Open source software (OSS) is accessible to anyone who wants to view, modify or distribute it. Open source applications can enhance collaboration, efficiency and security. Knowing about OSS can help you find software that meets your needs and has the functionality you require. In this article, we discuss what open source software is, list a few examples, understand its benefits and find out how corporations can effectively use it for their benefit.

What is open source software?

By understanding "What is open source software?" you can better appreciate its advantages and learn how to use it in your project. The idea of open source software is to allow anyone to use, study, change and distribute it. Community members often release new iterations of the software that have improved features or fix bugs through open source collaboration. Programmers can modify the code of an application or program to change its functionality based on use-cases.

In most cases, developers release OSS under a license that enables users to modify it or use it for different purposes based on their requirements and distribute it across multiple computers. Students, individuals, businesses and government agencies can use this software.

Why is open source software important?

The following reasons make open source software important:

  • Since the initial cost is zero or negligible, developers can utilise the codebase and build their own applications. This can save them a lot of money and time.

  • As open source projects are accessible to everyone, they benefit from continuous improvement by developers around the world.

  • Developers build open source based on the principle of flexibility. The license for the project allows developers to modify the source code conveniently. Software that is proprietary has limitations and may not allow for any modifications.

  • Finding and patching vulnerabilities are much quicker and more efficient in OSS.

  • Open source projects emphasise community, collaboration and transparency for the mutual benefit of the users and the platform.

Differences between open source and closed source software

Some differences between open source software and closed source software as are follows:


In many cases, open source software is free to use. Sometimes, OSS may incur some costs for features, additional services and added functionality, but these are minimal. Closed source software carries a cost. This cost varies depending on how complex the software is. Companies offer free trials to convince potential buyers that their software meets their needs.


The question of security is controversial because each piece of software has both positive and negative aspects. Unlike proprietary software, open source software is available for anyone to view, share, modify and test. Upon release, the developers focus on fixing all bugs, checking the code thoroughly and performing rigorous testing before committing it to the repository. Since the source code is available to the public, hackers also have access to it.

Closed source software, on the other hand, can only be fixed by the vendor. The support team receives a support request to resolve the issue. This can increase the turnaround time of the project. Due to its public access and high security, this software is less vulnerable to exploitation.

Source code availability

A major advantage of open source software is the ability to change the source code without any restrictions. A user community allows users to create what they want while benefiting from the innovation developed by others. Having access to the source code allows software developers to improve an existing program. Because of the inaccessibility of the source code, closed-source software is more restricted than OSS.

Support and assistance

Closed source software includes the option of contacting support and getting the issued resolved within a few business days. It includes a detailed and documented response. In case of OSS, there is no direct support available; forums, articles and experts are some alternatives. As a result, there might be a delay in resolving the issue.

User guide and documentation

Users might find it challenging to understand OSS user guides, as they are usually written for developers. In many cases, these user guides do not follow the standard guidelines or structures. The documentation for closed source software includes detailed instructions and is well-written, making it much easier to understand.

Open source licenses

The open source license allows users to use OSS for any purpose they see fit. Users can employ, evaluate, change and release software according to license agreements. The terms of copyleft license stipulate that users share their source code alongside their version of the program in exchange for the free use of the program. Other licenses prevent programmers from charging licensing fees on the versions of the software they develop.

Some popular licenses include:

  • MIT license

  • GNU General Public License (GPL) 2.0

  • GNU General Public License (GPL) 3.0

  • BSD License 2.0

  • Unilicense

What are the benefits of using open source software?

Open source software has several benefits:

Mass adoption

A large number of students, developers, small businesses and governments prefer open source software because of its flexibility, community support, innovation and cost-effectiveness. In recent years, OSS has also achieved reliability, scalability and security, making it a good choice. This has led to increased community support, documentation, regular fixes and other improvements.

Community support

Users can change and incorporate Open source software into their own projects. By increasing the functionality of a program, many users can benefit from it and this can foster collaboration. The open source software community comprises people who develop, test, promote and use open source software. Sometimes community members collaborate on software versions by forming groups and arranging meet-ups.


Using Open source software and technology can accelerate innovation by enabling collaboration, growth and the exchange of ideas. It encourages developers and experts from across the globe to collaborate, build and solve challenging problems. Open source ecosystems form the foundation for many recent innovations in the tech industry, including blockchain, artificial intelligence and big data. This can help in continuous enhancement and improvement of the product. As a result, the community can continuously enhance and improve the product.

Effective training tool

Due to its accessibility, OSS is a valuable resource for people learning to program. The code is available for programmers to study and learn how to design their own programs. Additionally, sharing their work with others and receiving feedback can help them improve their skills. Programmers with more experience can assist learners by pointing out bugs and helping to fix errors so that others can learn from them. A number of forums are available where people can ask questions and receive expert advice.
