📅 Updated October 2026 Versions and prices in this guide come from LiteSpeed's official pages and release log, the plugin's page on WordPress.org, W3Techs and Wordfence, all read on October 12, 2026.

Almost every host puts the word LiteSpeed at the top of its page, and few customers know what they are actually buying. Is it a server? A caching system? A WordPress plugin? The answer is all three, and each one is a different thing. Mixing up these names is behind most of the questions we get on the subject.

In this guide we separate the names, explain the difference between OpenLiteSpeed and LiteSpeed Enterprise, what happens inside the server when you turn on LSCache, and how LiteSpeed works with cPanel, Plesk, DirectAdmin and CyberPanel. At the end there are practical steps to confirm that your site really benefits from it. If the idea of a web server itself is not clear yet, read that explainer first and come back.

The short version, in three lines:
  • LiteSpeed Web Server: a web server that replaces Apache and reads your Apache configuration as it is.
  • LSCache: a page-cache engine built into the server itself, not inside PHP.
  • The LiteSpeed Cache plugin: a free WordPress interface that controls that cache. Its cache features need a LiteSpeed server, while its image and file optimization tools work on any server.

What is LiteSpeed Web Server?

LiteSpeed Web Server (LSWS for short) is web server software developed by LiteSpeed Technologies. It does the same job as Apache and Nginx: it receives the browser's request, serves the page and files to the visitor, and passes PHP files to the processor. What sets it apart is that it was built to replace Apache without you changing anything in your setup, because it reads Apache's configuration files and the .htaccess rules that already exist.

So when you buy web hosting from a company that says it runs on LiteSpeed, it means that its servers run this software instead of Apache, not that you get a separate product you pay for.

A quick history

LiteSpeed was released officially as a full web server on July 1, 2003. In 2007 it became LiteSpeed Web Server Enterprise, set up as a direct replacement for Apache. It supported HTTP/2 in 2015 with version 5.0, and version 5.0.10 brought the first LSCache for WordPress, with ESI support. HTTP/3 came with version 6.0 in March 2021 and was turned on by default in 6.0.2, and version 6.2 added QUIC v2 support in December 2023.

Where does it stand in 2026?

The latest stable version when this was written is 6.3.7, dated September 23, 2026, according to the official release log. It is a security-focused release: it locks down lscgid further, tightens validation of lscgid requests and of internal redirect URLs, blocks internal environment variables from .htaccess files, and turns on post-quantum key exchange. Version 6.4 is still at release candidate 2 (RC2), and its first candidate added Zstandard compression, background cache refresh and a new interface for the WebAdmin console. We would not advise a server administrator to put it on a production server before its stable release.

This year has not been free of sensitive fixes. Version 6.3.5, dated March 14, 2026, fixed remotely exploitable flaws in the HTTP/3 engine and added extra sanitizing of external application commands to address CVE-2026-31386. The point for you as a customer is that a host's quality does not stop at using LiteSpeed; it depends on whether the host keeps it updated.

On reach, W3Techs says LiteSpeed is used by 14.1% of all the websites whose web server it knows (October 2026).

How does LiteSpeed work, and why is it different from Apache and Nginx?

An event-driven architecture

In the setup commonly used on shared hosting, Apache gives roughly one process or thread to each connection, so memory use balloons as visitors increase. LiteSpeed uses an event-driven architecture instead, in which a few processes handle thousands of open connections at once without reserving separate resources for each one. That is why it can serve a large number of simultaneous visitors with less memory and processor use.

But Nginx works on the same principle. The real difference between LiteSpeed and Nginx is not the architecture but two things: full compatibility with Apache, and the cache built into the server. We explain both in the next sections.

Full compatibility with Apache configuration

LiteSpeed can load Apache configuration files directly, and it supports the rewrite engine and ModSecurity rules. That is why a host can move from Apache to LiteSpeed without customers noticing any change in their sites. That alone drove its spread on shared hosting built on cPanel, because nobody wants to rewrite thousands of .htaccess files.

