Flux CD and Argo CD both implement GitOps for Kubernetes, but they feel very different in day-to-day use.
Flux tends to be more “Kubernetes-native” and configuration-driven, with Git as the source of truth and reconciliation handled via controllers you wire together. Argo CD often appeals to teams who want a stronger UI, clearer app-centric views, and a straightforward “app deployment” experience on top of Git. The right choice usually comes down to team workflow, governance needs, and how you want to manage multi-tenancy and drift.
In the full comparison, we cover:
- Core model and UX differences (controller-driven vs app-centric)
- How each handles multi-tenancy, RBAC, and separation of concerns
- Sync, drift detection, and rollout behavior in real clusters
- Operational considerations: install/upgrade, scaling, and troubleshooting
- When a hybrid approach makes sense (and when it just adds complexity)
