Jenkins has played a pivotal role in the evolution of continuous integration/continuous deployment (CI/CD) tools, thanks to its flexible architecture, extensive plugin ecosystem, and widespread adoption. However, its limitations, such as outdated UI, security vulnerabilities, and maintenance burdens, are leading organizations like Uber to explore alternatives. Buildkite emerges as a viable option, offering a hybrid model that combines a managed control panel with self-hosted build agents, thus reducing operational burdens while maintaining security and control. Its YAML-based pipeline definitions simplify workflow management compared to Jenkins' Groovy syntax, and decentralized plugin management allows for easier version control. Buildkite’s architecture supports scalable, flexible, and secure CI/CD workflows, making it a compelling choice for enterprises seeking to modernize their build infrastructure without the extensive setup and maintenance overhead associated with Jenkins.
