Open source tools in software development are becoming more and more popular every year. This trend is likely to continue as open source licensing achieves new limits of flexibility. Free use of technology has been foundational to a number of software development projects that have changed the way we live, such as the mobile operating system Android. In this article, we explore how and why the software industry has arrived at the open source model, and why businesses should take full advantage of it.

The history of open source software

The tradition of open source goes back to the late 1960s, when the evolution of operating systems and compilers led to increased costs of software development. The industry used a model of bundling software and hardware together to offset the costs of development and support. In other words, software was technically free, yet costly to produce and maintain. Additionally, many customers would have preferred to handle their own software needs rather than pay that price. In 1969, an antitrust suit filed against IBM resolved the situation, calling bundled software anticompetitive.

This led to the rise of restrictive software licenses. In the late 1970s and 1980s, these became the "program products" sold by companies. Bill Gates wrote a letter in 1976, condemning the unlicensed sharing of Microsoft's Altair BASIC product among hobbyist computer users. Businesses stopped distributing the source code of their commercial software.

In the 1980s and 1990s, through the activity of activists like Richard Stallman, software sharing grew as an informal practice. In 1983, Stallman launched the GNU Project, and a first version of the GNU General Public License was published in 1989. In 1991, Linus Torvald started the Linux kernel, then released it under the GNU General Public License a year later as the first complete free operating system.

Finally, in 1998, the free software movement adopted the term "open source", first suggested by Christine Peteroson. Torvalds expressed his approval, and open source took off, gaining traction in the media and the industry.

Open source software development today

In 2017, 66% percent of organizations were happy to support team member contributions to open source projects. More recent data from Statista shows that global downloads of open source solutions is growing rapidly, having more than doubled from 2020 to 2021 for technologies like JavaScript and Python.

Open source licenses

It is important to understand how an open source license works before utilizing open source tools. Generally, open source licenses require that the program be shared along with its original sources, and that it must retain those characteristics when further distributed or modified. This allows open source software developers to use existing open source code in their own projects, while protecting the original developers' work.

Open source pros and cons

Using open source tools for software development can offer both advantages and disadvantages. On one hand, open source solutions are free to use and there is usually a large community of developers available to help troubleshoot any issues that arise. Additionally, open source technologies are often more secure and reliable than paid solutions.

On the other hand, open source tools may not be up-to-date when it comes to feature sets. Open source developers are usually volunteers, so open source projects can be slow to respond to customer requests or update their offerings. As such, open source is not always the best option for mission-critical software.

Main advantages of open source

Free to use

  • Larger community of developers available for support
  • Usually more secure and reliable than paid solutions
  • Access to source code which allows for more control
  • Better documentation

Main disadvantages of open source

  • Not always up-to-date with feature sets
  • Response time to customer requests or updates can be slow

Open source success stories

In the past decade open source has seen tremendous growth, with open source software powering some of the world’s largest organizations. The most successful open source technologies include programming languages such as Python, JavaScript and Go; frameworks like React and Vue; cloud solutions such as Kubernetes and OpenShift, and development tools like Git.

One example of an open source project that changed the world is the blockchain technology, Ethereum. It is currently being used for cryptocurrency applications, financial services, and other projects that open up new doors of opportunities for developers.
