Is Unity Considered Open Source?

▶

Unity is not considered open source, as it is a proprietary game engine developed by Unity Technologies, although it does offer some open-source features and tools, such as Unity Machine Learning Agents, which is open-source software that connects the Unity platform to machine learning programs, including Google’s TensorFlow. The Unity platform is available in both free and paid versions, with the free version being suitable for individuals and small organizations with less than $100,000 in revenue and funds raised in the last 12 months.