Security, isolation and compression

Version 6.3, released in June 2024, added a set of features aimed at shared hosting: resource limits for external applications through cgroups, file-system isolation through namespace containers, advanced anti-DDoS protection against request flooding, a firewall controller that blocks detected bots, and easy detection of a front-end CDN (QUIC.cloud or Cloudflare). The server also supports CAPTCHA challenges (reCAPTCHA, with ALTCHA added in the 6.4 release candidates) and, since version 6.3.6, automatically blocks requests for /.env URLs.

On performance, LiteSpeed supports Brotli compression and will add Zstandard in version 6.4. Good compression cuts the size of the responses that are sent, which eases bandwidth use and speeds up loading on slow networks.

HTTP/3 built in

LiteSpeed supports HTTP/3 over QUIC through LSQUIC, an open-source library the company develops and uses in LiteSpeed Web Server, OpenLiteSpeed and Web ADC. The practical benefit shows more on unreliable mobile networks, where the connection recovers from lost packets faster than with HTTP/2.

LiteSpeed editions: OpenLiteSpeed or LiteSpeed Enterprise?

The name LiteSpeed covers two products that share the same engine but differ in license and in how they integrate with control panels. This table sets them side by side:

Feature OpenLiteSpeed LiteSpeed Enterprise
License Free and open source Commercial, with a license (and a limited free tier)
.htaccess rules Only rewrite rules are read, and a change needs a restart Apache directives are read on the fly with no restart, a direct replacement for Apache
cPanel and Plesk No official integration Official integration through plugins
LSCache Yes, through the cache module Yes, included in the license
ESI Not supported Supported
Support Community and forums Official support from the company
Best for VPS servers with panels such as CyberPanel and Enhance, or with no panel Any server running cPanel, Plesk or DirectAdmin

The practical conclusion: if the server runs cPanel or Plesk, the officially supported choice is Enterprise alone. If you manage a VPS yourself with no panel, or with a panel built around LiteSpeed, OpenLiteSpeed is enough for most sites, and it is the cheapest option by definition because it is free. The two are normally not installed side by side on the same server, so choose before you install.

LiteSpeed also sells a third product, Web ADC, a load balancer that starts at $65 a month to lease ($1,299 to own) and keeps the cache at its own level in setups with several servers. Most readers will not need it.

How much does a LiteSpeed Enterprise license cost?

This question is not yours if you are a shared hosting customer, because the host pays. But it matters if you buy a VPS and want to install LiteSpeed yourself. The prices below come from the official pricing page as read on October 12, 2026, in US dollars:

Plan Domains Memory Workers Monthly Yearly
Free Starter 1 Under 2 GB 1 Free Free
Site Owner 5 Under 8 GB 1 $10 $110
Site Owner Plus 5 Unlimited 1 $16 $176
Web Host Lite Unlimited Under 8 GB 1 $26 $286
Web Host Essential Unlimited Unlimited 1 $36 $396
Web Host Professional ⭐ Unlimited Unlimited 2 $46 $506
Web Host Enterprise Unlimited Unlimited 4 $65 $715
Web Host Elite Unlimited Unlimited X (set by the license) $92 $1,012

Plans from Professional up add Listener Binding, and the Elite plan adds protection against DDoS attacks. One-time licenses start at $464 for Web Host Lite and reach $1,999 for Elite, with an upgrade fee of $79 to $449 a year after the first year. Yearly plans include one month free, and LiteSpeed offers a 15-day free trial.

⚠️ Watch the domain limit: the limit counts top-level domains only. Subdomains, and aliased or parked domains that do not use their own virtual host, are not counted. If you exceed the allowed number, 403 errors appear, and in control panel environments the server reverts to Apache automatically. If your site on a VPS suddenly switches to Apache after you add new domains, this is the first thing to check.

What is LSCache?

LSCache (short for LiteSpeed Cache) is a page-cache module built into the LiteSpeed server itself, not a plugin that runs inside PHP. That is the fundamental difference. A traditional caching plugin works after WordPress has started loading, while LSCache catches the request at the server layer and returns the saved page before PHP or the database is called at all.

What happens on the first visit and after?

