Open-source software

Open-source software (OSS) is computer software that is distributed under a license that allows users to use, study, edit, and distribute the program and its source code to anyone and for any purpose.

Open-source software may be created in a public, collaborative environment. Open-source software is a popular example of open collaboration, as any skilled user may engage in development online, increasing the number of potential contributors indefinitely. The ability to see the code promotes public trust in the product.

Open-source software development might bring in viewpoints that are different from those of a particular corporation. According to a 2008 estimate by the Standish Group, the adoption of open-source software models has resulted in annual savings of around $60 billion for customers.

Open source code can be used for research and allows capable end users to adapt software to their personal needs in the same way that user scripts and custom style sheets allow for web sites, and eventually publish the modification as a fork for users with similar preferences, and directly submit potential improvements as pull requests.
