Caching for a snappier website.
When a WordPress page loads normally, it goes through:
<ol>
<li>PHP execution</li>
<li>Database queries (often 20-50+ queries)</li>
<li>Theme processing</li>
<li>Plugin execution</li>
<li>HTML generation</li>
</ol>
With Snappy file-based caching, it skips all that and just serves a static HTML file.
Estimates for performance improvement:
<ul>
<li>2x faster is conservative and achievable for most sites</li>
<li>5x faster is realistic for database-heavy sites</li>
<li>10x faster is possible for poorly optimized sites with many plugins</li>
</ul>
<h4>Advanced Version</h4>
Snappy is fully capable with its core caching capability, but if you want or need additional optimization and control, advanced settings are available at <a href="https://snappywp.me/" rel="nofollow ugc">snappywp.me</a>.
<ul>
<li>HTML, CSS, and JavaScript minification</li>
<li>GZIP compression</li>
<li>Lazy loading for images and videos</li>
<li>Video embed optimization (YouTube/Vimeo facades)</li>
<li>Font preloading</li>
<li>Database cleanup (spam, revisions, transients)</li>
<li>Automatic weekly database optimization</li>
<li>Cache preloading from sitemap</li>
<li>Defer JavaScript with exclusions</li>
<li>Critical CSS extraction and inlining</li>
<li>WordPress Heartbeat control</li>
<li>Resource hints (preload, prefetch, DNS-prefetch)</li>
<li>Browser caching headers via .htaccess</li>
<li>Security headers (X-Frame-Options, CSP, etc.)</li>
<li>Cloudflare integration with optimized settings</li>
<li>CDN integration with URL rewriting</li>
<li>Settings import/export</li>
<li>Self-hosted update system</li>
</ul>

Update Page Cache flushes and generates again the page cache.
The actual version supports <a href="https://wordpress.org/plugins/w3-total-cache/" rel="ugc">W3 Total Cache</a>, <a href="https://wordpress.org/plugins/wp-fastest-cache/" rel="noopener ugc">WP Fastest Cache</a>, <a href="https://wordpress.org/plugins/wp-super-cache/" rel="ugc">WP Super Cache</a>, and <a href="https://wordpress.org/plugins/wp-optimize/" rel="ugc">WP Optimize</a>.
When you modify a page and save it, usually caching plugins automatically clear the cache of that page, but you need to visit again the page to generate again the cache.
Update Page Cache adds a button on every single page, post and custom post type that you can click to automatically clear and regenerate the cache of that page. Be careful, you will not see the button if you have Fullscreen mode active.
When you edit a single page, if you click on the “Update Page Cache” button, the cache of that page will be automatically updated without the need to visit that page.
In the main settings you can set for each post types if the plugin should automatically clear the page cache when that single post type is saved.
You can also decide which page caches should be updated after saving a specific post type. 
In the example shown in the screenshot of the main settings, when a single blog post is saved Update Page Cache updates the cache of the blog page and homepage. When a contact form is saved, Update Page Cache updates the cache of the page Contact.

Update Page Cache

I'm the author of this plugin, but I'm also a user. I'm installing it on the websites where I use caching plugins and I love it. I love my own plugin, I think it does what is written in the description and make save time. So even though I'm the author, I give it 5 stars.
