🎯 Use Cases

✅ Argo CD Use Cases

Visual GitOps Platform for DevOps teams
Teams new to GitOps needing UI-based onboarding
Centralized App Management across multiple clusters
Progressive Delivery using Argo Rollouts
Integrating with Argo Workflows for full CD pipelines

✅ Flux Use Cases

Microservice-heavy environments with many Git repos
Highly extensible GitOps pipelines using native Kubernetes controllers
Security-first teams needing encrypted secret support (via SOPS)
Cloud-native GitOps at scale with GitOps Toolkit building blocks
Policy-driven deployments with modular architecture

❌ When Not to Use Argo CD or Flux

⚠️ Avoid Argo CD If:

You must minimize resource usage (UI consumes more)
You need SOPS encryption or native secret decryption
You want a completely modular system (Argo is more monolithic)
You do not want to run an in-cluster UI

⚠️ Avoid Flux If:

You want a user-friendly UI with visual status dashboards
You need easy onboarding for less technical users
You rely heavily on manual syncing and hooks visibility
You want tight integration with a GUI-based CD tool

✅ Final Recommendation

Scenario	Recommended Tool
Teams needing rich UI + centralized management	Argo CD
Security-conscious, GitOps-native teams at scale	Flux
Using Helm heavily and need image update automation	Flux
Using GitHub Actions and want Argo Workflows	Argo CD
Needing to integrate with SOPS for secrets	Flux
