Best Free and Open Source Linux Software

Last Updated on December 6, 2025

Open source software is any program where the developer releases the source code for free. Whenever software has an open source license, it means anyone in the world can download, modify and distribute it without paying fees to its original creator.

Open source doesn’t just bestow a “free” download. Many companies develop software without charge but don’t publish the source code preventing other developers improving the code base. By contrast, open source projects are built on the endeavours of many collaborators who give up their time and expertise to create sublime software.

The updates are in accordance with our recent announcement about our plans to massively revamp the site.


The original objective in starting the compilation was to dispel the FUD that Linux does not have the necessary software to compete with Windows. Over time, the aim of the compilation was to enable Linux users, whatever their level of computing experience, to identify software of all types that is worth exploring. With the huge range of open source software available, there is simply not enough time for users to evaluate every application even within a single category of software.

Open source software is often confused with freeware, but the two are very different. Freeware refers to software that users can download and use entirely for free, at no cost. However, they don’t have the right to change the source code.

The opposite of open source software is proprietary software, where only the individual creator/s, or the business who created it, has the right to control or modify the source code.
