The Aladdin Free Public License, abbreviated AFPL, is a license written by L. Peter Deutsch for his Ghostscript PostScript language interpreter.

History

edit

The license was derived from the GNU General Public License, but differs on two key points:

  • The source code must be included with any software distribution.
  • The software may not be sold, including any fees involved with distribution.

Deutsch chose to include a commercial restriction in the AFPL based on his observation of people including Ghostscript in commercial products without full license compliance.[2] Recent versions of Ghostscript are not licensed under the AFPL.[3]

Despite the name, the Free Software Foundation does not consider the AFPL a free software license,[1] neither the OSI consider it an open-source license, nor does it fall under the Copyfree Standard definition.[4] The AFPL can be considered a source-available license.

But I saw a number of companies bundling Ghostscript with commercial products while just barely complying with the letter of the GNU license, so I decided that I did not want to make Ghostscript as available for commercial distribution as it would be with the GNU license.