Stage Without a page cache First visit (cache miss) Later visits (cache hit)
Who builds the page? PHP on every visit PHP once Nobody; the saved page is served
The database Queries on every visit Queries once No queries
Where is the page stored? Not stored In the server's cache Read from the server's cache
Response header None x-litespeed-cache: miss x-litespeed-cache: hit

The cached pages themselves live in the server's cache storage, not in your WordPress folders, which is why you do not see page-cache files in the wp-content folder the way you do with other plugins (the plugin can still keep some optimized files there).

Smart purging with tags

The hardest part of any cache is clearing it at the right time. LSCache solves this with tags: the plugin attaches tags describing the content to each response, so when you edit an article or a product the server clears only the pages related to it, and you do not have to clear the whole cache by hand every time. It can also serve different versions of the same page according to cookies (vary cookies), such as mobile vs desktop or different currencies.

Logged-in users and ESI

A public cache does not suit a page that shows the user's name or the contents of a shopping cart. That is where the private cache for account holders comes in, and ESI (Edge Side Includes), which punches a hole in the saved page and leaves a small part of it to be built live, such as the cart piece or security tokens (nonces). You should know that ESI is not available in OpenLiteSpeed, which is one reason Enterprise is preferred for stores.

The difference between similar names

This is where most of the confusion happens: six similar-looking names, each a different thing:

Term What it actually is Where it runs Cost
LiteSpeed Web Server (LSWS) A commercial web server that replaces Apache On the server Licensed, with a limited free tier
OpenLiteSpeed (OLS) The open-source edition of the server On the server Free
LSCache The page-cache engine inside the server Inside LSWS or OLS Included in the license
LiteSpeed Cache plugin A WordPress interface that controls the cache and adds optimization tools Inside WordPress Free and open source
QUIC.cloud A CDN and cloud services (images, critical CSS) LiteSpeed's cloud A free allowance, then paid
LiteSpeed Web ADC A load balancer between several servers On a separate server Paid, from $65 a month

The LiteSpeed Cache plugin for WordPress: what it offers and where it stops

The plugin is the interface that controls LSCache from inside the WordPress dashboard. It is among the most widely installed plugins: more than 7 million active installations and a 4.8 rating on its WordPress.org page. The current version, 7.9.1, was released on September 1, 2026, and requires WordPress 6.0 or later and PHP 7.4 or later. Its changelog lists version 8.0, titled OptiMax, as "coming soon" for 2026.

The rule that explains half of readers' questions

The plugin is always free, but its features are of two kinds: optimization features that work on any server, and cache features that need a LiteSpeed server (or OpenLiteSpeed, or the QUIC.cloud service). Anyone who installs it on Apache or Nginx gets the optimization tools only and will not see the page cache work.

Works on any server Needs a LiteSpeed server
Image optimization (lossy or lossless compression) with WebP and AVIF formats
Minifying and combining CSS, JavaScript and HTML files
Automatic Critical CSS generation
Lazy loading for images and iframes
Asynchronous CSS loading and deferred JS
Database cleaner
Heartbeat control and DNS prefetch
Compatibility with an object cache (Redis or Memcached)
Automatic page cache
Automatic purging of related pages when you edit
Private cache for logged-in users
REST API cache
Separate mobile and desktop cache
A crawler that warms the cache through the sitemap
WooCommerce and bbPress support
WP-CLI commands and ESI

Note that an object cache is not a service the plugin provides itself; it works with one if your host installs it. Do not assume it is on by default.

QUIC.cloud: the part marketing does not mention

QUIC.cloud is the cloud service tied to the plugin, offering a CDN, image optimization and critical CSS generation. It also lets sites on Apache or Nginx benefit from LiteSpeed's cache through the CDN. Some of its services are free up to a usage limit and then become paid, and the limits show in your account on QUIC.cloud.

The side that many overlook is privacy: when you use image or page optimization, your site's data (not your visitors' data) is sent to QUIC.cloud servers to be processed. Its privacy policy says it keeps the optimized copies of images and CSS for seven days and then permanently deletes them, and that these features do not collect visitor data, although access and error logs on its nodes can record visitor IP addresses and the URLs visited. If you use Cloudflare in front of your site, the server recognizes its addresses automatically, but do not run two CDN layers that compete to cache the same page until you understand what each one does.

