Open-source software is defined as software that is freely available for modification, usage, and dissemination. The copyright holder offers permission or control over the source code to anyone who wishes to modify it for next level like to add on additional functionalities. There are different compelling reasons to share something under an open source license, ranging from “more perspectives make better software” to “establishing a standard.” It is critical when developing a sustainable project to consider your reasons for publishing as open source and utilize these as a guide for decision making.

Characteristics of Open Source Software

Some of the key Characteristics of Open Source Software are as follows −

  • Flexibility − Experts can make necessary changes in the software as per their needs.
  • Stability − Availability of technical experts in the open source community to look after the software. Hence, users can make the software stable and can be used for the long term.
  • Security and Reliability − Since the program is being developed and improved by a team of individuals. Thus, software is more secure and reliable.
