Kargo is an open-source continuous promotion orchestration layer for moving applications through deployment stages in Kubernetes environments. It complements Argo CD, with customizable pipelines for advancing changes from one environment to another and a view of changes across environments. Kargo tracks updates from Git artifacts, container images, Helm charts, and other artifacts. Verification checks can run at stages before an artifact advances downstream. Documented promotion steps include Git operations, Helm, Kustomize, Argo CD, and HTTP requests to external services. Kargo Enterprise additionally lists Jira, ServiceNow, JFrog Evidence, GitHub Actions, and Slack or email notifications, and can automatically return a stage to its last stable artifact when verification fails. The open-source distribution uses the Apache 2.0 license. A basic installation requires a Kubernetes cluster, and the documentation says Kargo works best paired with Argo CD. Its default configuration is suitable only for trying it in a local cluster that is not internet-facing. The open-source distribution has no time- or severity-bound backport guarantee for security fixes. Akuity Pro, including one Kargo instance, is listed at $495 a month; Enterprise pricing is available by contacting sales.
