Argo CD vs Flux CD
Two GitOps controllers — UI-driven vs CRD-native, when to pick each.
| Aspect | 🚀 Argo CD | 🌊 Flux CD |
|---|---|---|
| Model | Application CR + UI/CLI | GitRepository + Kustomization/HelmRelease CRs |
| UI | Rich web UI, app health tree | Minimal UI (Weave GitOps optional) |
| Sync | Manual/auto sync, hooks, waves | Reconciliation loop, health checks |
| Multi-cluster | ApplicationSet, cluster generators | Flux Cluster API / kubeconfig secrets |
| Helm | Native Helm support in app | HelmRelease CR with drift detection |
| Learning curve | Easier onboarding with UI | More Kubernetes-native, YAML-only |
When to use which
Argo CD
Teams want visibility, rollbacks, and app-centric GitOps with a UI.
Flux CD
You prefer CRD-only GitOps, tight Helm/Kustomize integration, and minimal ops overhead.
