This page lists, and gives links to, the various licenses that are available for Saxonica products. Further information can be found in the Saxon documentation.
A free 30-day evaluation license is available. The terms and conditions for this license are available here:
The evaluation license currently gives access to all functionality (Saxon-EE and Saxon-PE). Note that when running with an evaluation license, Saxon will occasionally insert random asterisks into the output of a transformation or query. This is designed to ensure that the software is not suitable for production use.
For paid-up licenses, the terms and conditions can be found here:
Site licenses are also available. The terms and conditions (including the definition of a "site") can be found here:
A license that allows redistribution of Saxon-PE or Saxon-EE with an application is available on request. The standard terms and conditions can be customised to meet specific contractual requirements; they can be found here:
With the first major release of Saxon/C 1.0.0, the full range of Saxon editions (Home, Professional and Enterprise) are available for the C/C++ and PHP programming languages (and Python, from the Saxon/C 1.2.0 release), as they are for the Java and .NET platforms. The licensing for the Saxon/C editions Saxon-HE/C, Saxon-PE/C and Saxon-EE/C is the same as for the corresponding standard edition (that is, Saxon-HE, Saxon-PE and Saxon-EE, respectively).
See above for license information for the commercial products Saxon-PE and Saxon-EE, and below for the open-source product Saxon-HE.
