Company Overview
Jenkins is the world's most widely used open-source CI/CD (Continuous Integration/Continuous Delivery) automation server, created by Kohsuke Kawaguchi during his time at Sun Microsystems. Jenkins was forked from the Hudson project in 2011 (Hudson began in 2005) after Oracle acquired Sun, when the community chose to fork and rename it Jenkins. The project is released under the MIT license and hosted under the CD Foundation / Linux Foundation.
Jenkins is renowned for its vast plugin ecosystem, with 1000+ plugins that integrate with virtually any programming language, version control system, build tool, and deployment platform. It is a core component of DevOps pipelines, widely adopted by millions of developers and enterprises worldwide.
