Spinnaker vs Argo CD

Overview

What is being compared

Spinnaker is a multi-cloud continuous delivery platform, developed by Netflix, for complex canary and blue-green pipelines. Argo CD is a Kubernetes-native GitOps tool focused on declarative deployment.

• Origin — Netflix — Kubernetes-native GitOps project
• Targets — AWS, GCP, Azure and Kubernetes — Kubernetes only
• Model — Multi-stage delivery pipelines — Declarative GitOps
• Strength — Complex pipelines across heterogeneous clouds — Kubernetes GitOps workflows
• Deployment strategies — Canary and blue-green built into pipelines — Declarative sync from Git

What upgrading Spinnaker involves

Running Spinnaker means running its services, and upgrades carry real risk: Front50 stores pipeline configurations in S3 or Google Cloud Storage, and a failed migration during an upgrade can lose them.

Greenfield, Kubernetes-only environments should default to Argo CD.
