Donating to JMRI

JMRI runs entirely on volunteer labor. We have an impressive list of people who have worked on JMRI.

However, JMRI also needs contributions of money. We use them to cover the costs of providing the software, and we also need them to help with our legal defense. Your continued support is vital to keeping JMRI available.

If possible, we prefer that you donate via PayPal. Just click on one of the buttons below, which will take you to a PayPal page for making a donation.

[Donate US$10] [Donate US$20] [Donate US$50] [Donate US$100] [Donate US$250] [Pick Amount]

We use the SourceForge donation system for handling donations to JMRI. Unfortunately, in December 2007 they changed to requiring that people create a SourceForge account before directly using that system to donate, which made it significantly more complicated to make a donation. If you have a SourceForge account and want to use that system, click here to login to your account, and then click here to get to the JMRI donation page.

Finally, if you don't want to use PayPal, please contact us directly via email and we can make other arrangements.
