Choosing CI/CD tools is still a maintenance-risk decision, not just a feature checklist. This May 2026 view uses the supplied ToolVitals data for open/source-visible CI/CD Tools, including health score, shipping score, openness_label, license_label, GitHub stars, ToolVitals score, and status.
The ranking includes open/source-visible tools only and sorts first by ToolVitals score, with GitHub stars used only as a secondary popularity signal when scores are tied. The list is led by tools with ToolVitals scores of 94, where Jenkins, Dagger, jx, werf, and Superplane are separated mainly by GitHub stars rather than overall score.

Top 3 Highlights
Jenkins ranks first with a ToolVitals score of 94, backed by perfect 100 health and 100 shipping scores.
Dagger ranks second with the same 94 ToolVitals score and matching 100 health and 100 shipping scores. Its description points to an automation engine that can build, test, and ship code locally, in CI, or in the cloud; it is OSI-approved OSS under Apache-2.0 and has 15,787 GitHub stars.
jx ranks third with a 94 ToolVitals score, a 92 health score, and a 100 shipping score. The supplied description places it squarely in Kubernetes CI/CD, with automated CI+CD, preview environments on pull requests, and Tekton-based cloud native pipelines; it is OSI-approved OSS under Apache-2.0.
