The difference between open-source and proprietary software lies in their licensing models and user rights. Open-source software is released with a license that allows users to view, modify, and distribute the source code freely, fostering community collaboration and innovation. In contrast, proprietary software is owned by an individual or company, restricting access to its source code and limiting users’ rights. Proprietary software typically requires users to purchase licenses and may not allow modifications, whereas open-source alternatives promote transparency, customization, and community-driven development.
