Jenkins is the leading open-source automation server built with Java, designed to automate repetitive development tasks and enable teams to focus on work that machines cannot perform. The project provides over 2,000 plugins that support automating virtually any aspect of software development, from building projects and running tests to static code analysis and deployment. Jenkins is trusted by millions of users and adopted by thousands of companies worldwide, ranging from startups to large enterprises, making it a foundational tool in modern software delivery pipelines.
The repository serves as the primary source for Jenkins core development and is actively maintained by a distributed community of contributors. According to GitGenius activity tracking, the project shows significant ongoing engagement with a median issue and pull request response latency of approximately 2,676 hours, though some items experience longer resolution times with a mean latency of 25,952 hours. The most active contributors tracked include timja with 268 events, MarkEWaite with 264 events, and daniel-beck with 219 events, indicating sustained core team involvement in project maintenance and development.
The project maintains two distinct release lines to serve different user needs. The Weekly release line provides frequent updates that include all new features, improvements, and bug fixes for users who want the latest capabilities. The Long-Term Support line offers an older release branch that receives periodic updates through bug fix backports, catering to users who prioritize stability over cutting-edge features. Jenkins distributions are available as WAR files, Docker images, and native packages for multiple platforms including various Linux distributions and Windows.
