Businesses are constantly searching for digital solutions to help them run more efficiently and turn bigger profits faster.
And one common term they may or may not have heard of that can further this agenda is open-source software.
In this article, you will find out what open source software is and get familiar with the most required types.
What’s more, we will also discover the best open source software examples of 2021.
Open-source software is a program that has publicly available code which anyone with technical expertise can use, modify and distribute.
The term open source was introduced in the late 1990s by The Open Source Initiative (OSI).
These type of software solutions don't always solve the same problems. In fact, most open-source software is geared towards different niche solutions.
However, because it is accessible to the general public, it is typically very easy to obtain and incorporate into digital solutions.
Now, it is important to remember that just because open source software is free to use, it doesn't mean that just anyone can use it. Open-source software refers to lines of code (and its variations) that are available.
So, depending on the type of this software, you'll likely still need a qualified software developer to inspect that code, customize the software to your specifications, and integrate it into your current operations.
Very often free source software is used as a synonym with open source software.
Though similar, these two are different types of software.
Both of them offer similar licenses but share different ideologies.
Richard Stallman introduced the concept of free source software back in the 1980s. Its main goal was that all users have the right to operate, copy, share, study, change, and improve this software.
Open source software, on the other hand, was introduced in the late 1990s by a group of individuals as a reaction to the limitations of free source software.
The main difference they presented was that they changed the emphasis from freedom to security. And, they also brought other pragmatic benefits like transparency and cost savings.
All free source software can qualify as open source software. However, not all open source software can be free.
