Open Source Software To Know

  • Linux
  • Mozilla Firefox
  • Blender
  • Flutter
  • LibreOffice
  • Python

Is it free? Sometimes, sometimes not. And there is discussion about the difference between free software and open-source software. The principles of freedom as a social value underpin free software, while open-source software is absent any philosophical or ethical underpinnings, states a 2022 post on GeeksforGeeks.org. Free software users can copy, disseminate and change the software; open-source software can be modified without running afoul of licensing agreements, the blog continues. 

Open source software is also not free in another sense: The development of much of it is supported by foundations, for example the Mozilla Foundation’s Mozilla Firefox and the Document Foundation’s LibreOffice. Upon finding the perfect open source software for your project, don’t be surprised to see a “donate” button on the home page.
