These are examples of FOSS, which stands for Free and Open Source Software.
But FOSS is more than software that costs nothing.
So, what does "free" mean?
Here, free means freedom, not price.
FOSS gives users important freedoms around the software they use. These include the ability to:
Use it for any purpose.
Study it and understand how it works.
Share it with others.
Modify and improve it and share those changes.
This is possible because the source code is available under an appropriate open-source or free-software licence.
Why does open source matter?
Think about the apps and services you use every day.
With proprietary software, the company generally controls the source code. You can use the product according to its licence, but you cannot simply inspect the code, change it, or redistribute your own version.
With FOSS, the relationship is different.
The code can be inspected and improved by a community. Developers can find problems, build new features, adapt software for different needs, and contribute improvements back to the project.
That creates a different model of building software:
One company builds → users consume
versus
People build → people inspect → people contribute → everyone can benefit
Not every open-source project works exactly this way, but collaboration is a major part of the FOSS ecosystem.
Why should you care if you're not a developer?
This is where FOSS becomes more interesting.
1. More control
You are less dependent on a single company deciding what the software can or cannot do.
If you have the technical ability, you can modify the software or hire someone to do it.
2. Transparency
The source code can be inspected.
That does not automatically mean that every FOSS project is perfectly secure or trustworthy. But the ability to inspect and independently review the code creates opportunities for greater transparency.
3. Less vendor lock-in
Imagine your entire workflow depends on one company's software.
If prices increase, features disappear, the company shuts down the product, or your needs change, moving away can be difficult.
Open software can give organisations more options because they can run, adapt, and maintain the software themselves or work with different service providers.
4. You can build on existing work
Developers don't always have to start from zero.
They can take an existing project, understand how it works, adapt it, and build something new on top of it, depending on its licence.
That makes open source a huge foundation for software development.
5. It creates communities, not just products
FOSS projects often bring together developers, designers, students, companies, researchers, and users.
People contribute code, documentation, translations, testing, design, support, and ideas.
This community aspect is one of the most important parts of FOSS.
Is FOSS always free?
No.
This is one of the biggest misunderstandings.
FOSS can be available at no cost, but "free" primarily refers to freedom.
A company can build a business around FOSS by charging for hosting, support, implementation, consulting, customisation, or other services.
The software being open source does not mean there is no business model.
Why is FOSS important for India?
India has a large developer and student community, but open-source culture needs communities, events, funding, mentorship, and opportunities to contribute.
This is one reason organisations such as FOSS United exist.
FOSS United is a non-profit foundation focused on growing the FOSS ecosystem in India. Its work includes local communities, FOSS clubs, grants, events, and initiatives supporting open-source projects.
Its flagship initiatives include IndiaFOSS and FOSS Hack.
The bigger idea
FOSS is ultimately about who has control over technology.
When software is open, people have more opportunities to understand it, modify it, share it, and build on it.
You don't have to be a programmer to care about that.
You just need to recognise that software has become infrastructure for almost everything we do.
FOSS is one way of making that infrastructure more open, collaborative, and accessible.
