Jenkins is the veteran of the CI/CD world. First released in 2011, it remains the most widely deployed automation server globally. Its plugin ecosystem is enormous — over 1,800 plugins cover everything from cloud deployments to specialized testing frameworks. Jenkins supports both declarative and scripted pipeline syntax, giving teams flexibility in how they define their build processes. The tradeoff is operational complexity: Jenkins requires self-hosting, maintenance, and configuration that newer cloud-native CI tools handle for you. For organizations that need maximum customization and are willing to invest in infrastructure, Jenkins delivers unmatched flexibility.
