How cPanel Compares to InterWorx or Plesk
Overall Recommendations
We understand you're busy, so we've distilled everything down to a few key points for you.
InterWorx
Pros
- Inexpensive.
- Offers a single license type that supports all features.
- Full clustering (multi-server) support.
- Robust language and branding support for both the administrative, reseller and end user control panel interfaces.
- There can be multiple server administration accounts with all or limited features.
- End users can create multiple control panel access accounts with all or limited features.
- End users can schedule account backups.
- No ads or feature upsell pestering users.
Cons
- Does not work with Cloud Linux, Ubuntu, Debian or Windows Server.
- No UI for adding/removing Apache/PHP modules.
- Does not support NodeJS, Ruby on Rails, server-side Java, Docker or DNSSEC.
- Doesn't support quite as many third-party add-on products as the other control panels right now.
Overall Cost: InterWorx will be the least expensive to license and it doesn't have lots of complicated licensing options like the other control panels.
Ideal For: Most users looking for a Linux server unless you need one of the services that InterWorx doesn't yet support.
cPanel
Pros
- Currently the most popular Linux server control panel.
- Supports a wide variety of third party add-on products.
- Can handle nearly all server administration tasks via GUI.
- Robust branding support for the end user control panel.
- Support for NodeJS, Ruby on Rails, server-side Java, git version control, and DNSSEC.
Cons
- Very expensive license cost for most people due to per account licensing.
- Some license types do not permit access to all features or may place a hard limit on the number of accounts.
No official unlimited account license available from cPanel, Inc.
HostDime offers an EXCLUSIVE flat-rate cPanel account license when purchased with a server.- No Windows Server, Ubuntu or Debian support. Official Ubuntu support will come in cPanel 100.
- No Docker support.
- The server administration and reseller interface is only available in English.
- Limited branding support for the administrative and reseller interfaces.
- Limited clustering (multi-server) support.
- cPanel and WHM often contain advertisements for other products and services related to cPanel
- cPanel and Plesk are owned by the same parent company.
Overall Cost: cPanel can be very expensive due to the complicated per-account licensing scheme, unless you purchase a license from HostDime with your server.
Ideal For: Users who prefer never to use the command line to administer their Linux server or who have a lot of clients used to how cPanel works.
Plesk
Pros
- Supports a wide variety of server operating systems.
- Standard server license is less expensive than cPanel.
- Second most popular control panel behind cPanel.
- Robust service support for developers (NodeJS, Ruby on Rails, Python, git version control, Docker, ASP .NET*, MSSQL*, Nginx)
* On Windows Server only. - End users can schedule regular backups.
Cons
- Full server license more expensive than InterWorx and some features require additional purchases.
- Some license types may not have access to all features or may limit the number of accounts.
- If you need support for more than one UI language, there is an additional cost.
- Many features require additional purchase. See the charts below for some examples. This can make a Plesk license much more expensive than other control panels if you need all of those features.
- Advertisements appear everywhere for features Plesk tries to upsell to administrators and end users.
- Plesk and cPanel are owned by the same parent company.
Overall Cost: Plesk basic licensing isn't quite as complicated as cPanel, but there are a bunch of "feature packs" that are sold separately and that can make Plesk very expensive.
Ideal For: Users who need a control panel for an Ubuntu, Debian or Windows Server. Also, developers who need access to some of the specialized tools and services (like Docker) that Plesk supports.
Bottom Line
All three control panels are excellent choices, so long as you understand their strengths and weaknesses.

| Web Server Module Installation and Management | ✘ | ✔ | ✔ |
| Web-Based Terminal Application | ✘ | ✔ | ✔ |
Bottom Line: If you want to distribute work across lots of servers all managed by a single control panel, then InterWorx is the best choice as the developers have put a lot of work into cluster support and they continue to work on improving that. InterWorx also has the edge in multiple language support. cPanel has a few more system administration tasks like working with Apache and PHP modules available in the UI than InterWorx does, but only supports American English in WHM. cPanel only fully supports DNS clustering. Plesk supports multiple languages for the administrative/reseller back end, but you have to pay for each additional language you want to add, so that can get expensive if you need to support clients that speak a variety of languages. Plesk does not support service clustering at all, but will allow you to manage multiple Plesk servers from a central location.

Bottom Line: InterWorx ability to allow end users to easily create additional SiteWorx logins with all or a limited subset of features is a big plus here. If your clients have web developers or people who need to manage email only, it is a simple matter for them to create additional accounts with only the appropriate levels of access. cPanel doesn't permit multiple user logins for a single account. Plesk does, but the end user can only select from user roles that the server admin has defined.
