Best caching plugins.

As your WordPress site grows, you may notice a dip in its performance. If you’ve been tinkering with it for a bit but haven’t seen a meaningful improvement in your page loading times, then the answer to your troubles might lie in caching! To put it more specifically, your website might strongly benefit from using one of the best caching plugins available for WordPress.

To help you get started, we’ve researched and rounded up five of the best caching plugins out there. Besides sharing information about each one, we’ll also make some recommendations for which plugin to choose based on your needs and experience level.

First, let’s briefly review what caching actually is and why it’s so helpful. If you’re already familiar with the concept, then feel free to skip ahead to the list of caching plugins. Let’s go!

What is caching and why is it valuable? 🤔

In a general sense, caching means storing "something" in a temporary storage area so that it can be more easily retrieved. For your WordPress site, caching is important because it can make your pages load faster and reduce the load on your server.

The most common type of caching for WordPress sites is page caching, in which your site stores a static HTML version of each page, rather than dynamically building each page with PHP and database queries like WordPress normally would.

But there are also other types of caching that WordPress sites can benefit from, including:

  • Database caching: Most common queries (like getting the list of posts for your homepage) are cached to avoid a redundant database query altogether.
  • Browser caching: This is the process of storing files on the browser for quick rendering and can be triggered by your server.
  • Object caching: An object is a collection of files (documents, scripts, images), so object caching involves storing a bunch of these files locally.

Some caching plugins focus almost exclusively on page caching, while others offer a more comprehensive approach.

Let’s get to the plugins now. 🚀

Best caching plugins for WordPress in 2024 🔌

  1. LiteSpeed Cache
  2. WP Fastest Cache
  3. WP Rocket
  4. WP Super Cache
  5. W3 Total Cache

1. LiteSpeed Cache

If you're looking for a straightforward caching plugin with a robust set of optimization features, you may want to consider LiteSpeed Cache.

The plugin gives you everything you need to speed up your site. This includes server caching, and minification of cascading style sheets (CSS), JavaScript (JS), and HTML. Furthermore, it enables you to optimize images and defer or delay the loading of non-essential JS:

LiteSpeed Cache also supports third-party object caching and Content Delivery Networks (CDNs). While some of the other tools on this list come with those features built-in, they usually require a premium plan.

All in all, LiteSpeed Cache gives you a generous collection of caching and performance optimization features for being a free tool.

Key features ⚙️

  • Server-level caching
  • Performance features like image optimization, deferring non-essential JS, and more
  • Supports CDNs and object caching
  • Supports WordPress Multi-site

Pricing 💰

The LiteSpeed Cache plugin is completely free.

2. WP Fastest Cache

WP Fastest Cache is a little more comprehensive than some other options on this list, as it provides a few other performance-boosting features outside of caching:

For example, it gives you the option to integrate it with a CDN. This way, static files like scripts and images can be rendered through the CDN to reduce load times.

What's more, there's an option to create “exclude rules” to leave out certain web pages, JS scripts, CSS files, and cookies from being cached. This option can be useful if you have pages that go through frequent changes, like the homepage of an e-commerce website.

Key features ⚙️

  • Page and browser caching with straightforward configuration
  • Performance features such as a CDN, minification options, and GZIP compression
  • Option to exclude rules so you can select which pages aren't cached
  • Advanced features (premium) like database cleanup, image optimization, and more

Pricing 💰

Although most of the features in WP Fastest Cache are free, you can get more advanced functionality when you purchase the premium version for $49.

Premium options include the ability to delete a cache, image optimization and compression, and cleanup of your MySQL database.

3. WP Rocket

WP Rocket is a powerful premium caching plugin. Similar to WP Fastest Cache, it enables you to cache pages, minify static files, and integrate with a CDN (though it has its own tool, RocketCDN).

The plugin also lets you delay the execution of JavaScript (JS) files, which helps improve Core Web Vitals metrics like largest contentful paint (LCP) and first input delay (FID).

The main downside to this plugin is that it doesn't offer a free version. It's worth noting though that WP Rocket also happens to be the caching solution that we use on this blog!

Key features ⚙️

  • Caches pages, minifies static files, and integrates with CDNs
  • Loads images only when a user scrolls over them
  • Delays non-essential JS files and cleans your database
  • Offers extensive documentation and a support section

Pricing 💰

WP Rocket is a premium plugin, which is easy to set up and use. There's a 14-day money-back guarantee with plans starting at $59 per year.

4. WP Super Cache

WP Super Cache is developed by Automattic, the company behind WordPress.com, and a major contributor to WordPress. The plugin provides logically grouped options that go hand in hand with the types of caching mentioned earlier in the post:

You can also enable WP Super Cache in a single click. Plus, this plugin provides support for CDNs like WP Fastest Cache.

To put it simply, WP Super Cache gives you all the settings you'd expect from a WordPress caching tool, and more. For instance, it has a debug mode that creates cache logs. This can be helpful in case you're not getting the desired performance improvements from the plugin and you want to explore the reasons behind the issue.

Key features ⚙️

  • Select a delivery method for the caching
  • Exclude certain users from seeing cached content
  • Rebuild the cache manually if needed
  • Control caching for mobile devices
  • Specify a location for cache files
  • Enable debug mode

Pricing 💰

WP Super Cache is a free plugin.

5. W3 Total Cache

W3 Total Cache is one of the most popular and best caching plugins for WordPress sites, though it's geared a little more towards advanced users. It offers an array of different caching methods, including page caching, database caching, object caching, and browser caching:

In addition to the features provided by other plugins, W3 Total Cache has an option to minify your static files in order to reduce their size and make load times shorter. Moreover, there is an option to import and export settings, which can be a lifesaver when you are migrating your site across servers.

Overall, W3 Total Cache is a complete solution for caching in WordPress. It gives you a comprehensive set of options, which makes it one of the best caching plugins for WordPress.

The only catch is that it can take some time to set up. But don't worry - we have a beginner's guide to setting up W3 Total Cache!

Key features ⚙️

  • Multiple caching options, including page, browser, object, and database
  • Performance features such as minification and CDN integration
  • Option to import/export settings
