What Is Open Source and How Does It Work?

Open Source Basics Explained

To understand open source software, it’s important to grasp a few foundational ideas that make this collaborative development approach both functional and impactful.

What is Source Code?

Source code is the set of instructions written by programmers in languages like Python, HTML, C++, or Java. Think of it as the blueprint that guides the creation, maintenance, and evolution of software.

The key distinction between open source and proprietary software lies in access. Open source code is freely available for anyone to view, modify, and share. On the other hand, proprietary software keeps its source code private, with strict limitations on who can access or alter it. This openness in the code fosters customization, troubleshooting, innovation, and even improved security by enabling a broader community to contribute and identify vulnerabilities.

To ensure quality, open source projects often implement rigorous review processes, ensuring that the collaborative nature of development doesn’t compromise the software’s reliability.

How Does Open Source Work?

Open source projects thrive on structured collaboration. Maintainers oversee contributions, and proposed changes undergo thorough code reviews to ensure they align with the project’s goals and standards. Code reviews, described as "methodical assessments of code designed to identify bugs, increase code quality, and help developers learn the source code" ^[2], are a cornerstone of this process. They not only catch security flaws but also uphold quality and encourage shared learning among developers.

The value of code reviews is widely recognized. In fact, 76% of developers in the 2022 Global DevSecOps Survey rated code reviews as "very valuable" ^[2]. However, as Ibrahim Haddad, VP of R&D at Samsung Research America, cautions:

"If your code review process is overly burdensome, you'll slow innovation or provide a good excuse for developers to circumvent the process completely" ^[3].

Achieving the right balance is critical - ensuring quality without stifling the collaborative energy that defines open source development.

What is Forking?

Forking is one of the most influential aspects of open source software. It involves creating a copy of an existing codebase and modifying it independently ^[4]. Initially, the forked project mirrors the original, but over time, it evolves as developers introduce changes. Forking allows developers to pursue new directions, address stagnation in the original project, or explore alternative visions without requiring permission from the original creators.

A notable example is MariaDB, which forked from MySQL and grew into a vibrant community of nearly 400 contributors, compared to MySQL’s 100 ^[5]. However, forking isn’t without challenges. As Eric S. Raymond points out:

"The most important characteristic of a fork is that it spawns competing projects that cannot later exchange code, splitting the potential developer community" ^[4].

While forking can drive innovation and new solutions, it may also fragment resources and create additional maintenance complexities.

The influence of open source is undeniable. As of 2023, 96% of all software includes open source dependencies ^[5]. This statistic highlights just how integral open source has become in modern software development, making these concepts essential knowledge for anyone involved in the field.

Common Open Source Software Examples

Open source software plays a foundational role in the modern digital world. Many commercial programs rely on open source code for their functionality, showcasing its widespread influence ^[6].

Well-Known Open Source Projects

Several prominent open source projects serve as prime examples of how collaborative development shapes technology. Linux, introduced in 1991, stands as the largest open source project globally ^[8]. It powers much of the internet's infrastructure, highlighting its critical role in modern computing.

WordPress demonstrates the power of open source in content management systems. This free platform, built using PHP, supports 41.4% of the top 10 million websites ^[8]. Its open source nature enables developers to contribute themes, plugins, and customizations, fostering a thriving global community.

Web browsers also showcase open source innovation. Mozilla Firefox, launched in 2002, is celebrated for its user-friendly design and smart address bar. It serves as the default browser for many Linux distributions ^[8]. Meanwhile, Brave, a privacy-focused browser, blocks ads and trackers by default, offering users enhanced security ^[8].

For image editing, GIMP provides a robust, open source alternative to Adobe Photoshop. Since its debut in 1996, it has demonstrated how community-driven projects can rival proprietary software ^[8]. Similarly, LibreOffice delivers a full office suite with tools for word processing, spreadsheets, and presentations, standing as an alternative to Microsoft Office 365 ^[8].

VLC Media Player, developed by the VideoLAN Project, supports nearly every media format ^[8]. Additionally, open source software dominates web infrastructure, with over 60% of websites running on Apache and Nginx web servers ^[7].

These examples illustrate how open source software is deeply embedded in everyday technology, serving as a foundation for innovation and accessibility.

How Companies Use Open Source

Major companies leverage open source software to enhance their products and contribute to the broader technology ecosystem. Google, for instance, developed Kubernetes, an open source platform for container orchestration, based on its internal server workload balancing tools ^[10]. Similarly, Microsoft open-sourced .NET Core, with nearly 40% of contributions coming from external developers ^[11]. This collaboration exemplifies how open source fosters innovation and external expertise.

Apple integrates open source components like WebKit into its core technologies. WebKit, the engine behind Safari, originated from the KHTML project and continues to operate under an open source BSD license ^[12].

The financial impact of open source is staggering. Without it, companies would spend an estimated 3.5 times more - around $8.8 trillion - to develop software and platforms ^[6]. The Linux Foundation reports that 70-90% of software codebases today consist of open source elements ^[10].

