Flux vs Argo CD

Same catalog, two overlapping tools. Catch and verdict side by side. No winner score.

Flux

Apache-2.0 CNCF GitOps Toolkit for Kubernetes

Apache-2.0 · open-source

The Catch

K8s-only GitOps Toolkit; not Kamal/Coolify VM PaaS. You need a working cluster plus RBAC plus secrets story. Prefer current Flux Operator docs over legacy bootstrap blogs.

Verdict

Apache-2.0 K8s GitOps. Free on-cluster; not a VM deploy tool.

Argo CD

Apache-2.0 CNCF declarative GitOps CD for Kubernetes

Apache-2.0 · open-source

The Catch

Vs Flux: UI/app-centric GitOps CD lane, not Flux Toolkit. Still K8s-only. You run the control plane, secrets, and promotion story. Not Kamal/Coolify for VMs.

Verdict

Apache-2.0 GitOps CD. Free on-cluster; Flux is the toolkit cousin.
