Use when

Platform teams standardizing on GitOps for Kubernetes deployments, especially across many clusters where drift is a real risk.

Avoid when

Small teams running a single cluster — a straightforward CI pipeline with kubectl apply is simpler and has far fewer moving parts.

What is Argo CD?

Argo CD is a CNCF graduated project that pulls manifests from Git and reconciles them against live Kubernetes clusters. It provides a UI, CLI, and API showing drift between desired and actual state, and supports progressive delivery via Argo Rollouts. Widely adopted at companies running large fleets of clusters — the de facto GitOps controller paired with Flux as the main alternative.
