Definitions

Wikipedia

Open-source software is an antonym for closed source software and refers to any computer software whose source code is available under a license (or arrangement such as the public domain) that permits users to study, change, and improve the software, and to redistribute it in modified or unmodified form. It is often developed in a public, collaborative manner.
