Download files are available for Saxon on C/C++, PHP and Python built for different operating systems. Use the buttons below to download the SaxonC installers for Linux, MacOS, or Windows.

The SaxonC 12 Python extension is available as a wheel package on PyPI. This means that it can be installed with pip (e.g. pip install saxoncee for Saxon-EE), and users no longer need to manually build and install the extension library. SaxonC wheels are available in the three Saxon editions EE, PE, and HE; for Python 3.9 - 3.13; and for Linux, Mac OS, and Windows. See the Saxonica SaxonC PyPI project.
