Apache License
The Apache License is a permissive free software license written by the Apache Software Foundation (ASF) that allows users to freely use, modify, and distribute software, including for commercial purposes, with minimal restrictions. It is widely used for open-source projects, particularly those hosted by the ASF, and requires attribution, patent grants, and a notice of changes. The license is known for its business-friendly terms, promoting collaboration and adoption in both community and enterprise settings.
Developers should learn about the Apache License when contributing to or using open-source software, as it governs legal rights and obligations for projects like Apache HTTP Server, Kafka, and Hadoop. It is essential for ensuring compliance, understanding licensing compatibility (e.g., with GPL), and making informed decisions about software distribution in commercial products. Knowledge of this license helps avoid legal risks and supports ethical open-source practices in development workflows.
