Both implement GitOps — Kubernetes state defined in a Git repository.
ArgoCD¶
- Web UI for visualization and management
- Application CRD — declarative definition
- Multi-cluster support
- SSO integration
- Larger community
FluxCD¶
- CLI-first, no UI (but Weave GitOps dashboard)
- Native K8s controllers
- Helm, Kustomize, OCI support
- Lighter, less resource overhead
- CNCF graduated project
Comparison¶
- UI: ArgoCD ★★★, FluxCD ★☆☆
- Complexity: ArgoCD more components, FluxCD simpler
- Multi-cluster: ArgoCD better
- Helm support: both good
- Resource usage: FluxCD lower
ArgoCD for UI, FluxCD for Simplicity¶
ArgoCD if you want UI and multi-cluster. FluxCD for lightweight GitOps.
