Retina

Microsofts open-source eBPF-based network observability platform for Kubernetes with traffic flow visualization.

-

Our Verdict

Credible open alternative to Cilium Hubble, but Hubble has a head start and broader ecosystem.

Pros

  • Open-source from Microsoft with active development
  • eBPF-based, low overhead on K8s nodes
  • Cloud-agnostic, not tied to AKS
  • Traffic flow visualization for network debugging

Cons

  • Still early vs Cilium Hubble maturity
  • Docs assume Kubernetes networking expertise
  • Limited enterprise support vs commercial tools
  • Overlaps with Cilium/Pixie/Hubble
Best for: Kubernetes network engineers wanting a vendor-neutral eBPF observability tool. Not for: Teams already running Cilium with Hubble or needing polished commercial support.

When to Use Retina

Good fit if you need

  • eBPF-based network traffic visualization for Kubernetes
  • Pod-to-pod traffic flow monitoring without sidecar proxies
  • Detect network policy violations and connectivity issues
  • Open-source Kubernetes network observability from Microsoft
