LiteSpeed Cache vs WP Rocket Similar Features:

Although LiteSpeed Cache and WP Rocket are two different plugins from two different companies and a variety of different developers but they both are trying to achieve same results. Since both of these are cache plugins, let’s talk about similar features first.

  1. Both WP Rocket and LiteSpeed cache provides full pages caching.
  2. Caching process is almost same.
  3. Purge process is same.


Both plugins are able to do full-page caching. Rather than waiting for WordPress and PHP to assemble the pages with every request, a page cache can provide the snapshots much faster.

Caching with WP Rocket:

Like all cache plugins, WP Rocket also uses .htaccess rewrite rules to tell the server where the cached content is present. WP Rocket puts pages into the file system for caching, then removes them from there for purging (purging can be triggered by various methods one of which is TTL expired). That way, caching and purging work together. In this case, it examines the cache file system to see if the page exists. If it does not, then it is not cached. It can also tell if a cached page has expired by comparing the file time with the TTL.

Caching with LiteSpeed:

LiteSpeed Cache and WP Rocket cache content in a similar way but their main difference is the server-level caching module. LSCache is not doing the caching but rather the caching is handled by LiteSpeed web server cache module. Litespeed cache can be seen as a bridge between the user and caching module. It only gives an easy way for the webserver to perform functions such as adding and removing files from the cache.


The big difference between LSCache and WP Rocket is the pricing.

WP Rocket is a totally paid plugin its price start from $49/year. They only provide you with 14 days money-back guarantee and you can check the pricing.

On the other hand, LSCache is a totally free plugin. You can install it on your site and use it without paying anything. But for the server-level cache, you must have a LiteSpeed Webserver on your host or you can use OpenLiteSpeed with CloudPages. You can get LiteSpeed Ent from here.

You can deploy both stacks on CloudPages (for LiteSpeed Enterprise, you can purchase license from LiteSpeed store)

eCommerce + ESI:

Some pages should not be cached for online shops and stores. For example, you do not want the cart and some widgets to be cached.

When you install WP Rocket on your online store, the cart and checkout pages are automatically not cached. They are dynamically generated and served without caching.

The LiteSpeed cache plugin comes up with a caching solution for eCommerce pages. With Edge Side Include (ESI), the pages are cached in LSCache. A hole is punched in public pages containing shopping cart data and other private content using ESI. The mixed-content page can then be fully cached and served to shoppers.

Ease of Use:

For Ease of Use: WP Rocket wins.

WP Rocket does not confuse users with lots of options to configure. However, LSCache plugin gives lots of options to users and newbies get overwhelmed.

As a developer you may enjoy LSCache more as it gives you freedom to configure everything.

LSCache vs WP Rocket: Features Comparison:

Now let’s talk about some features of LSCache and WPRocket and see which features are present in both or missing from both or one of them.

Cache Features:

Despite having many features in common, both plugins have some key differences. The following features were taken from the plugin’s official sites and guides and compared between the two.

Tag-Based “Smart Purge” : Not many people are familiar with cache purge. With any cache solution intelligent purge is really important, otherwise your visitors might be getting outdated content.

LSCache wins in this department and that is why it is really loved by WordPress community. LSCache cache each page with tags and whenever any of those tags expires the whole page is taken out from cache and rebuilt and saved in cache engine.

QUIC Cloud CDN Services by LSCache Plugin:

QUIC.Cloud CDN is an intelligent full-page caching CDN from LiteSpeed Technologies which runs on top of the LiteSpeed cache plugin in WordPress. It is the only CDN that can accurately cache dynamic pages, or pages which features content that quickly changes.

LiteSpeed cache for WordPress knows when it needs to automatically purge and sync data in the CDN, giving it the upper hand over other providers, like Bunny CDN and Cloudflare.

QUIC.Cloud also has some handy features, including

  1. Image optimization
  2. Critical CSS support
  3. LQIP or low quality image placeholder support

Another important thing about QUIC.Cloud is that its totally free to use.

QUIC.Cloud gives its users a certain amount of credit for each of their tiers of service. there are four service tiers.

  1. “Basic” which receives 10 credits
  2. “LiteSpeed server” which receives 50 credits
  3. “LiteSpeed Enterprise” which receives 100 credits
  4. “QUIC.Cloud partner” which receives 200 credits

For their CDN service specifically, each GB can “cost” you between 10 to 40 credits per GB of transfer for other services offered by QUIC, such as Image Optimization, there are other limits, which are similar to the way the CDN tiers work.

How does QUIC.Cloud compare to Cloudflare

Static vs Dynamic Caching

Cloudflare is an extremely popular CDN and DNS service provider, so popular that over 20 million websites are running the service. Their free CDN service focuses primarily on accelerating static resources such as images, CSS, JS, etc. and is platform agnostic, meaning it works with straight HTML, WordPress, Joomla, Drupal and other platforms.

QUIC.Cloud on the other hand is a new service from LiteSpeed Technologies which integrates directly into WordPress and accurately caches dynamic pages, or page which features content that quickly changes in your WordPress site.

Number of POPs

The biggest difference in terms of CDN in QUIC verses Cloudflare is the total number of available Points of Presence, PoPs. These are the individual data centers from where CDN providers can deliver content to visitors of sites using their services in those area of the world.

Because its relatively new, QUIC only have a little over 40 PoPs around the world, which is still very large for a new provider. But compare to Cloudflare on the other hand which has over 200 PoPs. Cloudflare has an unmatched advantage for faster delivery of static content anywhere in the world. However, keep in mind that Cloudflare doesn’t offer dynamic content caching for for free. For that you have to stop to their automatic platform optimization (APO) plan, which carries minimal monthly fee.

QUIC Cloud Full Page WordPress Caching

QUIC.Cloud only works with WordPress websites, at least for now and the only way to use QUIC.Cloud is from the LiteSped Cache for WordPress plugin. As you can surmise, this is a complete optimization solution for WordPress. From optimizing everything is WordPress using the LiteSpees Cache plugin, to delivering those optimized files using the QUIC CDN, LiteSpeed technologies have really built a tightly integrated platform.

Additional Services: CSS, JS Minification and optmizations

With QUIC.Cloud you get everything needed to optimize WordPress sites like modification, combination, image optimization, critical CSS generation, server push, a sync, defer and alot of other optimizations. This gives QUIC.Cloud an unmatched edge over Cloudflare that isn’t specifically optimized for WordPress sites but for every type of website as a whole.

Though Cloudflare does minification, image optimization and some other optimizations from their CDN, they are not tailored towards WordPress WordPress sites and so lacks lot of the features that are offered in QUIC.Cloud and LiteSpeed setup.

LSCache plugin and Cloudflare

You can, however use LiteSpeed Cache together with Cloudflare which will allow you to use all the optimizations offered by QUIC.Cloud with the CDN of CloudFlare. In short best of both worlds.

But if you choose this dual service method, you won’t get the seamless integration between WordPress and CDN that is provided by QUIC.Cloud and LiteSpeed Cache.

For instance, if LiteSpeed Cache purges its cache QUIC.Cloud CDN will also purge its cache.

LSCache + QUIC Cloud

In fact, almost all the settings of QUIC.Cloud are located inside the LiteSpeed Cache plugin and not in the QUIC.Cloud dashboard. So, you won’t ever need to worry about managing your WordPress and CDN separately which can’t be said for any other providers.

Though CloudFlare provides automatic cache purging, dynamic caching with cache bypass on cookies and some other features that try to make WordPress and CDN work together, the integration of QUIC.Cloud with LiteSpeed Cache is something totally different and should be called its own app ecosystem.
