The WTFPL (Do What the Fuck You Want To Public License) is a permissive license most commonly used as a free software license. As a public domain like license, the WTFPL is essentially the same as dedication to the public domain. It allows redistribution and modification of the software under any terms. As of May 2016[update], the WTFPL was used by less than one percent of open-source software projects.
The first version of the WTFPL, released in March 2000, was written by Banlu Kemiyatorn for his own software project. Sam Hocevar, Debian's former project leader, wrote version 2.
The WTFPL intends to be a permissive, public-domain-like license. The license is not a copyleft license. The license differs from public domain in that an author can use it even if they do not necessarily have the ability to place their work in the public domain according to their local laws.
The WTFPL does not include a no-warranty disclaimer, unlike other permissive licenses, such as the MIT License. Though the WTFPL is untested in court, the official website offers a disclaimer to be used in software source code.
The text of the license, written by Sam Hocevar:
The WTFPL is not in wide use among open-source software projects; according to Black Duck Software, the WTFPL is used by less than one percent of open-source projects. Examples include the OpenStreetMap Potlatch online editor, the video game Liero (version 1.36), and extensions. Some files were published under the terms of the WTFPL.
