Reasons for using FOSS include decreased software costs, increased security against malware, stability, privacy, opportunities for educational usage, and giving users more control over their own hardware. The free software movement and the open-source software movement are online social movements behind widespread production, adoption and promotion of FOSS, with the former preferring to use the equivalent term free/libre and open-source software. FOSS is supported by a loosely associated movement of multiple organizations, foundations, communities and individuals who share basic philosophical perspectives and collaborate practically, but may diverge in detail questions.

Free Software and Open Source Software are two philosophies in software engineering. Free Software and Open Source Software both have common goals of collaboration and innovation but they are distinct in terms of why they are doing it and prioritize different aspects of software development and...

“Free software” means software that respects users' freedom and community. Roughly, it means that the users have the freedom to run, copy, distribute, study, change, and improve the software. The term “free software” is sometimes misunderstood—it has nothing to do with price. It is about freedom. Open Source Software is something that you can modify as per your needs, and share with others without any licensing violation burden. When we say Open Source, the source code of the software is available publicly with Open Source licenses like GNU (GPL) which allows you to edit the source code and distribute it.

Read these licenses and you will realize that these licenses are created to help us. Free software and open-source software are two distinct concepts, each with its own strengths and weaknesses. Free software is developed with the goal of promoting freedom and giving users complete control over the software they use. Open-source software is developed with the goal of producing high-quality software that can be used by anyone, regardless of their technical ability. Ultimately, the choice between free software and open-source software depends on the needs of the user and the specific problem they are trying to solve.

The free software movement has come a long way in forty years. We want to take a moment to thank the people and projects who have helped bring us to this point, and ask for your support in the decades to come.

Help us reach our fundraising goal of $400,000 by January 1, 2026 to keep us strong and steadfast in our continuing work. GNU Operating System Supported by the Free Software Foundation “Free software” means software that respects users' freedom and community. Roughly, it means that the users have the freedom to run, copy, distribute, study, change and improve the software. Thus, “free software” is a matter of liberty, not price. To understand the concept, you should think of “free” as in “free speech,” not as in “free beer.” We sometimes call it “libre software,” borrowing the French or Spanish word for “free” as in...

You may have paid money to get copies of a free program, or you may have obtained copies at no charge. But regardless of how you got your copies, you always have the freedom to copy and change the software, even to sell copies. We campaign for these freedoms because everyone deserves them. With these freedoms, the users (both individually and collectively) control the program and what it does for them. When users don't control the program, we call it a “nonfree” or “proprietary” program. The nonfree program controls the users, and the developer controls the program; this makes the program an instrument of unjust power.

Open Source vs. Free Software: What’s the Difference and Why Does It Matter? In the world of software development, two terms that are often used interchangeably but actually have distinct meanings are "open source" and "free software." While both concepts have their roots in the idea of... In this article, we will explore the differences between open source and free software, why these distinctions matter, and how they impact the software development community. Open source software refers to software that is made freely available to users, along with the underlying source code that allows users to view, modify, and distribute the software. The Open Source Initiative (OSI) defines open source software as having the following characteristics:

Free Redistribution: Users are allowed to redistribute the software to others without any restrictions. Source Code: Users have access to the source code of the software, which allows them to modify and customize the software to meet their specific needs. The term open source refers to something people can modify and share because its design is publicly accessible. The term originated in the context of software development to designate a specific approach to creating computer programs. Today, however, "open source" designates a broader set of values—what we call "the open source way." Open source projects, products, or initiatives embrace and celebrate principles of open exchange, collaborative participation, rapid prototyping, transparency,... Open source software is software with source code that anyone can inspect, modify, and enhance.

"Source code" is the part of software that most computer users don't ever see; it's the code computer programmers can manipulate to change how a piece of software—a "program" or "application"—works. Programmers who have access to a computer program's source code can improve that program by adding features to it or fixing parts that don't always work correctly. Some software has source code that only the person, team, or organization who created it—and maintains exclusive control over it—can modify. People call this kind of software "proprietary" or "closed source" software. Free and open-source software (FOSS) is software that can be classified as both free software and open-source software.[a] That is, anyone is freely licensed to use, copy, study, and change the software in any... FOSS maintains the software user's civil liberty rights (see the Four Essential Freedoms, below).

Other benefits of using FOSS can include decreased software costs, increased security and stability (especially in regard to malware), protecting privacy, education, and giving users more control over their own hardware. Free and open-source operating systems such as Linux and descendants of BSD are widely utilized today, powering millions of servers, desktops, smartphones (e.g., Android), and other devices.[4][5] Free-software licenses and open-source licenses are used... The free-software movement and the open-source software movement are online social movements behind widespread production and adoption of FOSS. "Free and open-source software" (FOSS) is an umbrella term for software that is simultaneously considered both Free software and open-source software. FOSS (free and open-source software) allows the user to inspect the source code and provides a high level of control of the software's functions compared to proprietary software. The term "free software" does not refer to the monetary cost of the software at all, but rather whether the license maintains the software user's civil liberties ("free” as in “free speech,” not as...

Although there is almost a complete overlap between free-software licenses and open-source-software licenses, there is a strong philosophical disagreement between the advocates of these two positions. The terminology of FOSS or "Free and Open-source software" was created to be a neutral on these philosophical disagreements between the FSF and OSI and have a single unified term that could refer to... Richard Stallman's Free Software Definition, adopted by the Free Software Foundation (FSF), defines free software as a matter of liberty not price,[8] and it upholds the Four Essential Freedoms. The earliest-known publication of the definition of his free-software idea was in the February 1986 edition[9] of the FSF's now-discontinued GNU's Bulletin publication. The canonical source for the document is in the philosophy section of the GNU Project website. As of August 2017, it is published there in 40 languages.[10]

This is a list of free and open-source software (FOSS) packages, computer software licensed under free software licenses and open-source licenses. Software that fits the Free Software Definition may be more appropriately called free software; the GNU project in particular objects to their works being referred to as open-source.[1] For more information about the philosophical... However, nearly all software meeting the Free Software Definition also meets the Open Source Definition and vice versa. A small fraction of the software that meets either definition is listed here. Some of the open-source applications are also the basis of commercial products, shown in the List of commercial open-source applications and services. Be advised that available distributions of these systems can contain, or offer to build and install, added software that is neither free software nor open-source.
