Since JStock is an Open Source project, you may use it free of charge. But please consider making a donation to support the continued development of JStock.

All funds donated to the JStock project will primarily be used to enhance the JStock project. This could include things such as purchasing a domain for the project, buying coke and chips for our developers. All remaining funds will be used to improve our developers work environments, as determined by the project admins. Your donation will make us happy, and encourage us to improve JStock continuously. Thank you very much for your support.
