jenkinsci/jenkins
Summary
Jenkins is the leading open-source automation server built in Java with a large plugin ecosystem (over 2,000 plugins) to automate build, test, and deployment workflows. The page covers release lines (Weekly and LTS), distributions (WAR, Docker, installers), governance, getting started, contributing, and a broad set of resources and community links. This makes it highly relevant for teams adopting CI/CD and DevOps practices, especially those evaluating pipelines-as-code workflows.
