Open-source software (OSS) is computer software that is released under a license in which the copyright holder grants users the rights to use, study, change, and distribute the software and its source code to anyone and for any purpose. Open-source software may be developed in a collaborative public manner. Open-source software is a prominent example of open collaboration, meaning any capable user is able to participate online in development, making the number of possible contributors indefinite. The ability to examine the code facilitates public trust in the software.

The Tanenbaum–Torvalds debate was a written debate between Andrew S. Tanenbaum and Linus Torvalds, regarding the Linux kernel and kernel architecture in general. Tanenbaum, the creator of Minix, began the debate in 1992 on the Usenet discussion group comp.os.minix, arguing that microkernels are superior to monolithic kernels and therefore Linux was, even in 1992, obsolete. The debate has sometimes been considered a flame war.

Open-source religions employ open-source methods for the sharing, construction, and adaptation of religious belief systems, content, and practice. In comparison to religions utilizing proprietary, authoritarian, hierarchical, and change-resistant structures, open-source religions emphasize sharing in a cultural Commons, participation, self-determination, decentralization, and evolution. They apply principles used in organizing communities developing open-source software for organizing group efforts innovating with human culture. New open-source religions may develop their rituals, praxes, or systems of beliefs through a continuous process of refinement and dialogue among participating practitioners. Organizers and participants often see themselves as part of a more generalized open-source and free-culture movement.
