What is Cache Enabler?

Cache Enabler - Simple Caching Plugin by KeyCDN

What if we could (almost) make your WordPress website load much faster? And what if we could do it pretty easily and in a hassle-free way?

Cache Enabler is a free plugin for caching static HTML files, which can increase the speed of your WordPress site.

It uses static files instead of generating (and then consuming) dynamic server-side output, such as PHP or SQL queries.

This means that your WordPress site will not only improve in performance, but you will also reduce overhead by speeding up the resource-intensive backend operations without resorting to expensive hardware or cloud hosting.

Cache Enabler is available in the WordPress directory, but it doesn’t have any premium plans. It offers all the features one would expect from a caching plugin, though, can be used paying nothing at all!

Let’s look at the important features Cache Enabler offers now that we’ve got that out of the way.

  • The fast and efficient cache engine
  • Automatic smart cache clearing
  • Manual cache clearing
  • WP-CLI cache clearing
  • Cache expiry
  • WebP support (convert images to WebP with Optimus)
  • Mobile support
  • Brotli and Gzip pre-compression support
  • Minification of HTML excluding or including inline CSS and JavaScript
  • Real-time cache size display in the WordPress dashboard
  • Custom post type support
  • 304 Not Modified support
  • Works perfectly with Autoptimize and most other third-party plugins.

Cache Enabler Settings

WPRocket Setting Page

Cache Behaviour:

  • Expiration: You will set cache expiration here, default is 0, Unless you’re often adding content to your site regularly, we recommend leaving the function it at the default setting. But you have to manually clear the cache every time after updating the contents.
  • Clearing: You can see five check boxes with condition displayed here, so every time you hit the save button, caches cleared automatically.
    • ✅ Clear the site cache if any post type has been published, updated, or trashed (instead of the post cache).
    • ✅ Clear the site cache if a comment has been posted, updated, spammed, or trashed (instead of the comment cache).
    • Clear the site cache if a term has been added, updated, or deleted (instead of the term cache).
    • Clear the site cache if a user has been added, updated, or deleted (instead of the user cache).
    • ✅ Clear the site cache if a plugin has been activated or deactivated.
  • Versions:
    • Create a cached version for WebP support. Convert your images to WebP with Optimus.
    •  Create a cached version for mobile devices.
    •  ✅ Create a cached version pre-compressed with Gzip. (Needs to be disabled if the decoding fails in the web browser.)
  • Minification: You have two choices here, I choose including inline CSS and JavaScript, you can choose excluding inline CSS and JavaScript.
    • ✅ Minify HTML in cached pages including inline CSS and JavaScript.

Cache Exclusions: If you don’t want any of your posts or pages cached, you can simply add them to the list in the Cache Exclusions POST IDS or PAGE PATH text area. To do this, simply go to the Edit Post or Edit Page screen for whichever post or page you’d like to add then look at the URL for that specific post/page, find your blog’s post/page ID listed there at the end, and just type it into the Cache Exclusions field here.

Cache Enabler vs WP Rocket

If you read my WP Rocket review, then you can find how easy to configure it and make WordPress faster.

Cache Enabler is the free solution for your caching needs, but if you compare it with WP Rocket, you’ll find it’s missing some most important features like minification of CSS and JS files, Lazy Loading images, and videos and database cleaner.

So comparing apple to apple, I am using Autoptimize, Rocket Lazy Load, and ShortPixel with Cache Enabler.

Conclusion based on Fully Loaded Time

As you can see, WP Rocket is 15% faster than Cache Enabler and doesn’t require four extra plugins.

You can beat or come close to the premium WP Rocket result but it requires you to play with lots of free plugins and configurations. WP Rocket provides you the ease of mind which costs money.
