What is Jenkins?
Jenkins is the leading open-source automation server for continuous integration and continuous delivery. It runs as a self-contained Java program with packages for Windows, Linux, macOS, and other Unix-like systems, and configures through a web interface with real-time error checking and built-in help. Jenkins' defining strength is its plugin architecture: hundreds of plugins in the Update Center integrate it with practically every tool in a CI/CD toolchain, giving teams nearly unlimited flexibility to build, test, and deploy. It can act as a simple CI server or a full continuous-delivery hub, and distributes work across multiple machines for faster builds and tests. Because it's community-driven and free, Jenkins remains a default for teams that want full control over a self-hosted automation pipeline rather than a managed SaaS.
