Apache License 2.0

A permissive license with an express patent grant and clear rules for notices and modifications.

Compared to common options: More ceremony than MIT/BSD; prefer when an explicit patent grant and NOTICE handling matter.

Generally allows

  • Commercial use
  • Modification
  • Distribution
  • Patent use
  • Private use

Typically requires

  • Include license and NOTICE files
  • State significant changes
  • Retain copyright, patent, trademark, and attribution notices

Watch-outs

  • Using trademarks of the project without permission
  • Holding contributors liable

How teams usually use it

  1. Prefer Apache-2.0 when you want an explicit patent license from contributors.
  2. When redistributing, keep NOTICE contents and document your own modifications.
  3. Do not assume trademark rights to project names or logos are granted.
