Argo CD vs Concourse

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.

Concourse is an open-source CI/CD platform that models continuous integration as simple, reusable, isolated tasks to build modular and composable pipelines. It provides a declarative approach to pipeline management with strong isolation guarantees.
