SaxonJS 2 is free of charge but not open source. The code is the intellectual property of Saxonica, except for the open source components listed in the SaxonJS documentation.
Two licenses are available: the Public License, and the Subscriber License. The Public License is available to anyone who downloads the software, and can be found in the SaxonJS documentation. The Subscriber License is available to those who purchase an annual subscription from the Saxonica shop. As well as traditional support, this provides access to source code, add-on development and debugging tools, and (in due course) additional product functionality. Details of this service and the terms and conditions can be found in the SaxonJS enterprise services product definition and licensing terms.
Although the source code of Saxon-JS 1 is made available, the product is not open source. The code is the intellectual property of Saxonica, except for the open source components listed at Third-party components.
For licensing purposes Saxon-JS 1 is considered to be part of Saxon Enterprise Edition, and purchasing a Saxon-EE license entitles you to use and deploy Saxon-JS 1. The basic model for Saxon-JS 1 is that we charge for development, not for deployment. A Saxon-EE license is required to produce an SEF (stylesheet export file), but no license is needed for run time deployment on a web browser. The Saxon-EE license conditions can be found at Saxon licensing.
