The Apache Software Foundation

provides support for the Apache Community of open-source software projects, which provide software products for the public good.


The 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.


Innovation insight from the people and communities behind dozens of Apache projects, from ActiveMQ to Zeppelin: 200+ sessions, 30+ topics, 4 sub-conferences, innovations from the Apache Incubator, community best-practices, The Apache Way, and more. Video presentations now available!

Apache Projects

The all-volunteer ASF develops, stewards, and incubates more than 350 Open Source projects and initiatives that cover a wide range of technologies. From Accumulo to Zookeeper, if you are looking for a rewarding experience in Open Source and industry leading software, chances are you are going to find it here. Are you powered by Apache?
