What for?

We want YafaRay to become a useful tool to render our ideas and a real and powerful alternative to proprietary engines. Your donation will help the YafaRay Project to make it possible. Yafaray is currently used by a great community of professionals, proud hobbyists, students and academic institutions for free, as in free speech. We would like to extend this freedom not only to the software, but to all the resources needed to use YafaRay. Only if you don't have time or skills to collaborate with, please consider about donating money. Your generosity allows the YafaRay project to continue. Donations will be used for:

  • Paying for the YafaRay Project's basic expenses, such as hosting and domain registry.
  • Promoting use of YafaRay, through workshops and contests.
  • Community building, through community events and meetings.


Any amount of money you can give is welcome. If you have a credit or debit card, you can donate to the YafaRay Project via Paypal:

If you are having issues donating via Paypal, you may have better results using our alternate payment provider. To donate via a check or money order, please take a look at this page.

Donors will be acknowledged in our Donors page if they agree to be so (a question is made during the donation checkout). Contact our Project Liaison if you have got any question about donating to the YafaRay Project.

Donations of equipment and services.

We rely on the donation of equipment and services from individuals, companies and universities to keep YafaRay connected to the world. If your company has any idle machines or spare equipment lying around, please consider donating them to the YafaRay project. Donors will be acknowledged in our Donors page. Please contact our Project Liaison for details.

Legal framework and commitment to transparency.

YafaRay donations are handled by a legal entity called SPI (SOFTWARE IN THE PUBLIC INTEREST INC) which is an non-profit umbrella organization founded to help projects develop and distribute free open source software and hardware. SPI sponsors renowned projects such as Debian,, PostgreSQL and others:

We have chosen this method because it helps us to handle monetary matters in an honest, aseptic and transparent manner. YafaRay funds must be used as per non-profit organisation's rules. In the meetings agendas of the SPI board anybody has got access to monthly treasurer reports about donations made to our project, amount of YafaRay funds held by SPI and also how much is expended and on which items. Our funds are expent on the most part on hosting, training material for contests and for developers, domain renewal and code sprint expenses in years these events are held.

Apart from the monthly report made by the SPI board, the Yafaray team will report to the Community about how much money is collected and how it is expended.

Tax Information.

The Internal Revenue Service (IRS) of the United States government determined that under section 501 (a) of the Internal Revenue Code, SPI qualifies for 501 (c) (3) (non-profit organization) status under section 509 (a) (1) and 170 (b) (1) (A) (vi). This means that all donations made to SPI and its associated projects (such as YafaRay), should be tax deductible for donors in the United States of America. People or businesses should consult their tax advisor for further information on this matter.
