The Apache Software Foundation

provides support for the Apache Community of Open Source software projects, which provide software products for the public good.


Apache projects are defined

by collaborative consensus based processes, an open, pragmatic software license and a desire to create high quality software that leads the way in its field.


We consider ourselves

not simply a group of projects sharing a server, but rather a community of developers and users.
