionally minimal, transparent, and WordPress.org-friendly: 
* No telemetry, no tracking, no “phone home” 
* No external services or dependencies 
* Admin UI assets are strictly scoped to this plugin’s pages
<h3>Key features</h3>
Full-page file cache for anonymous visitors 
* Caches full HTML documents for GET requests only. 
* Designed for the common “public pages” scenario where most traffic is anonymous. 
* Avoids caching in common non-cacheable contexts such as admin, AJAX, REST, feeds, previews, searches, and similar endpoints.
Rules to prevent caching personalized or dynamic content 
* Exclude logged-in users (recommended; enabled by default). 
* Exclude URLs (one per line): 
 – Prefix rules (e.g. <code>/checkout</code>) 
 – Wildcards (e.g. <code>/cart*</code>) 
* Exclude by cookies (useful for ecommerce/session cookies). 
* Exclude by user agent (bots, scanners, special clients). 
* Bypass query parameter: when present (e.g. <code>?nocache=1</code>) caching is bypassed for that request. 
* Optional 404 caching (disabled by default; enable only if your 404 output is safe and static).
Tools and automation 
* One-click Purge cache tool in WP Admin. 
* Optional auto-purge when posts are updated (useful for content sites that publish/edit frequently).
Security and WordPress.org compliance 
BrenWP Cache is built to meet WordPress.org review expectations: 
* Capability checks + nonces for state-changing admin actions 
* Strict sanitization/validation of input and late escaping for output 
* Cache directory is constrained under <code>wp-content/cache/brenwp-cache</code> with path safety guards 
* Cached HTML is served as a full document (not escaped) and is integrity-verified with an HMAC signature; unsigned/invalid cache is treated as a miss 
* No obfuscation, no remote calls, no dangerous execution patterns
<h3>Recommended usage (important)</h3>
A full-page cache should never store private/personalized output. For best results: 
* Keep “Exclude logged-in users” enabled. 
* Add exclusions for dynamic endpoints such as: 
 – <code>/checkout</code>, <code>/cart</code>, <code>/my-account</code> (WooCommerce) 
 – Any pages that show user-specific data, pricing, currency switching, or session-based content 
* If a page sets cookies or sends <code>Cache-Control: private/no-store/no-cache</code>, it will not be cached.

<h3>Privacy</h3>
BrenWP Cache does not collect personal data and does not send telemetry. Optional Preload requests only your own site URLs. 
Caching is file-based on your server, stored under your WordPress content directory, and controlled by your configuration.

Simple Cache was constructed after getting frustrated with the major caching plugins available and building sites with developer-only complex caching solutions that get millions of page views per day. Simple Cache promises the following:
<ul>
<li>Extremely simple one-click install. There is an on-off switch. That’s it. No need to wade through 50 complicated settings.</li>
<li>Simple Cache makes your site run very fast so you can handle lots of traffic.</li>
<li>Extremely easy to delete. Don’t like the plugin? You can remove it, and your website won’t break.</li>
<li>Easily clear the cache if you need to.</li>
<li>Enable gzip compression</li>
<li>Want to get advanced with object caching (Memached or Redis)? An advanced mode is available that will automatically setup <a href="https://wordpress.org/plugins/batcache/" rel="ugc">Batcache</a> and <a href="https://wordpress.org/plugins/memcached/" rel="ugc">Memcached</a>/<a href="https://wordpress.org/plugins/wp-redis/" rel="ugc">Redis</a> for you.</li>
</ul>
If you need your site to run fast, don’t have time to mess with complicated settings, and have been frustrated by other caching plugins, give Simple Cache a try.

Simple Cache

I had this plugin on about 30 sites two years ago, but have since removed it, one by one, because of bad experiences of many kinds. The last was removed today, after site crashed due to fatal error in caused by the last update to this plugin.

When deactivating it also puts DEFINE('WP_ACHE', false); at the top of wp-config.php. This is bad and makes trouble using another cache plugin, unless this line is manually removed.

I can not recommend this plugin. Be aware of the thing mentioned above, when uninstalling to try out another.

Sorry - bad plugin

A very simple plugin to make your site run lightning fast with caching.
