Is Open Source Software Really Free? Explained Simply
A beginner friendly guide to understanding open source software, licensing, commercial usage, and what “free” actually means.

If you’ve ever searched for open source software, you’ve probably heard this sentence everywhere:
“It’s completely free.”
But is open source actually free in every situation?
Not always.
Some open source software is free to use. Some is free to modify. Some allows commercial usage. And some comes with license conditions many beginners don’t fully understand.
That’s where the confusion starts.
Especially when developers hear terms like: MIT License, GPL, Apache, commercial usage, or proprietary software.
At first, it can feel overwhelming.
But once you understand the basics, open source becomes much easier to understand.
Let’s break it down simply.
What does open source actually mean?
Open source software is software where the source code is publicly available for developers to view, study, modify, and sometimes distribute.
Unlike closed source software, open source projects allow people to understand how the software works internally.
Popular examples include:
Linux
VS Code
Docker
React
Blender
Most modern developer tools today are powered by open source communities.
So… is open source software really free?
Most open source software can be downloaded and used without paying money.
But “free” in open source does not always mean unlimited freedom without conditions.
Open source licenses decide:
how software can be used
whether modifications are allowed
whether commercial usage is permitted
whether redistributed versions must remain open source
That’s why understanding licenses matters.
Can companies make money from open source?
Many successful companies are built around open source software.
Companies make money through:
cloud hosting
enterprise support
premium features
managed services
consulting
Examples include:
Red Hat
Docker
GitLab
MongoDB
Open source does not mean “no business.” It simply changes how companies provide value.
Is open source software safe?
Many beginners assume open source software is unsafe because anyone can view the code.
Ironically, that visibility is often what makes open source more secure.
Because the code is public, developers worldwide can:
review it
report issues
fix vulnerabilities
improve security faster
Of course, not every project is perfectly safe.
That’s why developers should:
use trusted projects
check GitHub activity
read documentation
download from official sources
