By placing an order on this site you are purchasing “developer licenses” for the libraries offered by Olf Software.

Many of these items are open source and available on GitHub under an AGPLv3 license. This license is not compatible with the use and sale of “closed” software, particularly for enterprise or commercial software.

If you wish to use our code libraries and Delphi components in your projects without distributing the source code, you must purchase a license for each developer working on your projects.

We offer lifetime developer licenses that include all future updates of the libraries and components concerned. However, they do not include user support.

If you'd like help in using them, or with specific developments, please contact Patrick Prémartin.
