Open Source Licenses
The licenses listed here meet the requirements of the Free Software Definition and Open Source Definition. They are divided into the following categories according to their licensing characteristics:
- Licenses without Copyleft
- Licenses with Strong Copyleft
- Licenses with Weak Copyleft
- Licenses with Choice Options
- Licenses with Privileges
Software under such licenses may be referred to as Free or Open Source Software. For some of the listed licenses it is controversial or unclear whether these requirements are fulfilled, since the relevant definitions, the free software definition and the open source definition are not identical and license texts are not always clearly written. These licenses are marked with βunclear classificationβ.
Licenses without Copyleft aka Permissive Licenses
Licenses without copyleft are characterized by the fact that they grant the licensee all freedoms of an open source license and do not contain any conditions regarding the type of license to be used for modifications of the software. This allows the licensee to redistribute modified versions of the software under any license conditions, i.e. also convert them into proprietary software.

Licenses with Strong Copyleft
In the case of licenses with a strict copyleft effect, the licensee is obliged to distribute works derived from the original software only under the conditions of the original license. However, the licenses listed here are not necessarily βGPL-compatibleβ.
GPL-style Licenses
The licenses listed here contain the different GPL versions and derived license texts. There are also some GPL variants with exceptions from the strong copyleft. These licenses with exceptions are then to be understood as weak copyleft, but are listed here for the sake of a better orientation.

Licenses with Weak Copyleft
Licenses with weak copyleft have a copyleft effect, which does not include all derived works, but contains defined exceptions.
MPL-style Licenses
MPL-style licenses have file-based Copyleft, i.e. if modifications of the software are implemented in separate files, these files can also be redistributed under other, e.g. proprietary license terms. The aim is to facilitate the combination of software under different license types.

Licenses with Privileges
The licenses with privileges grant the licensees all of the rights that make up Free Software, but at the same time provide special privileges for the licensor in the event of modifications by the licensee. These licenses are mostly used with programs that were originally distributed proprietarily.