Open source also plays a strategic role in artificial intelligence. Meta, for example, has embraced open source for its AI projects, including the Llama model. The company stated:

"To ensure that we have access to the best technology and aren't locked into a closed ecosystem over the long term, Llama needs to develop into a full ecosystem of tools, efficiency improvements, silicon optimizations, and other integrations. If we were the only company using Llama, this ecosystem wouldn't develop and we'd fare no better than the closed variants of Unix." ^[9]

This philosophy encourages industry-wide innovation. By 2023, two-thirds of large language models released were open source ^[10], and GitHub reported 100 million developers using its platform that same year ^[10]. Open source technologies now power smartphones, vehicles, aircraft systems, and AI tools that millions interact with daily ^[7].

Is Open Source Software Actually Free?

The term "free" often causes confusion when discussing open source software because it can refer to either the absence of cost or the freedom to use, modify, and share the software's code. Richard Stallman famously clarified this distinction, noting that "free" in open source refers to freedom rather than price, a principle central to the GNU Project ^[20]^[19].

This distinction can be broken down into two concepts. "Free as in beer" describes software that is free of charge but does not grant users the ability to view, modify, or redistribute its source code ^[18]. Examples include Adobe Flash Player and Oracle Java, which are free to use but keep their source code proprietary ^[18]. On the other hand, "free as in speech" refers to software that allows users the freedom to run, study, modify, and distribute the program and its source code. Chromium and Firefox are prominent examples of this type of software ^[18].

The Free Software Foundation emphasizes that "free software" is about respecting users' freedoms and communities, not about price. They state, "The term 'free software' is sometimes misunderstood - it has nothing to do with price. It is about freedom" ^[13]. These freedoms include the rights to run the program, study its code, redistribute copies, and share modified versions ^[19]. However, while these freedoms are invaluable, the practical use of open source software often comes with hidden costs.

The Hidden Costs of Open Source Software

Although open source software typically avoids licensing fees, other expenses can arise. Hosting, maintenance, support, customization, and security are common areas where costs accumulate ^[15]. For example, research by IEEE found that about 64% of open source projects show signs of abandonment. Similarly, a GitHub study revealed that around 80% of repositories are inactive due to a lack of updates ^[14]. When projects are abandoned, users may bear the financial burden of solving issues independently. Customizing open source software for specific needs often requires experienced developers, which can be both expensive and time-consuming. Moreover, the absence of reliable customer support can lead to productivity losses and downtime ^[15].

Security is another critical factor. According to Carnegie Mellon University's CyLab Sustainable Computing Consortium, commercial software contains 20 to 30 bugs per 1,000 lines of code, and open source software is not immune to such vulnerabilities ^[16]. If unpatched, these security flaws can lead to data breaches or regulatory fines. Organizations may also spend between $25 and $139 per developer each month on support packages or automated scanning tools ^[16]. Legal compliance adds another layer of cost, as 85% of audited codebases show license issues that require organizations to implement internal controls ^[16]^[17].

Comparing Open Source and Paid Solutions

Challenges like project abandonment, inconsistent support, and limited functionality can increase the total cost of ownership for open source software ^[14]. In contrast, paid open source solutions often come with a commitment to long-term support, reliability, and stability. Proprietary platforms typically offer robust customer service, detailed troubleshooting guides, and comprehensive training materials. By comparison, open source solutions often rely on community forums and fragmented documentation ^[15].

Despite these challenges, open source software remains a cornerstone of modern software development. As of 2015, approximately 66% of companies built custom software on open source foundations, and developers integrate open source components into 70–90% of modern applications ^[1]. Deciding between open source and proprietary solutions requires a careful analysis of both direct and indirect costs to determine which option aligns best with organizational needs ^[15].

Why Open Source Software Matters

Open source software has become a cornerstone of modern technology, with 92% of modern applications incorporating open source components ^[27]. This widespread use is no coincidence - open source fundamentally reshapes how developers collaborate, how businesses operate, and how technological progress unfolds across industries.

Collaboration and Driving Innovation

Open source software fosters a global community of developers working together. Linus Torvalds' groundbreaking Linux project is a prime example. Linux, which now powers everything from smartphones to supercomputers, owes its success to thousands of developers worldwide contributing their expertise to enhance the operating system. This collaborative model taps into a diverse pool of skills and ideas that no single organization could replicate on its own.

Leading technology companies like Google, Facebook, and Microsoft have embraced open source, actively contributing to and benefiting from this ecosystem ^[21]. These companies recognize that openly sharing certain technologies can accelerate progress for everyone, including themselves.

"Open-source levels the playing field, allowing anyone with a good idea to contribute." - Jimmy Wales, co-founder of Wikipedia ^[22]

The benefits of open source extend beyond innovation. 68% of organizations report cost and time savings, while 31% highlight increased developer satisfaction ^[23]. By building on existing open source foundations, developers can focus on tackling new challenges rather than reinventing solutions that already exist.

