11 Best WordPress Caching Plugins Compared (2022)

Best WordPress Caching Plugins

Do you want to increase the speed of your WordPress website? Using a caching plugin on your website is one of the best ways to ensure your website loads faster.

Statistically speaking, nearly half of your website’s audience expects your site to load in less than 3 seconds. So it comes as no surprise that Google continues to emphasize site speed in its search algorithm. The higher the page speed, the better your search rankings, and the more organic traffic you can attract.

In this article, we will share the best WordPress caching plugins for your website.

Why Do You Need a WordPress Caching Plugin?

A caching plugin generates static HTML pages of your website and saves it on your server.

Each time a user tries to access your website, your caching plugin serves up the lighter HTML page instead of processing the comparatively heavier WordPress PHP scripts. This allows the caching plugin to tremendously improve your page loading time.

With caching plugins, you can:

  • Increase your website’s speed and reduce page load time
  • Improve user experience as everything works faster and smoother
  • Boost SEO rankings as search engines love a fast loading site

Caching plugins handle all the technical work while you just have to click a few buttons to make your site incredibly faster. Now, let’s dive into the best caching plugins for WordPress.

  • WP Super Caching: This method is used to cache pages for known users (the ones who log into your site, leave comments, etc.). Though it’s the most flexible caching method, it’s slightly slower compared to other methods.

You can also serve all cached files on your site from the content delivery network (CDN) of your choice. It supports popular CDN networks like CloudFront, MaxCDN, and more.

To avoid generating a new version of the cache while your server is busy, the plugin monitors the server load and temporarily disables cache expiration.

Hyper Cache is a caching plugin purely written in PHP that can be used in both cheap hosting environments as well as high end servers.

Activating Hyper Cache is easy because it works with a set of default values.

The plugin comes with a mobile theme switch option that allows you to enable caching even if you’re using different layouts for mobile users and desktops. This comes in handy if you use a responsive theme on your site or need different ad formats for different devices.

Another unique benefit of Hyper Cache is its ability to serve cached pages to comment authors. However, you can also disable serving cached pages to comment authors if you want to.

It is also a bbPress ready plugin, so you can enable cache for your bbPress forum pages.

The downside to this plugin is that it hasn’t been updated in a really long time nor has it been tested with the latest 3 major releases of WordPress. We would recommend looking for a plugin that is better maintained.

    Which one do you think is the best cache plugin which covers all the feature i.e. one in all.

    1. Each plugin has its unique features. You should read our conclusion to understand which software is best for you!

  2. I’m surprised the Litespeed cache plugin isn’t included in this list (aware that not all servers are litespeed but SG Optimizer is in the list, sooo).
    While these are very good cache plugins they all have their drawbacks which can make them an undesirable choice. For instance, WP Rocket, consistently regarded as the best has purge rules which simply do not work for busy blogs and e-commerce stores. It will clear the entire cache when a sale comes in, when a comment or review is published, when a post is published and so on. This can lead to fewer cached pages and increased server load. Litespeed has finer control over cache purge rules meaning the entire site performs better.

    On top of the purge rules that are far more superior it’s also packed with features that the others simply don’t have. These are lazy load, image optimisation with webp and much more.

    I have used most of the plugins in this list and if I can’t use Litespeed I will revert reluctantly to WP Rocket.

  3. The plugin WP Fastest Cache tells you to install the plugin WP-Optimize for part of its recommendations. Aren’t they basically the same plugin, so can’t I delete WP Fastest Cache and just keep WP-Optimize? Thanks!

  4. what about Litespeed cache?

  5. I wonder which one is the best for a multisite?

  6. Thanks for sharing this collection of plugins with us. It’s really awesome article.

  7. Autoptimize loads my site a whole lot faster than WP Rocket. Performance score 99% but using WPR 86%

  8. Does it work with WP Fastest Cache

  9. What are you thoughts about LiteSpeed Cache? My wordpress came with that plugin. Should I change to a different cache plugin?

    1. Looks like it’s a good plugin but I’ve never tried it yet.

    2. You need Litespeed server for it to work 100%

    3. Litespeed Cache plugin is great…especially at no charge there are a ton of options. I have my site using it and it went from 2.4 seconds load speed with 86 PageLoad speed to 1.4 seconds with 99% Pageload speed according to GT Metrix. I recommend it. The only thing I noticed is under the Litespeed Cache–>Settings–>Optimize if you enable CSS Combine, your site fonts get changed with something random like Times New Roman (at least on my site it did), so I chose not to enable Combine CSS. Other than that, I have no complaints about it at all.


    1. Shahzad Saeed July 17, 2019 at 6:13 am

      Thanks! I just updated the post.

  11. Thankss for this really nice info.

  12. Why you did not mention LiteSpeed Cache Plugin. It’s free and comes with more feature including image optimization.

  13. Shahriar Islam June 6, 2019 at 5:48 am

    You should try LSCache for more faster site load.

    1. yes correct but not support every hosting company. they are argue “OpenLite speed and the Apache are 2 different types of webserver. and we not provide OpenLite speed in this plan. however you can upgrade to get this benefit”.

      So its hopeless in this current plan.

  14. I am trying to recover from my own issues with multiple sites being hacked, so your post is timely and appreciated.
    When I ran the WP Security Scan tool, one of the things that it noted is that an htaccess file did not exist in my wp-admin directory.
    I couldn’t find any documentation in the tool to explain what this file should contain though.
    Can this contain some basic information, or is it something that should be customized to each site?Any recommendations on this step would be greatly appreciated.

  15. Thank You for your review….

  16. Any cache list that doesn’t include Borlabs Cache and Swift Performance WordPress Cache is highly suspect!

    1. I think there is much better free cache plugins out there, but Swift Performance should be mentioned.

      1. Thanks for stopping by Bryant and Gary.

    2. Agree. Specially for Borlabs

  17. Have you compared them to LiteSpeed’s LSCache? It’s getting pretty popular, especially for WordPress users 🙂

    1. Didn’t test it yet but thanks for the addition, Kacey!

  18. You forgot to mention Autoptimize, a plugin recommended by Google Optimization Experts in many cases.

    1. Yup!
      That’s a great addition to the list, Patrik. Thanks for stopping by 🙂

      1. Is there any other way to make your website’s loading time faster ? instead of caching it ?

        1. Take a look at this article for speeding up your website.
