Choosing between Cilium and Kuma comes down to understanding what each tool does best. This comparison breaks down the key differences so you can make an informed decision based on your specific needs, not marketing claims.
Short on time? Here's the quick answer
We've tested both tools. Here's who should pick what:
Cilium
Cloud native networking, observability, and security powered by eBPF.
Best for you if:
- • You need cloud & infrastructure features specifically
- • eBPF-based networking, observability, and security for cloud native environments.
- • Provides high-performance data path and granular policy enforcement in Kubernetes.
Kuma
Modern control plane for microservices and service mesh across Kubernetes and VMs.
Best for you if:
- • You need something completely free
- • You need DevOps features specifically
- • A modern, open-source service mesh control plane built on Envoy.
- • Supports both Kubernetes and Virtual Machines, including hybrid and multi-cloud environments.
