Jenkins
Jenkins is an open source automation server that enables developers around the world to reliably build, test, and deploy their software. It provides hundreds of plugins to support building, deploying, and automating any project.
Jenkins — Open Source CI/CD Automation Server (2026)
Jenkins is the most popular open-source CI/CD server with 1,800+ plugins. Pipeline-as-code, distributed builds, and integration with every dev tool.
What is Jenkins?
What Is Jenkins?
Jenkins is the most widely used open-source automation server for continuous integration and continuous delivery (CI/CD). It automates building, testing, and deploying software, enabling development teams to integrate code changes frequently and catch issues early.
Key Features
Jenkins supports pipeline-as-code through Jenkinsfiles, which define build, test, and deployment stages in a version-controlled script. It offers over 1,800 plugins for integration with virtually every development tool — Git, Docker, Kubernetes, AWS, Slack, Jira, and hundreds more.
The distributed build system can spread work across multiple machines for faster execution. Jenkins supports parallel stages, conditional execution, and manual approval gates in pipelines. The Blue Ocean interface provides a modern visualization of pipeline execution.
Pricing
Jenkins is completely free and open source under the MIT license. CloudBees offers a commercial distribution with enterprise support, security features, and managed hosting.
Jenkins vs GitHub Actions
Jenkins offers maximum flexibility and self-hosted control. GitHub Actions provides tighter GitHub integration with less maintenance overhead. Jenkins is preferred by enterprises with complex pipelines and on-premise requirements; GitHub Actions suits teams already on GitHub who want simpler CI/CD.
