What is an example of open source software?

Users searching for examples of open source software will find many popular applications in daily use. Well-known examples include Mozilla Firefox for web browsing, LibreOffice for productivity, and Linux for operating systems, all of which offer publicly accessible source code.

What is an example of open source software?

Open source software is code that is freely available for anyone to view, change, and share. Popular everyday examples include the Mozilla Firefox web browser, the VLC media player, and the WordPress content management system.

These programs power a massive portion of the digital world. Around 43% of all websites on the internet currently run on WordPress. Lets be honest - most of us use open source tools daily without even realizing it. But there is one critical misunderstanding about this software that frequently costs small businesses thousands of dollars - Ill explain exactly what that is in the licensing section below.

When I first started working in tech, I assumed open source meant amateur. I was dead wrong. I spent weeks trying to convince my team to buy an expensive proprietary server OS. The breakthrough came when a senior engineer showed me their Linux setup. It was faster, more secure, and completely free.

Categorical Breakdown of Open Source Examples

To really grasp what software is open source, it helps to look at specific categories. You might be surprised by how many of these you already know.

Productivity and Creativity Tools

LibreOffice is a comprehensive, free office suite that handles word processing, spreadsheets, and presentations as a direct alternative to Microsoft Office. For creatives, GIMP provides a powerful environment for editing images and creating graphics. If you are into 3D modeling, Blender is a professional-grade program used for animation and video creation.

I remember my first time trying to use GIMP after years of Photoshop. My hands practically ached from unlearning all my usual keyboard shortcuts. It took me about three weeks of frustrating trial and error to realize I didnt need to force GIMP to act like Photoshop. Once I embraced its unique workflow, my editing speed actually increased by roughly 20%.

Web, Servers, and Development

Linux is perhaps the most famous example - a highly stable operating system kernel used to power servers, supercomputers, and devices like Android phones. Mozilla Firefox offers a secure web browser strictly focused on user privacy. On the backend, the Apache HTTP Server is a foundational program that hosts millions of websites.

For developers, TensorFlow serves as a robust machine learning framework used for building artificial intelligence models. Rarely do we see a proprietary framework achieve this level of industry dominance so quickly.

The Hidden Catch: Open Source vs. Freeware

This next part is where most people get confused.

Conventional wisdom says that open source simply means free software. But based on my experience helping companies migrate their tech stacks, treating open source exactly like freeware is a dangerous game. Freeware is free to use, but the code remains hidden. Open source gives you the recipe.

Here is that critical misunderstanding I mentioned earlier: open source does not mean without rules. Open source licenses - like the GNU General Public License (GPL) - often require that if you modify and distribute the software, you must make your changes open source too. Businesses often integrate popular open source programs into paid products without reading the license, resulting in messy legal battles and forced code releases.

Open Source vs Proprietary Software Alternatives

Microsoft Office (Proprietary)

• Seamless, built-in integration with OneDrive and Teams
• Closed and completely controlled by Microsoft
• Requires an ongoing monthly or annual subscription fee

LibreOffice (Open Source) ⭐

• Primarily offline, requires third-party setups for cloud syncing
• Open for anyone to inspect, modify, and improve
• Completely free forever with no hidden subscription fees

Adobe Premiere Pro (Proprietary)

• Steep, but backed by massive official documentation
• Ties heavily into other proprietary Adobe applications
• Expensive monthly Creative Cloud subscription

OBS Studio (Open Source) ⭐

• Moderate, heavily supported by community forums and YouTube tutorials
• Relies on community plugins for extended functionality
• Free to download, use, and modify for streaming and recording

Small Business Migration to Open Source

David, a marketing agency owner in Chicago, was paying roughly $2,400 annually for multiple software subscriptions. He decided to switch his five-person team to open source alternatives like GIMP and LibreOffice to cut overhead. He assumed it would be a seamless weekend transition.

By Tuesday, the team was frustrated. The interface differences in GIMP slowed down their graphic designer, and formatting issues popped up when opening older client documents in LibreOffice. Productivity temporarily tanked, and David almost panicked and bought the old subscriptions back.

Instead of reverting, he dedicated Friday afternoon to team training using free community video tutorials. They standardized their document formats to OpenDocument (.odt) and customized GIMP's layout to mimic their previous tools.

Within a month, the team was operating at full speed again. The agency saved over $2,000 in its first year. David learned that migrating to open source requires an upfront investment of time and patience, not just a simple software download.
