HSL Licensing

HSL Main library

The main HSL library contains our flagship codes and many support routines.

We currently offer three types of licence:

Academic

HSL packages are available at no cost for personal academic research and teaching. See download links for individual packages in the catalogue.

Commercial (per seat)

For use internal to your company we offer per seat licences. Please contact us for pricing. You can download a sample single user licence or small site licence.

Commercial (incorporation)

For incorporation in software that you distribute, we offer an incorporation licence. Pricing is done on a case-by-case basis. Please contact us to discuss your requirements. You can download a sample incorporation licence.

This flowchart may help you decide which licence fits your use case -- if in doubt, please contact us at hsl@stfc.ac.uk.

HSL Archive

The HSL Archive contains many older routines that we are no longer able to fully support, or that have been superseded by newer codes in the main HSL library.

We currently offer two types of licence:

Free personal use

HSL Archive packages are available at no cost for academic or commercial use. This licence is for personal use only, and the software may not be redistributed in whole or in part, as source or in binary form.

Commercial (incorporation)

For incorporation in software that you distribute, we offer an incorporation licence. Pricing is done on a case-by-case basis. Please contact us to discuss your requirements. Pricing is similar to the main library codes due to additional support overheads.
