Choose Argo CD if...

Avoid Argo CD if...

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

Choose Flux if...

Platform teams that want a CLI-first, controller-based GitOps foundation and plan to extend or compose with other Kubernetes tooling.

Avoid Flux if...

Teams that value a polished UI and out-of-the-box visual dashboards — Argo CD is friendlier for app developers.
