What is Open Source Software?

smartphone industry writing technology

Open source software is a type of software that is distributed with a license that allows users to access, modify, and distribute the source code. This means that developers can view, use, and change the underlying code that makes up the software, making it an incredibly powerful tool for developers.

Examples of Open Source Software

Here are some popular examples of open source software:

  • Several programming languages (Java, Python, Javascript, C#, Kotlin, PHP, Go…)
  • Several frameworks (Quarkus, Spring, Micronaut, Ruby on Rails, Django, Laravel, Express, Angular, React…)
  • Log4j
  • Hibernate
  • Apache Maven
  • Eclipse IDE
  • IntelliJ IDEA
  • Jenkins
  • JUnit
  • Android
  • LibreOffice

Why Open Source is great?

There are several reasons why open source software is great for developers. Firstly, it allows for collaboration and sharing of knowledge. With open source software, developers from all over the world can contribute to the code, fixing bugs, adding new features, and improving performance. This leads to a better, more robust product that is constantly evolving and improving.

Another advantage of open source software is that it can be more cost-effective. Many open source products are free to use and distribute, which can save a lot of money for businesses and individuals. Furthermore, since the code is open and available for anyone to see and use, it can also save time for developers who can learn from and build upon existing code.

Open source software also provides a level of transparency and accountability. Since the source code is available for anyone to see, there is a level of trust that is built into the software. Additionally, developers can be confident that the software is secure and free from malicious code, as the open source community is constantly reviewing and improving the code.

Finally, open source software provides opportunities for developers to grow and learn. By contributing to open source projects, developers can improve their skills, learn new technologies, and gain exposure to a wider community of developers.


In conclusion, open source software is a powerful tool for developers, providing benefits such as collaboration, cost-effectiveness, transparency, accountability, and opportunities for growth and learning. Whether you are a seasoned developer or just starting, getting involved with open source software can be a great way to improve your skills and make a positive impact on the technology industry.
