Argo CD: Pricing, Features & Alternatives

Argo CD is the CNCF-graduated GitOps controller. It watches a Git repository of Kubernetes manifests and continuously reconciles the cluster to match, so deploys are commits, drift is visible, and rollback is a revert. It is free and open source; what it costs you is the cluster it runs on and someone who understands it.
