This is a comparison of published free software licenses.
General comparison
The following table compares various features of each license and is a general guide to the terms and conditions of each license.[1]
Note that a "yes" in either of the last two columns (Link with code using a different license and Release changes under a different license) is not an absolute answer, there may still be restrictions in the license related to this action. You should review the specific license terms[2] and refer to the reference table[1] for more details regarding a "yes" in these columns.
Approvals
This table lists for each license what organizations from the free software community have approved it - be it as a "free software" or as an “open source” license - and how those organizations categorize it. Organizations usually approve specific versions of software licenses.
Notes
- ^1 Was never revised.
- ^2 Compatible with version 3 of the GPL but not version 2.
- ^3 The original version of the Artistic License is defined as non-free because it is overly vague, not because of the substance of the license. The FSF encourages projects to use the Clarified Artistic License instead.[1]
- ^4 Listed as WTFPL.
