Jenkins 2026 Community Awards The Jenkins 2026 Community Awards winners have been announced! Congratulations to all the winners and thank you for all of your contributions. Thanks to the community for voting and making this possible. Meet the driving forces behind Jenkins as we showcase the top contributors shaping the future of continuous integration and delivery. Jenkins Stories! We are looking for experiences of Jenkins users from around the world showcasing how they are building, deploying, and automating great software with Jenkins. Check out their user stories and share yours Participate and Contribute! Jenkins is a community-driven project. We invite everyone to join us and move it forward. Any contribution matters: code, documentation, localization, blog posts, artwork, meetups, and anything else. If you have five minutes or a few hours, you can help! As an extensible automation server, Jenkins can be used as a simple CI server or turned into the continuous delivery hub for any project. Jenkins is a self-contained Java-based program, ready to run out-of-the-box, with packages for Windows, Linux, macOS and other Unix-like operating systems. Jenkins can be easily set up and configured via its web interface, which includes on-the-fly error checks and built-in help. With hundreds of plugins in the Update Center, Jenkins integrates with practically every tool in the continuous integration and continuous delivery toolchain. Jenkins can be extended via its plugin architecture, providing nearly infinite possibilities for what Jenkins can do. Jenkins can easily distribute work across multiple machines, helping drive builds, tests and deployments across multiple platforms faster.
