Whilst 2020 has been quite a challenging year world-wide, the all-volunteer Apache community has demonstrated commendable strength, resilience, and commitment to our tenet of "Community Over Code" — 


  • 238 Apache Projects, sub-projects, incubating podlings, and their communities produced nearly 3,500 releases across dozens of categories. Release Categories: API Gateways, Application Performance Management, Big Data, Blockchain, Build Management Cloud Computing, Content, Cryptography, Customer Profile Platform, Databases, eMail, Enterprise Resource Planning, FinTech, Identity Management, Integrated Development Environments, Integration, IoT, Libraries, Logging, Machine Learning, Messaging, Natural Language Processing, Operating Systems, Programming Languages, Remote Desktop Gateway, Search, Security Frameworks, Servers, Services Framework, Templating, Testing, Version Control, Web Conferencing, Web Crawlers, Web Frameworks, and more.



  • Apache events moved online, and attracted our most diverse and greatest number of participants. ApacheCon@Home drew nearly 5,750 participants from more than 150 countries, who enjoyed 300+ sessions across 27 tracks. A staggering 1.5M+ viewers tuned in to the Apache Roadshow/China over its 2-day online event.

Community/People —http://home.apache.org/


The ASF’s merit-driven "Contributor-Committer-Member" progression is the central governing process across the Apache ecosystem. The core Apache Group of 21 individual Members grew with developers who contributed code, patches, or documentation. Some of these contributors were subsequently granted Committer status by the Membership, and provided access to: 1) commit code directly to Apache repositories; 2) vote on community-related decisions; and 3) propose an active user for Committership. Today, ASF Committers contribute not just code and documentation, but also an array of initiatives that provide value across the greater Apache ecosystem, including Project promotion and community development through mentoring, events, and diversity and inclusion programs. Those Committers who demonstrate merit in the Foundation's growth, evolution, and progress are nominated for ASF Membership by existing members.


The Apache community continues to grow: 


  • We welcomed 3,612 contributors in 2020, 51.87% of whom were newcomers to Apache
  • 905 individuals earned Committer status, totalling 8,022. 
  • 34 individuals were elected as new ASF Members, totalling 813.
