'''Open-source software''' is software with source code that anyone can inspect, modify, and enhance. It is distributed under licenses that comply with the [http://opensource.org Open Source Definition]. The open-source model encourages collaborative development, transparency, and peer review, making it distinct from proprietary software where the source code is kept secret.

== History ==
The term "open source" was coined in 1998 by the [[Open Source Initiative]] (OSI) to promote a more business-friendly alternative to the earlier [[free software movement]]. Key milestones include the release of the [[GNU General Public License]] in 1989, the [[Linux kernel]] in 1991, and the [[Mozilla]] project in 1998. The [[Apache Software Foundation]] and [[Eclipse Foundation]] later formalized community governance models. The rise of [[GitHub]] in the 2000s further accelerated open-source adoption.

== Features ==
* Source code is freely available for viewing and modification.
* Licensing types include permissive (e.g., [[MIT License]], [[Apache License]]) and copyleft (e.g., [[GNU General Public License]]).
* Development is often community-driven, with contributions from volunteers and organizations.
* Transparency enables security auditing and rapid bug fixing.
* Many projects follow a release cycle with stable and development branches.

Major examples include the [[Linux]] operating system, the [[Apache HTTP Server]], [[Mozilla Firefox]], [[LibreOffice]], [[Vim]], and the [[Python]] programming language.