A security history you should know

⚠️ The plugin does not have a clean security record, and updating it is not optional: Wordfence lists CVE-2024-28000, an unauthenticated privilege escalation rated 9.8 out of 10 that affected versions up to 6.3.0.1 (patched in August 2024), followed by CVE-2024-50550, another unauthenticated privilege escalation rated 8.1, in October 2024. Its database also shows five entries between May and September 2026, four of them cross-site scripting and one an unauthenticated server-side request forgery rated 7.2, all marked patched, the newest affecting versions up to 7.9 (the current release is 7.9.1). This does not mean you should avoid the plugin, because any plugin this widely used is examined heavily and fixed, but it does mean keeping it updated and making sure your host does not freeze an old version of it.

LSCache is not only for WordPress

There are official LSCache plugins for Magento, Joomla, PrestaShop, OpenCart, Drupal, XenForo, Laravel, Shopware, MediaWiki and Django. If your site runs one of these systems and your host runs LiteSpeed, the same logic applies: the server stores, and the plugin tells it what to store and when to clear it.

Which hosts offer LiteSpeed ready to use?

Hostinger's web hosting page says its plans run on LiteSpeed servers, GreenGeeks lists LiteSpeed caching technology (LSCache) on its shared hosting, and ScalaHosting's VPS page lists OpenLiteSpeed with the LiteSpeed Cache plugin, plus LiteSpeed Enterprise add-ons, on VPS plans that use its SPanel. Still, check the plan page before you buy, because some companies limit LiteSpeed to particular plans and do not offer it on every package.

LiteSpeed support in control panels: cPanel, Plesk, DirectAdmin and others

LiteSpeed's commercial strength is that it replaces Apache without breaking the control panel. But the word "supports" means something different in each panel: in one it is an official plugin supported by the panel's developer, in another an installer that runs alongside the existing web server, and in a third the panel itself is built around LiteSpeed. This table summarizes the picture, and the key details follow it.

Panel Type of support Suitable edition Where you manage it
cPanel/WHM A LiteSpeed plugin for WHM; LiteSpeed's docs say the cPanel, LiteSpeed and CloudLinux combination is officially supported by all three companies Enterprise WHM, then Plugins, then the LiteSpeed Web Server plugin
Plesk The official LiteSpeed installer, with regular fixes for WP Toolkit compatibility Enterprise WebAdmin Console
DirectAdmin Integration through the installer, with its own PHP handler (lsphp) Enterprise Extra Features
CyberPanel A panel built around LiteSpeed OpenLiteSpeed (free) or Enterprise From inside the panel
Enhance Supports both editions, with LSCache turned on by default Enterprise or OpenLiteSpeed From the Enhance panel
InterWorx Supports LiteSpeed Web Server out of the box, according to LiteSpeed's docs LiteSpeed Web Server See InterWorx's documentation
SPanel (ScalaHosting) OpenLiteSpeed and the LiteSpeed Cache plugin on its VPS plans, with LiteSpeed Enterprise sold as an add-on OpenLiteSpeed or Enterprise As listed on ScalaHosting's VPS page
hPanel (Hostinger) The company's own panel, on LiteSpeed servers Chosen by the host You do not manage it

cPanel and WHM: the most complete integration on the market

If you have not met it yet, cPanel is the best-known control panel on shared hosting, and also the one that integrates best with LiteSpeed. The official WHM plugin gives the server administrator:

  • Installation with one command: an automatic install script that sets up LiteSpeed and the plugin together, and you can choose WHM as the panel during installation from the command line.
  • One-click switching between Apache and LiteSpeed without downtime, with the option of running LiteSpeed on a different port (a port offset) to test sites before the real switch.
  • Automatic PHP setup: it rebuilds LSPHP automatically when EasyApache settings change, and prepares PHP suEXEC and the cache with fast settings.
  • Bulk cache management: from the Manage Cache Installations section the plugin scans every WordPress installation in the users' accounts, then turns the cache on for them in one go and installs the LiteSpeed Cache plugin automatically.