For businesses using automation platforms like Latenode, open source components play a crucial role. They enable seamless integrations across 300+ apps without requiring custom development for every connection. By leveraging open source libraries and protocols, platforms like Latenode simplify complex automation workflows, making them accessible even to teams without advanced coding expertise. This collaborative approach not only drives innovation but also promotes stronger, more transparent security practices.

Transparency and Stronger Security

Open source software isn't just about innovation - it also enhances security through transparency. Unlike proprietary software, where the code remains hidden, open source allows anyone to inspect, audit, and improve the code. This openness provides multiple layers of quality and security benefits.

"System security should not depend on the secrecy of the implementation or its components." - US National Institute of Standards and Technology (NIST) ^[24]

When vulnerabilities are discovered in open source projects, the entire community can follow the process of addressing them. For instance, when a flaw is identified in a project like OpenSSL, the community can observe every step - from diagnosis to the final patch ^[26]. This openness ensures thorough fixes and helps prevent similar issues in the future.

The public nature of open source code also allows security researchers worldwide to identify vulnerabilities and contribute solutions. This distributed approach often leads to quicker identification and resolution of security concerns compared to proprietary software, where only internal teams have access to the code.

Transparency isn't limited to the code itself. Open source projects often make their governance and decision-making processes visible. The Kubernetes project, for example, publishes design proposals, meeting summaries, and steering committee decisions ^[25]. Similarly, the Linux kernel relies on a transparent maintainer model, with responsibilities and decision criteria openly documented ^[25]. This openness ensures that technical decisions are made with community input and oversight.

"The trust we place in our digital infrastructure should be proportional to how trustworthy and transparent that infrastructure is." - Biden executive order ^[27]

For businesses, this transparency builds trust in their technology choices. Organizations can thoroughly evaluate open source software before adopting it, gaining a clear understanding of how it works and the security measures in place. 40% of companies prioritize eliminating vendor lock-in by opting for open source solutions ^[23], appreciating the freedom and flexibility that transparency provides.

Additionally, platforms built on open source foundations benefit from the collective expertise of the global developer community. This shared approach to security often results in stronger protection than relying solely on a single company's internal security team.

Why Understanding Open Source is Important

Open source software is now a cornerstone of modern technology, with over 90% of companies incorporating it into their operations ^[28]. Whether you're a business leader, developer, or IT professional, grasping the principles of open source is crucial. It influences competitiveness, streamlines costs, and drives innovation. For companies, this widespread adoption translates into significant savings and strategic advantages.

Consider this: without open source, businesses would face an additional $8.8 trillion in software development costs - spending 3.5 times more to build the platforms and tools that fuel their operations ^[29]. Understanding open source enables organizations to make informed decisions, with 68% of companies citing cost and development time savings as primary motivators. Additionally, 40% of organizations highlight eliminating vendor lock-in as a critical goal ^[23]. This knowledge helps avoid costly missteps and ensures technology investments align with long-term objectives. It's no surprise that 80% of IT departments plan to expand their use of open source software in the coming year ^[29].

"Empowerment of individuals is a key part of what makes open source work, since in the end, innovations tend to come from small groups, not from large, structured efforts." – Tim O'Reilly, Founder and CEO of O'Reilly Media ^[28]

This empowerment not only drives cost savings but also fuels professional growth for developers. Open source expertise is becoming a must-have skill in the tech industry. For developers, contributing to open source projects offers more than just financial rewards - it enhances job satisfaction, broadens skills, and improves career prospects. In fact, 31% of companies report that open source participation helps developers grow professionally ^[23]. Many businesses are also leveraging the open source community to recruit talent and upskill their teams ^[29].

The importance of open source extends beyond individual projects. Developers are increasingly taking the lead in decision-making, shaping the adoption and integration of open source software into company architectures ^[28]. A firm grasp of open source concepts - such as licensing rules and community governance - enables smoother collaboration between technical teams and business leaders.

However, the benefits of open source come with responsibilities. While it offers significant cost savings, it also introduces potential risks, especially if internal expertise is lacking ^[6]. Proper understanding helps organizations address these challenges through due diligence, license compliance, and strong security practices.

Beyond its financial and career advantages, open source fosters a culture of collaborative innovation. As technology continues to evolve, the values of transparency, teamwork, and shared progress embedded in open source are becoming essential for staying competitive. Organizations that embrace these principles are better equipped to adapt, innovate, and build sustainable strategies for the future.

What is forking, and how does it impact open source projects?

Forking refers to the process of creating a new version of an open source project by duplicating its source code. This approach allows developers to explore new ideas, introduce features, or adapt the software to meet specific requirements - all without affecting the original project. By enabling diverse adaptations, forking plays a vital role in driving development and catering to varied user needs.

That said, forking isn’t without its complications. When multiple versions of a project develop independently, it can lead to fragmentation, making collaboration and maintenance across versions more difficult. Additionally, if updates or improvements from a fork are not integrated back into the original project, the two versions can diverge significantly over time - a phenomenon known as "fork drift." While these challenges exist, forking continues to be a cornerstone of creativity and progress within the open source community.
