GPLlike

GPLlike is a term used to describe software licenses that share key characteristics with the GNU General Public License (GPL) but may not be identical. These licenses typically grant users freedoms to run, study, modify, and distribute the software, including its source code. A defining feature often associated with GPLlike licenses is the concept of "copyleft." Copyleft provisions require that any derivative works or modifications distributed under the same license must also be made available under the same or a compatible license. This ensures that the freedoms granted by the original license are preserved in subsequent versions.

While the GPL is the most prominent example, other licenses are considered GPLlike because they embody similar copyleft principles. These might include variations like the GNU Lesser General Public License (LGPL), which has weaker copyleft requirements, or licenses inspired by the GPL's structure and philosophy. Developers and users might refer to a license as GPLlike to indicate its strong commitment to free and open-source software principles, particularly regarding the redistribution of modified code. The exact obligations and permissions can vary between specific GPLlike licenses, making it important to read and understand the terms of each license individually. Understanding these nuances is crucial for ensuring compliance and for making informed decisions about software usage and distribution.
