# What is open-source software?

Open-source software is the kind of software whose code is available to see. <br>The code is not hidden and can be freely inspected - and even modified.

On the other hand, proprietary or closed-source software is the one<br> whose code remains hidden. The ‘proprietary’ adjective stems from the fact that<br> it remains the property of its creator, which is rarely the case with open-source software.

open-source communities are extremely interested in reviewing and proposing<br> changes to the code to make it more secure.<br> Therefore, open-source projects have the advantage of the community. <br>On the other hand, closed-source software has secure codebases, making them less likely to be exploited.