For the end customer, an icon called LiteSpeed Web Cache Manager appears under the Advanced section of their cPanel after the server administrator installs the companion cPanel plugin (and adds it to the account's feature list). One practical caution: because the LiteSpeed Cache plugin remains an ordinary WordPress plugin, any user with admin rights can delete or deactivate it without the server administrator knowing.

⚠️ A note for hosting customers: a LiteSpeed license has a domain limit, as we saw, and in a cPanel environment if the limit is exceeded the server reverts to Apache automatically. If your site suddenly shows no server: LiteSpeed header, ask support about the server's license before you change any setting of your own.

Plesk and DirectAdmin

LiteSpeed's official installer is tested with cPanel, Plesk and DirectAdmin, and on cPanel and Plesk it offers to run LiteSpeed alongside the existing web server and then switch between the two without downtime. The release log shows repeated Plesk compatibility fixes (a systemd service override, WebSocket upgrades and WP Toolkit hotlink rules). The frequency of those fixes is a sign of active support, and a reminder that compatibility with a panel that keeps changing needs a host that follows the updates.

In DirectAdmin you reach the WebAdmin Console from the Extra Features section once installation finishes, and using lsphp as the PHP handler is advised. Version 6.3.4 fixed problems with Roundcube mail on DirectAdmin, which shows that support exists but needs follow-up.

CyberPanel, Enhance and others: panels built around LiteSpeed

CyberPanel is the one panel originally built around LiteSpeed. Its free edition uses OpenLiteSpeed and its Enterprise edition uses LiteSpeed Enterprise, and LiteSpeed sells a bundled license with it in its shop. Its problem is not technical but about reach: its community is smaller than cPanel's and hosting companies' support for it is limited.

Enhance is a modern, containerized panel that supports LiteSpeed and OpenLiteSpeed, turns the LSCache module on by default and includes a WordPress toolkit for plugin management. For anyone who wants to try LiteSpeed on a VPS without committing to a cPanel license, UltaHost lists CyberPanel among its free VPS panels, and Contabo gives you a VPS where you install whatever you like, such as OpenLiteSpeed, yourself.

How do you confirm your site runs on LiteSpeed and turn on LSCache, step by step

The steps below are for a WordPress site owner on shared hosting, and they do not need access to the server itself.

1
Check the response header: open your site in Chrome, press F12, open the Network tab, refresh the page, click the first request (named after your domain) and look at the Response Headers. If you find server: LiteSpeed, your host is already running it. If the name Cloudflare appears instead, a CDN layer in front of the server is hiding the truth, so look for any header that starts with x-litespeed or ask support. You can also check with one command from the terminal:
curl -I https://yoursite.com
An example of the server: LiteSpeed response header in the Network tab of the developer tools
An example of the server: LiteSpeed response header in the Network tab of the developer tools
2
Install the plugin: from the WordPress dashboard go to Plugins, then Add New, search for LiteSpeed Cache (from LiteSpeed Technologies), then click Install and Activate.
3
Turn on the cache: from the LiteSpeed Cache menu choose Cache and make sure Enable LiteSpeed Cache is ON. If the option does not work even though your host is on LiteSpeed, the server administrator may not have set the cache root yet, and you ask support for that.
Turning on the Enable Cache option in the LiteSpeed Cache plugin settings
Turning on the Enable Cache option in the LiteSpeed Cache plugin settings
4
Start with a moderate setup: do not turn on every option you see. Open the Presets menu and start with a moderate ready-made setting (such as Basic or Advanced), then test your site before you add more.
5
Turn off any other page cache: if you have WP Rocket, W3 Total Cache or any other page-cache plugin, turn off its page-caching feature. Running two caches for the same page does not double the speed; it creates conflicts that are hard to trace.
6
Check that the cache works: open the site in a private (Incognito) window and refresh the page twice, then look at the same header. On the second request you should see x-litespeed-cache: hit, while the first may show miss, which is normal.
7
Test the sensitive pages: try the cart, the My Account page, the checkout and your contact forms, both logged in and logged out. If a page should not be cached, exclude it from the Excludes tab on the Cache page.
💡 If you are the cPanel server administrator: to turn the cache on for many WordPress sites at once, log in to WHM, open the LiteSpeed Web Server plugin, go to Manage Cache Installations (or use Mass Enable Cache), and enable the cache on the sites you choose. The plugin can install the LiteSpeed Cache plugin on the selected sites for you.

