Even though LyX is a free program released under the GPL, it costs time and money to develop. If you enjoy using LyX and want to support its development you can make a general donation to the LyX project by clicking on this icon:

There is no minimum sponsorship, any contribution is greatly appreciated.

If you wish to sponsor a specific project, perhaps one that implements the great feature you feel is missing, you can do so by clicking on the icons in the table below. Further down you will find more details on how sponsoring specific projects work. If you still have questions, just ask on the developer's list.

Thank you! — The LyX contributors

Sponsored development rules

All new development happens in trunk (what will become the next stable version).

There are no special commit rules (or exceptions) for sponsored development.

Development is open to anyone.

Payment

Note that the PayPal address is different for each developer. If you already have a PayPal account you can use the PayPal address obtained by clicking on the name of the developer. (replace AT with @.)

We will automatically put your name up on this page as thanks for your sponsorship. If you prefer anonymous sponsorship, please append [ANONYMOUS] to the "item" field of your PayPal contribution. In this field you should also specify the project you want to sponsor

If the minimum amount of money for the project to start is not reached, and if the developer is not willing to proceed, the collected contribution will be automatically donated to the LyX PayPal account unless you appended [NO DONATION] to the "item" field in the PayPal contribution. For the money to be redirected to any other project append [ANY] to the "item" field.

Companies or organizations can contact the listed developer directly if they want to write a regular contract or need an invoice.
