ExSite is available under either a commercial software license, or a free software license.
Commercial Software License
ExSite is maintained and supported by Exware Solutions, Inc. Exware provides support guarantees to its clients, including but not necessarily limited to upgrades, bug fixes and patches, customizations, new module development, software porting, hosting services, and the like.

Free Software License
ExSite may be used (run, copied, redistributed) under the terms of the GPL. You have many freedoms in how you use the software with this license, but there is no guarantee of support, nor any warranty of any kind. This license may nevertheless be suitable for DIY web developers. (Note that particular web application plug-ins may carry their own licensing terms. Do not assume that a given plug-in also carries GPL licensing without consulting its documentation.)
ExSite functions as an Operating System for your website. Like a conventional operating system, it has a user interface, a kernel that provides basic system services, utility programs for administering the system, and an API that allows 3rd-party applications to run on it. It is important to understand the different roles these components play to understand the licensing terms of ExSite.
ExSite files and programs are released in two or more distributions:
In addition to the Free Software licencing terms outlined above, ExSite is also available under commercial licenses with full support and other benefits. Contact Exware Solutions, Inc. for more information on these alternate licensing arrangements.
Licensing of Web Application "Plug-ins"
The GPL is not specific about whether a "plug-in" module is part of a combined work (which would fall under the same license) or an independent work that is separately licensed. It is the wish of the ExSite copyright holders that plug-in web applications can optionally carry their own separate licencing terms.
For further clarity, therefore, the following addendum to the GPL is applied to the ExSite base distribution:
Note that if a web application does not specify its own licencing terms as outlined here, then it defaults to the GPL.
