The WTFPL is almost a public domain grant. It is super-permissive. Basically, do whatever you want. Note, however, that it is not a trademark license.

Releases software into the public domain, or otherwise grants permission to use it for any purpose. Disclaims patent licenses.

This license is used for the zlib library and some other open-source libraries/packages. It is very short and very permissive. It requires you to change the name of modified software and contains a sentence removing liability from the authors of the software.

A short, permissive software license. Basically, you can do whatever you want as long as you include the original copyright and license notice in any copy of the software/source.  There are many variations of this license in use.

A highly permissive license nearly identical to the MIT license but with some added trademark restrictions.

You can do anything you want with the software, so long as you include this license and existing copyrights. You can only use this with compatible licenses.

The BSD 2-clause license allows you almost unlimited freedom with the software so long as you include the BSD copyright notice in it (found in Fulltext). Many other licenses are influenced by this one.

The BSD 3-clause license allows you almost unlimited freedom with the software so long as you include the BSD copyright and license notice in it (found in Fulltext).

You can do what you like with the software, as long as you include the required notices. This permissive license contains a patent license from the contributors of the code.

MPL is a copyleft license that is easy to comply with. You must make the source code for any of your changes available under MPL, but you can combine the MPL software with proprietary code, as long as you keep the MPL code in separate files. Version 2.0 is, by default, compatible with LGPL and GPL version 2 or greater. You can distribute binaries under a proprietary license, as long as you make the source available under MPL.

This license, made and used by the Eclipse Foundation, is similar to GPL but allows you to link code under the license to proprietary applications. You may also license binaries under a proprietary license, as long as the source code is available under EPL.

This is the ‘standard’ creative commons license that gives others maximum freedom to do what they want with your work. You must give credit to the original author of the work, state their name and the title of the original work, say that you modified the work if you did and include the attribution logo, found on their website here. Doesn’t allow for Tivoization and provides protection from defamation for the creator.

You may copy, distribute and modify the software as long as you track changes/dates in source files. Any modifications to or software including (via compiler) GPL-licensed code must also be made available under the GPL along with build & install instructions.

This license mainly applies to libraries. You may copy, distribute and modify the software provided that you state modifications and license them under LGPL-2.1. Anything statically linked to the library can only be redistributed under LGPL, but applications that use the library don't have to be.  You must allow reverse engineering of your application as necessary to debug and relink the library.

The AGPL license differs from the other GNU licenses in that it was built for network software. You can distribute modified versions if you keep track of the changes and the date you made them. As per usual with GNU licenses, you must license derivatives under AGPL. It provides the same restrictions and freedoms as the GPLv3 but with an additional clause which makes it so that source code must be distributed along with web publication. Since web sites and services are never distributed in the traditional sense, the AGPL is the GPL of the web.

This license is mainly applied to libraries. You may copy, distribute and modify the software provided that modifications are described and licensed for free under LGPL. Derivatives works (including modifications or anything statically linked to the library) can only be redistributed under LGPL, but applications that use the library don't have to be.

You may copy, distribute and modify the software as long as you track changes/dates in source files. Any modifications to or software including (via compiler) GPL-licensed code must also be made available under the GPL along with build & install instructions.

The no derivatives creative commons license is straightforward; you can take a work released under this license and re-distribute it but you can’t change it. You must give credit to the original author of the work, state their name and the title of the original work, and include the attribution logo, found on their website here. Doesn’t allow for Tivoization and provides protection from defamation for the creator.
