Apache License 2.0

Also known as: Apache License 2.0 / ALv2 / Apache 2.0

Permissive OSS license like MIT but with explicit patent grant and termination clauses. Adopted by TensorFlow, Kubernetes, and Android AOSP.


Overview

Apache License 2.0 is a permissive OSS license without copyleft, allowing unrestricted commercial use. The key difference from MIT is its patent clause: contributors grant users explicit patent rights, which terminate if the user sues for patent infringement.

Comparison with GPL and MIT

GPL requires source disclosure (copyleft) and is less suitable for commercial products. Both Apache 2.0 and MIT are business-friendly, but Apache 2.0 is chosen when patent risk is a concern. For software selection guidance, see the business system development guide.
