Automatically run tests and deploy code every time a developer pushes changes to the repository.
Set up a CI/CD pipeline that compiles code, runs security scans, and deploys to production without manual intervention.
Monitor multiple repositories and trigger different build steps based on which branch or tag was updated.
Integrate with cloud platforms and third-party tools to automate your entire software delivery workflow.
Requires Java runtime, Docker setup, and initial server configuration with repository integration before first build can run.
Jenkins is a widely-used open-source automation server written in Java. The problem it solves is the repetitive, error-prone manual work involved in building, testing, and deploying software. Every time a developer saves code, someone (or something) needs to compile it, run the tests, check for issues, and if everything passes, put it on a server. Jenkins automates that entire chain, which is commonly called a CI/CD pipeline (Continuous Integration and Continuous Delivery). Jenkins watches a code repository for changes, then automatically triggers a sequence of steps: compiling the code, running automated tests, scanning for common mistakes, and deploying the result. If any step fails, it alerts the team immediately rather than letting problems accumulate. Jenkins supports over 2,000 plugins, which are add-ons that let it work with virtually any tool, programming language, or cloud platform. You would use Jenkins if your team ships software frequently and wants every code change validated automatically before it reaches users. It can run as a WAR file (a packaged Java application), a Docker container, or an installer on Linux or Windows. Teams of all sizes use it, from startups to enterprises handling large-scale deployments. The two release tracks are a weekly release for the latest features and a Long-Term Support release for teams that prioritize stability.
