Your website’s performance plays a pivotal role in its success. If your pages take too long to load, it increases the likelihood that visitors will ‘bounce’ (leave immediately). The good news is that WordPress cache plugins can help speed up your site. However, it can be difficult to decide which one is right for you.

In this post, we’ll introduce you to these tools and explore their benefits. Then we’ll run through six of the best WordPress cache plugins you can find, detailing their key features and pricing.

Let’s get started!

An Introduction to WordPress Cache Plugins

Before we jump into our list of the best WordPress cache plugins, it’s important first to understand what caching is and how it works. Every time a user visits your WordPress site, the Content Management System (CMS) sends a request to the database to retrieve the required media, JavaScript, CSS, and so on.

In a nutshell, caching helps speed up your website and enhance its performance by temporarily storing data that’s frequently requested from your site’s files. As a result, the information becomes more easily accessible, meaning that it will load faster for your visitors.

WordPress cache plugins help reduce the load on your hosting server by using fewer resources and creating a more responsive website. In turn, these tools can help you improve your User Experience (UX), and may even boost your Search Engine Optimization (SEO).

There are a variety of WordPress plugins to choose from. However, it’s important to spend some time researching and carefully vetting each option. You’ll only want to use one cache plugin, as using more can lead to compatibility and integration errors.

6 Best WordPress Cache Plugins

Now that we’ve looked at what caching is and its benefits, let’s explore some tools you can use to implement it. Below are six of the best WordPress cache plugins to consider.

We considered a handful of factors to create this list, including features, updates and support, and pricing. In addition, all of these tools are widely used and highly rated.

1. W3 Total Cache

The W3 Total Cache WordPress plugin.

With over one million active installations, W3 Total Cache is one of the most popular WordPress cache plugins available. It offers a plethora of options:

WP Rocket lets you automatically minify CSS, HTML, and JavaScript, as well as leverage a wide range of caching options (including content in memory or on disk). You can also use it to defer non-critical CSS and JavaScript so that pages render faster

There is an abundance of options to sort through and configure, and with the pro version you can access even more features. However, if you stick with the free plugin, the default settings should suffice for standard caching needs.

Key Features:

  • Database, object, and browser cache
  • Content Delivery Network (CDN) support and integration
  • Caching and minification of HTML, JavaScript, and CSS
  • GZIP compression
  • Compatible with nearly every type of hosting
  • Mobile and Accelerated Mobile Pages (AMP) support
  • Secure Socket Layer (SSL) support
  • Debug mode

W3 Total Cache is for you if…

… you’re at least moderately familiar with caching. It might be a bit difficult to use as a beginner, given the number of settings and configurations on offer. With that being said, even the free tier is a powerful solution.

Price: Free, with premium licenses starting at $99 per year | More Information

2. WP Rocket

The WP Rocket cache plugin for WordPress.

WP Rocket is one of – if not the – best WordPress caching tools out there. Although it does offer a free lazy load extension, WP Rocket is primarily a premium plugin. It comes with a wide variety of robust features for speeding up your website.

It’s also incredibly easy to use for beginners, and boasts an intuitive User Interface (UI). Both the setup process and options are simple to navigate. To enable caching, all you have to do is activate the plugin – no configuration needed.

Key Features:

  • Quick setup and clean UI
  • GZIP compression
  • Page and browser caching
  • Cache preloading
  • eCommerce optimization
  • Database optimization
  • Compatible with most hosting providers
  • Minification tools
  • Cloudflare and multisite compatibility
  • Robust support

WP Rocket is for you if…

… you’re looking for the most powerful caching option out there, and don’t mind paying for a premium plugin. It also comes with a lot of support and documentation, thanks to its expansive user base. WP Rocket is also recommended if you have a large or complex website, such as an e-commerce site.

Price: Free, with premium licenses starting at $49 per year | More Information

3. WP Super Cache

The WP Super Cache WordPress cache plugin.

WP Super Cache is another well known, highly rated, and completely free WordPress cache plugin. With over 2 million active installations, you can feel confident that it’s an effective and reliable entry in your website’s toolbox. It also promises that “99% of your visitors will be served static HTML files”.

The settings are straightforward, well organized, and easy to understand:

Key Features:

  • Cache served in three levels (Expert, Simple, WP-Cache)

The WP Fastest Cache plugin.

