Argo CD vs CircleCI

Argo CD is an open-source declarative GitOps continuous delivery tool for Kubernetes. It automatically syncs application state in a Kubernetes cluster to match the desired state defined in a Git repository.

CircleCI is a continuous integration and delivery platform that automates building, testing, and deploying code. It provides cloud-hosted and self-hosted runners with support for Docker, Linux, macOS, and Windows builds.
