How GitLab CI compares with the three variants of Jenkins

This post provides a comparative analysis of GitLab CI against three variants of Jenkins (Legacy, Cloud Native, and Evergreen). It highlights GitLab CI's advantages in terms of extensibility, general-purpose use, community contribution, service stability (automatic restarts vs. manual restarts), brittle configuration (integrated codebase vs. plugin issues), assembly required (convention over configuration vs. complex setup), development velocity (monthly releases vs. weekly), Kubernetes runtime integration (GitLab Runner vs. Knative builder), configuration as code (per-project .gitlab-ci.yml vs. master-level configuration), and secure-by-default design (remote agents vs. Jenkins Remoting Layer vulnerabilities).