WP Fastest Cache is another free and feature-rich WordPress cache plugin that has over 1 million active installations. It uses mod rewrite to cache pages. You also have the option to apply CSS and HTML modification:

For how straightforward this free plugin is, it’s also impressively powerful and flexible. However, if you’re interested in taking it a step further, you can also upgrade to a premium version (even directly from your dashboard).

  • Desktop and browser caching
  • Cache files deleted post-publication
  • HTML and CSS minification
  • GZIP tools
  • Cache timeout for specific pages and posts
  • CDN, Cloudflare, and SSL support
  • Preload caching

WP Fastest Cache is for you if…

… you’re looking for a free WordPress cache plugin that is reliable and comes with a premium version. What makes this tool unique from some of the other options, such as WP Rocket, is that it only requires a one-time fee for the premium version rather than an annual subscription.

Price: Free, with premium licenses starting at $49.99 | More Information

5. Comet Cache

The Comet Cache WordPress plugin.

Comet Cache is a freemium WordPress cache plugin that can help enhance the speed of your website with just a few simple clicks. While it doesn’t have nearly as many active installations as most of the tools on this list, it’s still a solution worth checking out.

After installing Comet Cache you can enable or disable caching, and then browse through the settings panels to configure the plugin to your liking:

The interface is a bite more user-friendly than some of the basic checkboxes you’ll find with alternative plugins. It is relatively organized, and makes finding the specific settings you need easy.

Key Features:

  • Automatic cache clearing
  • Client-side caching
  • Simple configuration with support documentation
  • GZIP compression

Comet Cache is for you if…

… you’re looking for a freemium plugin that provides clear, simple settings. Not only can you preview the pro features directly from your WordPress dashboard via the free plugin, but you can also choose from three pricing plans.

Cache Enabler is a simple WordPress cache plugin that is powered by KeyCDN, a high-performance content delivery network. Unlike some of the other options on this list, it doesn’t overwhelm you with too many settings or bells and whistles:

  1. Yo guys forget fhe allerbest one.

    Swift performance!

    • You are joking right?
      Read the reviews… seems like a no brainer to me.

    • Thanks for the suggestion!

  2. Nice little piece of information there, Will.

    Few points:
    1. I think you should definitely include Litespeed Cache in this list. It is a highly rated plugin and is comparable with the top 3 any day. It is fine tuned for Litespeed which most servers deploy these days.
    2. WP Rocket is a completely premium plugin, hence not available in WordPress repository. The lazy load plugin you mentioned is different from the caching plugin, although they are from the same developers. So, calling it “Free, with premium licenses…” is kind of misleading.

    Also, you might want to check out WP-Optimize. They have added caching/minifying functionality which work well until now. Given it is already well-known, there’s some good potential I see.

    Anyway keep up the good work.

    • I appreciate the detailed input – thanks for sharing your thoughts!

  3. I can assure none of above is as good as this new plugin named docket cache. Please try & review it.

    • We’ll check it out 🙂

  4. I read that you need to disable Divi’s minification and caching when using a caching plugin because, the caching plugin will cache Divi’s cached & minified files (styles, java, etc) and not update them when Divi updates them.

    Is this correct? Any thoughts on Hummingbird? They recently posted a blog article on using their plugin to optimize Divi.

    Are the plugins you mentioned above sponsors of Divi or yourself or are you affiliates of them (ie, do you get a kickback when someone follows your links)?

    • Thanks for the response – I’d suggest checking in with the Elegant Themes support team directly regarding these questions.

  5. What about NitroPack?

    • It didn’t quite make our list due to its overall ratings, but it’s an option worth checking out 🙂

  6. Hi,
    Thanks for the nice and updated article. What about the LiteSpeed Cache? Can you compare it too with the mentioned plugins?

    • You’re welcome! From what I know that plugin is an excellent option as well 🙂

  7. This is just the list that I was looking for. I didn’t know about half of these Plugins. I’ve personally used NitroPack for a while now, since other Plugins that I have tried didn’t really work for me, but I will definitely look at these options to see if I enjoy using them too.

  8. W3 Total Cache work excellent for me never thought about using others. But one should always have a choice. Thanks for sharing 🙂

  9. U can also try lscache caching plugin for wp speed optimization.
