The Haxe project have several licenses covering the different part of the sources. All of these licenses are well-known open-source licenses. The idea of having several licenses is to permit everybody to use Haxe with no restriction, and to still keep Haxe enhancements open-source.
Here are the different licenses used by Haxe :
- The Haxe compiler is released under the GNU General Public License version 2. This is made to ensure that Haxe will remain open source. The license requires the users distributing modified versions of the Haxe compiler to also distribute the source code, licensed under the same license. Therefor distributing proprietary/closed source forks of the Haxe compiler is not allowed.
The Haxe compiler is entirely written by Haxe author Nicolas Cannasse.
The license of the compiler does not affect the license of your source code. If you use Haxe and the Haxe compiler it is not reqiured that you release your work under an open source license.
- The Haxe libraries are released under a "two-clause" BSD license. This license grants you the right to use the libraries providing only that you include a copyright notice in the end-product. A more liberal license than the GNU General Public License was chosen here, allowing you to use the libraries in proprietary/closed source software.
- The Neko runtime used by Haxe on the server-side is licensed under the GNU Lesser General Public License version 2.1. This license, like the GNU General Public License, requires the users distributing modified versions of the Neko runtime to also distribute the source code, licensed under the same license. However, in some cases the license allows a used to use an unmodified version of the licensed code in proprietary/closed source software.
