Open source software has marked its presence in every tech domain today. Moreover, the recent IPO of GitLab and Confluent has tilted the IT- industry towards more developer-centric and open-source software. But what are these open-source software anyway? When a developer creates and releases its source code publicly with a license so that anyone can see, add or modify some functionality, that's when software is termed as open. Most importantly, anyone can download and use them for FREE. It gives extra power to all of us- the developers, users, and especially, the contributors.

When Open Source was introduced in the 90s, the software industry was sceptical about the whole process. However, two decades later, the same companies use Open Source for their products or develop their open-source software (OSS), like Facebook with its React library, Google's Android, and Amazon with AWS. Today, many open-source technology companies such as RedHat, MongoDB, and Cloudera have more than $100 million annual revenue.

Open Source is so popular nowadays. According to some organizations, open-source software contributes up to £43 billion to UK GDP. The latest report claims that top contributors of Open-Source Software (OSS) are from Europe. It ranks fifth as the largest open-source contributor globally.

#Why Use Open Source Software Over Paid Alternatives?

Imagine you bought a new mobile phone and Google started charging you for using Android? It sounds scary? But there are many other paid software in the market that charge money for the same functionality that Open Source Software gives us for FREE.

Open-Source Software (OSS) is known for

● Security

● Affordability

● Transparency

● Consistent

● Interoperability

● Flexibility

● Localization

Take an example of Windows operating systems that are not Open-Source Software and more prone to software virus attacks than Open-Source Software Linux operating systems. People around the world contribute to Linux every day to make more improvements. Here you see how Open Source Softwares work better in Security and Transparency in comparison to paid software.
