Apache Projects

Who Pays?

  • Apache does not pay for development

    • Voluntary contributions only!

  • Many (not all!) developers are paid by a third-party to work on the project

  • Foundation bears indirect support costs

    • Infrastructure, publicity, etc.

We are more than a group of projects sharing a server, we are a community of developers and users.