Common mistakes that waste LSCache's benefit

Turning on CSS and JS combining and deferring all at once. These options change your site's files and can break the menu, the forms or the slider. Turn on one option at a time and test after each, and do it on a staging copy first if the site makes money.

Assuming images improve on their own. Image optimization does not run automatically unless you turn on the automatic request option (Auto Request Cron), or request optimization by hand from the Image Optimization tab.

Forgetting that the crawler is off by default. The crawler warms the cache after every purge, and the server administrator has to enable it first before you can turn it on from the plugin.

Not testing the dynamic parts. The cache treats an ordinary visitor and a logged-in user differently (public, private and ESI). If you run a store or a membership site, check after turning it on that the user name and the cart show correctly, and read LiteSpeed's documentation before you change the private cache settings.

Neglecting WooCommerce. The store is officially supported, but LiteSpeed's own documentation warns that some themes do not update the cart correctly with the cache on, so it needs testing.

Is LiteSpeed really faster? A frank comparison with Apache and Nginx

The fair answer is that no single comparison settles it, and we have not benchmarked these servers ourselves. What can be said from how they work is that much of LiteSpeed's advantage for PHP sites such as WordPress comes from the cache built into the server, not from the server alone.

Criterion Apache Nginx LiteSpeed
Architecture Processes and threads in the common setup Event-driven Event-driven
.htaccess files Supported natively Not supported Compatible (instant in Enterprise)
Page cache Through modules or plugins FastCGI cache, needs configuration Built-in LSCache, with ready-made plugins for many systems
Shared hosting The original and most common Less common Official plugins for cPanel, Plesk and DirectAdmin
Cost Free Free Free (OpenLiteSpeed) or licensed (Enterprise)

Comparisons that put an uncached site on Apache against a fully cached one on LiteSpeed measure the cache, not the server, so be wary of numbers claiming it is dozens of times faster. A fair comparison runs each server with its own best cache, and then the gap narrows. Two practical advantages remain for LiteSpeed: it needs no complicated cache setup with WordPress, and it does not ask you to give up .htaccess. In every case no server will fix a bloated theme, huge images or dozens of heavy plugins.

🎯 Who should care about LiteSpeed, and who will not notice much?

✅ It matters to you if:

  • Your site is WordPress or WooCommerce on shared hosting
  • You want a cache that works with few settings and no server-tuning experience
  • You run a VPS and want better performance than Apache while keeping your .htaccess files
  • You work on cPanel, Plesk or DirectAdmin and want official integration
  • You run several sites and want to set the cache for all of them from one panel

❌ It changes little if:

  • Your site is static with no PHP, so the cache adds little
  • You use a managed platform with its own infrastructure and cache, such as Kinsta
  • Your site is slow because of uncompressed images or a heavy theme that a server cannot fix
  • You are buying hosting just for the LiteSpeed name without checking the plan

🏆 The verdict

LiteSpeed is not a marketing trick, but it is not magic either. It is a server that makes a noticeable difference for PHP sites because it builds the cache into the server layer and stays compatible with Apache. And the LiteSpeed Cache plugin is its strongest argument for the ordinary reader: free, widely used and feature-rich, provided you keep it updated and turn on its options carefully.

Our advice for each reader, by their site. Shared hosting customer: choose a company that states LiteSpeed Enterprise on the plan you will buy, and check the header yourself after you buy. VPS administrator with cPanel or Plesk: there is no substitute for Enterprise, so count its license in your costs. VPS administrator with no commercial panel: OpenLiteSpeed with CyberPanel or Enhance is enough for most projects. In all three cases, do not judge a server before you measure your own site rather than the numbers in adverts.

✅ Frequently asked questions about LiteSpeed and LSCache

❓ What is the difference between LiteSpeed and OpenLiteSpeed?

