How to Choose the Perfect License for LiteSpeed Web Server 2019-04-25 18:18:55 LiteSpeed Enterprise has 8 different licenses to choose from, serving everyone from the low-end hobbyist with a single site to large hosting providers with thousands of clients. Learn more.

Choosing A License

Web Host or Site Owner? Leased License or Owned? Unlimited Domains, or Just One?
There's a LiteSpeed Web Server license to fit any situation. Let us help you find yours.

LSWS Enterprise

The ultimate combination of power and usability. Even more performance features than OpenLiteSpeed. Faster than any other major web server. Requires almost no setup because it automatically reads and uses your existing Apache configurations (including .htaccess files). Compatible with cPanel, Plesk, DirectAdmin, Interworx, CyberPanel, and almost all web applications.

Our Recommendation

Free Starter: Designed for users with their own small sites, and for those new to LiteSpeed who want to give it a try.

Site Owner, Site Owner Plus: These license are aimed toward users with a few sites, or a single large site.

Web Host (Lite, Essential, Professional, Enterprise, Elite): These licenses are meant for hosting companies. We offer a few different options so there is one for every size and type of business.

License Domain Limit Workers RAM Limit
FREE Starter 1 1 2 GB
Site Owner 5 1 8 GB
Site Owner Plus 5 1 Unlimited
Web Host Lite Unlimited 1 8 GB
Web Host Essential Unlimited 1 Unlimited
Web Host Professional Unlimited 2 Unlimited
Web Host Enterprise Unlimited 4 Unlimited
Web Host Elite Unlimited Configurable Unlimited

LiteSpeed Enterprise has 8 different licenses to choose from, serving everyone from the low-end hobbyist with a single site, to large hosting providers handling thousands of clients. These license specifications reflect how much request processing power LiteSpeed Web Server is given.

Other than abiding by the RAM and domain limits of each license, as a rule of thumb, we recommend a license that contains worker processes will make use of about 1/4 of your server's cores.

Domain Limit

The domain limit only refers to top-level domains. Subdomains are unlimited. Add-on domains, providing they are not configured with their own virtual hosts, also do not count toward the limit. If using cPanel, all subdomains must be under the same cPanel account as the top-level domain. Any domains that exceed the specified limit will result in a 403 error.


The number of workers in the license description indicates how many LiteSpeed processes will be spawned - the number of processes that do general server work. Examples of the work done include: routing requests, SSL decryption/encryption, caching, rewriting, serving static contents, etc.

RAM Limit

A server can have any amount of RAM up to the RAM limit for that license type. LSWS will share this RAM with all other processes like normal. Using a license on a server with RAM that exceeds the specified limit will result in an error.

LSCache is included free of charge with all licenses. Starting with the Site Owner license and higher, LiteMage Starter is selectable at no charge.
LiteMage is a caching solution built specifically for Magento stores. LiteMage plugins are available for both Magento1.x and Magento2.x.

There are multiple caching add-ons available for LiteSpeed Enterprise Licenses. These caching solutions greatly reduce the need to serve dynamic pages, and in return greatly reduce system resource usage. For those who haven’t tried LSCache, it is included in the 15-day free trial. The plugins currently available for it are WordPress, xenForo, Magento, PrestaShop, MediaWiki, Drupal, Joomla and OpenCart. Make sure to try it today!


Leased License

Smaller monthly/yearly payments with the ability to update LiteSpeed Enterprise any time at no additional cost. When leasing annually, users pay for 11 months and get the 12th month free.

Owned License

A one time payment with one year of free LiteSpeed Enterprise updates included. If there is a need to update LiteSpeed Enterprise to a newer version after this one year period, future updates can be purchased at a reduced price. This is only applicable to Web Host licenses.

Some Factors To Consider

Have you tried a trial license

We offer free 15-day trial licenses. These licenses are Web Host Professional licenses with LiteMage Unlimited + LSCache. Using a trial license may be a good way to figure out if LSWS is right for you and what type of license and cache solution you may need.

You can always upgrade or downgrade

Often, finding exactly the right license for your usage is a matter of trial and error. Different sites put pressure on different parts of the server. The best approach may be to purchase a license, then try upgrading or downgrading to see if it affects your service noticeably. You can upgrade or downgrade at any time and you will only be charged (or credited) the difference in the license cost for the remainder of the billing period.

What other processes are running on the same server

For example, if you have a 4 core server and run LSWS, PHP, and MySQL on the same server, you will probably be best served by a Web Host Essential or Professional license. LSWS is light enough that it only needs access to 1 or 2 of this server's cores. PHP and MySQL (which are much more resource intensive than LSWS) will be unaffected by this limit and will still have access to all 4 of the server's cores.

Is the content you serve mainly static (such as images, file downloads, etc.)?

Static content is served by LSWS directly, so assigning it more worker processes may help with this. If your server is mainly using PHP or MySQL (for instance, if it is running web applications like WordPress, etc.), giving LSWS access to more worker processes will not help as LSWS is not the bottleneck in these cases.

Do you have a high volume of HTTPS traffic?

HTTPS requires more CPU power for encryption. You may find that giving LSWS access to more worker processes in this case will improve performance. Do not overestimate this effect though. Unless your server only serves static HTTPS, LSWS should still only have access to a fraction of the server's cores.

When to upgrade

A top command will reveal important information about how different processes are using server resources. (LSWS's process is called lshttpd.) A couple of these outputs are useful for determining if the current LSWS installation could benefit from access to more cores:

  • %CPU - Generally LSWS's CPU usage is low. If LSWS's CPU usage starts climbing, and especially if it climbs while the overall load is low, it can indicate that LSWS is hitting a bottleneck and would benefit from access to more cores.
  • %wa - High I/O wait can also be an indicator that LSWS needs more worker processes (and thus access to more cores).

If the %CPU or %wa values are very high, it is best to upgrade to the next license tier. Keep in mind that we allow upgrading/downgrading leased licenses at any time with no downtime.

LiteMage Starter and Standard both have limits on the number of cached objects they can store. To figure out if a higher tier of LiteMage is needed, check the current Cached Object count located under Cache Management in the Magento Admin Panel. If the total is either 1500 ( LiteMage Starter ) or 25,000 ( LiteMage Standard ), it is recommended to upgrade to the next LiteMage tier to support caching more/all pages.

Frequently Asked Questions

Does LSWS work on VPS’s?

Yes, you can use LiteSpeed Web Server on a VPS.

How many servers can I put each license on?

Each license only works on one server (or one VPS).

What is the cancellation policy?

A leased license, or the updates for an owned license, can be cancelled at anytime preventing a renewal invoice from being generated. We do not offer credit/refunds for cancelling.

Do you offer refunds?

We do not offer refunds. If, however, you place a new order and our support team is not able to assist you in getting it set up and running properly, then we do offer a 30-day money back guarantee.


Open source and free. Powerful enough for any website, and easy to configure. Understands Apache mod_rewrite syntax, but requires that you configure it on your own, as it does not automatically read and use Apache configurations.
