Open-source software: what makes it so attractive?


4 min read

You may already be familiar with the term "open source" if you have been involved in programming for some time. Open-source software has gained popularity for many reasons, some of which I will attempt to explain below.


To start with, let's define what open-source software is. Put simply, it refers to programs whose source code is publicly available. This code can typically be accessed through online Git repositories, with GitHub being one of the largest collections of open-source software available.

You're likely already familiar with some examples of open-source software, such as MySQL, Visual Studio Code, Apache HTTP server, Mozilla Firefox Browser, VLC media player, and Linux OS. These programs and operating systems have all been developed using open-source methodologies.

The benefits of open-source software are numerous and extend to developers and businesses.

Better security

One common misconception about open-source software is that it is inherently less secure than closed-source software, as the code is publicly accessible and could be vulnerable to analysis by malicious actors. However, the reality is quite the opposite - open-source software is widely considered to be more secure than its closed-source counterparts.

A prime example of this is the comparison between Windows and Linux operating systems. Windows has been plagued by numerous security vulnerabilities over the years, whereas Linux has a reputation for being more secure.

This can largely be attributed to the "many eyes" phenomenon, in which a greater number of people can analyze the code and identify bugs and security flaws more quickly.


Another major advantage of open-source software is the freedom it provides. With open-source software, individuals and businesses can easily adapt the software to meet their specific needs. This level of customization is not possible with closed-source software, which is often restricted by licensing agreements and proprietary code.

In practice, open-source software enables greater flexibility and control over the software, allowing for a more tailored user experience. This level of freedom is particularly important for businesses, as it enables them to adapt the software to meet their specific needs and gain a competitive advantage in their industry.

Community support

One of the key strengths of open-source software is the strong sense of community that surrounds it. Open-source projects are often supported by large and passionate communities of developers and users, who are dedicated to improving the software and helping others to use it effectively.

This community support can take many forms, including online forums, user groups, and developer communities. These resources provide a wealth of knowledge and expertise that can be invaluable when encountering issues with open-source software. The strength of the community also ensures that open-source software is constantly evolving and improving, as developers collaborate and share ideas to enhance the software's functionality and performance.

For users and businesses, the community support provided by open-source software can be a major advantage, as it ensures that help is readily available when needed and that the software remains up-to-date and relevant.


Another important benefit of open-source software is the transparency it provides. Open-source software is developed in an open and collaborative environment, allowing anyone to view, edit, and review the source code.

This level of transparency ensures that the software is free from hidden features or malicious code, increasing user confidence in the software's integrity. In contrast, closed-source software can sometimes hide unexpected or unwanted features, such as data collection, which can erode user trust and lead to privacy concerns.

By providing full visibility into the code, open-source software enables users and businesses to fully understand how the software works and make informed decisions about its use. This transparency is particularly important in industries such as healthcare and finance, where trust and accountability are critical.

A free alternative

Open-source applications are often created to create an alternative to paid applications. It can also happen that the alternative to commercial applications is even better than the commercial application itself.

These are just a few reasons why open source is so attractive, if you have any other ideas of your own why open source is so attractive, add it in the comments.