They share the same engine, but OpenLiteSpeed is free and open source and relies on community support, while LiteSpeed Enterprise is commercial and gives you official support, instant reading of .htaccess files, official integration with cPanel and Plesk, and ESI. If your server runs cPanel or Plesk, the supported choice is Enterprise.

❓ What is the difference between LSCache and the LiteSpeed Cache plugin?

LSCache is the cache engine built into the server; it is what actually stores and serves the pages. The LiteSpeed Cache plugin is a WordPress interface that tells the server what to store and when to clear it, and adds tools for optimizing images and files. The plugin alone, without a LiteSpeed server, will not turn on the page cache.

❓ Does the LiteSpeed Cache plugin work on Apache or Nginx hosting?

Partly. The optimization tools, such as image compression, CSS and JS minification, critical CSS generation and lazy loading, work on any server. The page cache needs a LiteSpeed or OpenLiteSpeed server, or the QUIC.cloud CDN service.

❓ Is the LiteSpeed Cache plugin free?

Yes, the plugin is free and open source. But the page cache needs a LiteSpeed server, some editions of which are paid, and some QUIC.cloud services (such as the CDN and image optimization) become paid after a certain usage limit.

❓ Is LiteSpeed faster than Nginx and Apache?

In many WordPress setups it can be, but the gap comes mainly from the built-in cache and not from the server alone. A fair comparison puts each server with its own best cache, and then the gap narrows. In every case no server fixes a heavy theme or uncompressed images.

❓ How do I know whether my host uses LiteSpeed?

Open the browser's developer tools (F12), then the Network tab, and look at the response headers. If you find server: LiteSpeed, it runs on it. You can also use the command curl -I on your site. If your site is behind Cloudflare, the name Cloudflare may appear instead, and then ask support or look for a header that starts with x-litespeed.

❓ Does LiteSpeed support cPanel?

Yes, through a WHM plugin, and LiteSpeed's docs say the cPanel, LiteSpeed and CloudLinux combination is officially supported by all three companies. It lets you install, switch between Apache and LiteSpeed without downtime and manage the cache for WordPress sites in bulk. The customer sees a LiteSpeed Web Cache Manager icon in the Advanced section of their panel after the server administrator installs it. cPanel integration is for the Enterprise edition.

❓ Does LiteSpeed work with Plesk and DirectAdmin?

Yes. LiteSpeed's official installer is tested with cPanel, Plesk and DirectAdmin, and its documentation has installation guides for each. In DirectAdmin you reach the WebAdmin Console from the Extra Features section. Other panels support it too, such as CyberPanel, Enhance and InterWorx.

❓ How much does a LiteSpeed Enterprise license cost?

According to the official pricing page when this was read: there is a free tier for one domain, then the Site Owner plan at $10 a month for five domains, and hosting-company plans with unlimited domains go up to $92 a month for Elite. One-time licenses and a free 15-day trial are available. A shared hosting customer pays none of this, because the host pays it.

❓ Can I use LiteSpeed Cache with WooCommerce?

Yes, the store is officially supported. But LiteSpeed's own documentation points out that some WooCommerce themes may not update the cart correctly with the cache on. So test the cart, checkout and account pages after you turn it on, and exclude from the cache whatever needs excluding.

❓ Do I need QUIC.cloud?

No, it is not required. If your host runs LiteSpeed, the page cache works without it. You only need it if you want its services such as the CDN, image optimization or critical CSS generation, or if your site is on a non-LiteSpeed server and you want to benefit from its cache through the CDN. Remember that your site's data is sent to its servers when you use some of its services.

❓ Should I use LiteSpeed Cache with WP Rocket or another cache plugin?

Do not run two page-cache plugins at the same time, because it creates conflicts that are hard to trace. Choose only one, and if your host runs LiteSpeed, its free plugin is the best fit because it works with the server's cache directly.

❓ Does LiteSpeed support HTTP/3?

Yes, it supports HTTP/3 over QUIC since version 6.0 in 2021, with HTTP/3 turned on by default since 6.0.2, and QUIC v2 since version 6.2. The company relies on the open-source LSQUIC library for it.
