Top Open Source Software Examples Popular in 2023
Table of Contents
It almost feels like there’s an app for everything these days. The worst part is that a lot of apps are created for very niche or specific purposes, which means you’ll need all sorts of apps for all sorts of things. As your need for programs increases, you may find that you’ll also have to start spending more money buying software outright or for maintaining subscriptions to certain services.
With so many costs associated with software, it only makes sense that people now look for free alternatives. And that’s where open source comes in.
To help you reduce the strain on your wallet, we listed some of the best open source software examples available in 2023. Let’s get started!
What is Open Source Software? [Definition]
The simplest way to describe open source software is that it is computer software (i.e. programs and applications) released under specific licenses. These licenses allow users to use the open source programs at no cost. It also allows a few other things — for example, users can inspect an open source software’s source code. Users can also freely contribute to open source project or make improvements upon certain software. And finally, users can also freely distribute open source software and anything that they build on top of it.
Chromium is a great example of open source software. On its own, Chromium was made as a browser project aiming to provide a faster, safer, and better browsing experience to users. Because it is open source, people were able to look at its source code. People began to make alterations and modifications and even started to build on top of Chromium’s source code. The result? You have browsers like Google Chrome, Microsoft Edge, and Brave Browser, all built from Chromium.
Why Use Open Source Software?
If you’re wondering why you should consider using open source software, here are a few reasons:
- Cost - One of the first and biggest reasons why people choose to use open source software is the cost savings. Open source software is typically free, although many projects welcome (completely voluntary) donations for support.
- Security and Stability - In most cases, open source software gets a lot more people looking at it, which means people also tend to spot more vulnerabilities and issues which can then get fixed.
- Community - Most open source software are supported and maintained by a growing community of people who use, test, modify, improve, and review the software. It is relatively easy to find support if you run into issues while using open source applications.
- Control - Open source software allows you to look at its source code, so you can see exactly what a program does — or even alter how it works if you know how.

Special Mention: Open Source Blockchain Software
Put simply, Blockchain is a system through which transactions are recorded. Each time a transaction occurs, information is then documented (typically on a spreadsheet). All of the participants can then access these spreadsheets and records.
Blockchain is completely open source, which means that it is open to community involvement and contributions. It is secure and is most widely used in the financial sector. However, it’s now starting to gain ground in other industries, such as eCommerce, e-governance, online voting, and more.
Below, you’ll find a few of the most popular open source examples for Blockchain:
Although Ethereum is now more widely known as one of the biggest cryptocurrencies (much like Bitcoin), it is actually also software that brings users and businesses together, helping in the creation of “smart contracts.” Ethereum’s development team is constantly updating and improving upon it with the goal of providing an even better user experience.
Ripple generally helps businesses to manage financial transactions. It ensures that data is secure while it connects banks and companies with various service providers worldwide.
Hyperledger helps businesses on the enterprise level to keep global transactions more secure. It is a platform focused on the goal of improving cross-platform blockchain technologies.
Open source software can really empower people’s daily lives. It can encourage budding artists and musicians to create, or push tech-interested people into the world of programming and computer science. There’s a vast sea of open source software available in the world today. We hope that this list of some of the best open source software examples has helped you find a few gems!
