Google Cloud Deploy vs Kargo

Google Cloud Deploy automates application delivery through an ordered set of target environments. It deploys to Google Kubernetes Engine, Cloud Run, GKE attached clusters, and custom targets, with releases promoted or rolled back through the web console, CLI, or API. Deployment options include canary and parallel rollouts, verification, deploy hooks, and automated promotion. IAM roles and conditions determine which authenticated users and service accounts can act. Cloud Audit Logs and Cloud Logging support audit trails and platform logs. Teams can invoke the service from CI through its CLI or API, including documented GitHub Actions and GitLab connections. Skaffold and Cloud Build render and deploy manifests, alongside artifact repositories and testing or workflow tools. The first active multiple-target pipeline each month costs nothing; each additional active multiple-target pipeline costs $5 a month per billing account. Underlying services may add charges. The regional system limit is 18,000 API requests per minute.

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.
