Open source

Open source refers to software whose source code is made publicly available for anyone to view, modify, and distribute. Unlike proprietary software, which restricts access and modifications, open source projects encourage collaboration, transparency, and innovation. Developers worldwide contribute improvements, fix bugs, and add features, creating software that evolves rapidly and benefits from community input.

Open source is not limited to free software; while many projects are free to use, licensing terms may vary. Popular examples include Linux, Apache, WordPress, and Python. Open source has become a cornerstone of modern technology, powering operating systems, cloud platforms, web servers, and countless business applications.

Advanced

Open source software (OSS) is governed by licenses such as GNU General Public License (GPL), MIT, and Apache License, which define how the code can be used, modified, and redistributed. These licenses balance freedom of use with obligations like attribution or keeping derivative works open.

Advanced adoption of open source often involves enterprise contributions, code governance, and integration with proprietary systems. Companies may use OSS to reduce costs, accelerate development, and avoid vendor lock-in. Security and quality are maintained through peer review, continuous integration, and community-driven patching. Open source is also central to emerging technologies like Kubernetes, containerization, and artificial intelligence frameworks.
