Software whose source code is publicly available under an open license, enabling use, modification, and redistribution.
DESCRIPTION
Open source software is developed and distributed under licenses that allow inspection, modification, and sharing of source code. Communities and foundations govern projects through transparent processes and merit-based contribution models. Licenses range from copyleft (GPL) to permissive (MIT, Apache). Open source accelerates innovation, avoids vendor lock-in, and fosters shared standards. Organizations adopt inner-source practices and contribute fixes upstream to reduce maintenance costs. Compliance requires tracking licenses, obligations, and security patches.
