The Apache Software Foundation

The Apache Software Foundation ( ə-PATCH-ee; ASF) is an American nonprofit corporation (classified as a 501(c)(3) organization in the United States) that supports a number of open-source software projects. The ASF was formed from a group of developers of the Apache HTTP Server, and incorporated on March 25, 1999. As of 2021, it includes approximately 1000 members. The Apache Software Foundation is a decentralized open source community of developers. The software they produce is distributed under the terms of the Apache License, a permissive open-source license for free and open-source software (FOSS). The Apache projects are characterized by a collaborative, consensus-based development process and an open and pragmatic software license, which is to say that it allows developers, who receive the software freely, to redistribute it under non-free terms. Each project is managed by a self-selected team of technical experts who are active contributors to the project. The ASF is a meritocracy, with membership granted only to volunteers who have actively contributed to Apache projects. Among the ASF's objectives are: to provide legal protection to volunteers working on Apache projects, and to prevent the "Apache" brand name from being used by other organizations without permission. The ASF holds several Community Over Code conferences each year, highlighting Apache projects and related technology.
