Jenkins, a long-standing CI/CD tool favored by DevOps teams, is increasingly being considered legacy technology due to its complex setup and scaling requirements, prompting many teams to explore more modern alternatives. These alternatives, such as CircleCI, GitLab CI, GitHub Actions, Atlassian Bamboo, Bitbucket Pipelines, JetBrains TeamCity, AWS CodePipeline, and Buildkite, offer enhanced user interfaces, simplified scaling, and reduced maintenance overhead. While Jenkins remains powerful with its extensive plugin ecosystem and flexibility, it can be resource-intensive to manage, particularly at scale, leading teams to seek platforms that better support collaboration, provide built-in analytics, and offer cloud-based solutions that reduce operational complexity. Each alternative presents unique advantages, such as CircleCI's YAML-based configurations, GitLab CI's integrated repository management, GitHub Actions' ease of setup, and Buildkite's dynamic pipelines, catering to varied organizational needs and infrastructure preferences.
