Harness vs Jenkins
Harness and Jenkins are both ci/cd software. Harness is open source under Apache-2.0, with 39k GitHub stars. Jenkins is open source under MIT, with 27k GitHub stars.
Which to pick
- Pick Harness when
- Your team wants one self-hosted box for code, pipelines and packages instead of stitching GitHub, Jenkins and Nexus together.
- Pick Jenkins when
- You need a self-hosted CI server that can integrate with almost anything, including legacy toolchains, and have someone to maintain it.
Side by side
A self-hosted developer platform combining Git hosting, CI/CD pipelines, cloud dev environments (Gitspaces) and artifact registries in one Docker container. It is the successor to Drone CI.
A long-standing automation server that runs build, test and deploy jobs, extended through more than 2,000 plugins and Groovy pipeline scripts.
Pipeline features are still catching up with Drone, and the open-source edition is a funnel toward Harness's paid commercial platform.
Plugin sprawl makes upgrades and security patching a recurring chore, and the UI and Groovy pipelines feel dated next to newer tools.
