Open Source Initiative

Open source initiative is a nonprofit organization that defines open source software. It provides the user with access to the software and the source code, through which the software can be rewritten easily as per the needs without much complication. But open source is not just about the code; it is also the support from the communities, collaborations from the programmers, and innovation.

Mozilla Firefox

Mozilla Firefox is a browser developed by Mozilla Open Source Support (MOSS). It provides thousands of plugins that you can work with. It offers many functionalities such as security and privacy checks such as blocking crypto mining scripts and social trackers, and utilities like web extensions, autoplay blocking, text to speech, and many more.

Python Software Foundation

Python Software Foundation (PSF) is also a nonprofit corporation that gave birth to the python programming language, which is now one of the best programming languages in computer science. Python is widely popular for its support and community. Nowadays, Python is gaining so much popularity that it is being used in most the firms that work with data analysis and machine learning. Also, most of the libraries and frameworks available for Python, like OpenCV, Django, and TensorFlow, are open source and free of cost.

Frequently Asked Questions

  1. Is Google open source?
    Open source organizations provide their projects free of charge and provide their source code to the user to modify it as per their requirements. In google, almost all the products are either paid or subscription-based. And it doesn’t provide source code with the products as well. So no, Google is not an open-source company.
  2. How do Open Source companies make money?
    As it is known that open source projects are free of charge, but these companies need to pay their employees and handle their other financial expenses. These companies follow different business models such as Support, Hosting, Restrictive Licensing, Open core, and Hybrid Licensing.
  3. What do you mean by open source?
    Open source is a term that in computer science originally referred to open source software (OSS). Open-source software is code designed to be publicly accessible, which means anyone can see, modify, and distribute the code as they see fit.
  4. Who owns open source?
    When discussing open source projects, the creator owns the software but provides a license to other “contributors” to reproduce, modify, and redistribute the software. The rights offered to contributors and users of the software are often standardized.


In this article, we have studied open source software and various open source organizations that are creating and managing this software. The list of open sources in computer science is very long, but these are the ones very commonly used.
