What is Argo CD?

Argo CD is an open-source, declarative continuous delivery tool for Kubernetes that follows the GitOps pattern: application definitions and configurations are stored in Git, and Argo CD continuously monitors running clusters against that desired state. When drift is detected, it can automatically or manually synchronize the live application back to match the Git-defined configuration. It supports multiple templating and packaging tools including Kustomize, Helm, Jsonnet, and plain YAML, and provides a web UI and CLI for real-time visibility into deployment status across clusters. Argo CD is part of the broader Argo project ecosystem and is actively developed by an open-source community, with a growing list of organizations adopting it for Kubernetes deployment automation.
