PSFLab is built by scientists, for scientists. It is free to use for non-commercial research and educational use, and we intend to keep it that way. Forever. But we do incur costs every year for software maintenance and web hosting, which are currently paid from our personal funds.

Please consider donating – give as much as you feel fit, or as much as you can afford. Every bit adds up and contributes to continued software support and development.

Thank you!

A donation will unlock the parallel processing power built into PSFLab, which can significantly speed up calculations on multi-core systems.

The minimum donation is 0.50 USD to cover payment processing fees. Our Terms and Privacy Policy apply.
