The short version

  • Only Cilium has a free tier, so it costs nothing to try first.
  • Each has a real cost: Cilium requires a recent Linux kernel, which rules out older distributions and some managed environments; MikroTik RouterOS the management interface and overall polish are less refined than enterprise competitors like Cisco or Juniper, and the learning curve for advanced configuration is real
  • They diverge on capability: Cilium covers eBPF datapath, MikroTik RouterOS covers Full routing and firewall stack.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

Cilium

  • Kubernetes networking at a scale where iptables-based CNI performance degradesnot MikroTik RouterOS
  • Network policy expressed on workload identity rather than fragile IP rulesnot MikroTik RouterOS
  • Seeing which services actually talk to each other, and what policy is droppingnot MikroTik RouterOS

MikroTik RouterOS

  • A network engineer or small ISP wanting capable BGP and firewall routing hardware at a lower total cost than Cisco or Juniper equivalentsnot Cilium
  • An organisation that specifically wants to avoid ongoing recurring licence dependency for core routing hardwarenot Cilium
  • A team wanting to run RouterOS as a virtual router in the cloud (CHR) with its own separate perpetual licensing tiersnot Cilium
  • A hobbyist or small business self-managing network infrastructure without a vendor support contractnot Cilium

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Cilium

  • Requires a recent Linux kernel, which rules out older distributions and some managed environments
  • eBPF is genuinely hard to debug when it misbehaves, and the skill is rare on most teams
  • Broad scope — CNI, policy, mesh, observability — means the learning curve covers several domains at once

MikroTik RouterOS

  • The management interface and overall polish are less refined than enterprise competitors like Cisco or Juniper, and the learning curve for advanced configuration is real
  • Formal vendor support is thinner than what an enterprise buyer gets from Cisco or Juniper; community forums and documentation are the primary self-support resource
  • Feature and licence-level naming (Level 3 through Level 6, and separately Free/P1/P10/P-Unlimited on CHR) is confusing enough that buyers commonly need to research which level a given deployment actually requires
  • Perpetual licensing on hardware, while avoiding a recurring fee, also means MikroTik has less ongoing incentive to keep pushing free feature updates to a specific licence level indefinitely, and major version jumps sometimes bring new requirements
  • Hardware build quality and long-term reliability at the low end of MikroTik's range is more variable than higher-priced enterprise-grade routing hardware
  • Security patch cadence and past history of vulnerabilities in RouterOS mean patching discipline matters more without vendor-managed cloud updates the way Meraki or Mist provide automatically

Questions people ask

Is Cilium or MikroTik RouterOS better?
Neither clearly leads. Cilium starts at Free and MikroTik RouterOS at On request, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Cilium or MikroTik RouterOS?
Cilium has a free tier; the other does not. Paid plans start at Free for Cilium and On request for MikroTik RouterOS.
Does Cilium or MikroTik RouterOS run on more platforms?
Cilium runs on Kubernetes, Linux. MikroTik RouterOS runs on Web.
Can I use Cilium for free?
Yes. Cilium has a free tier, so you can try it without paying. MikroTik RouterOS starts at On request.
What is Cilium best used for?
Cilium is most often used for kubernetes networking at a scale where iptables-based cni performance degrades, network policy expressed on workload identity rather than fragile ip rules, seeing which services actually talk to each other, and what policy is dropping. Of those, kubernetes networking at a scale where iptables-based cni performance degrades and network policy expressed on workload identity rather than fragile ip rules are not what MikroTik RouterOS is typically brought in for.
What can Cilium do that MikroTik RouterOS cannot?
Cilium covers eBPF datapath, Identity-based policy, Hubble observability, Sidecar-free mesh. MikroTik RouterOS covers Full routing and firewall stack, Perpetual licensing, Cloud Hosted Router (CHR), Winbox and CLI management.

Answered from the vendors’ own pages

Cilium: Is Cilium free?

Yes, open source and CNCF-graduated. Isovalent sells an enterprise distribution and support.

MikroTik RouterOS: Does a MikroTik router stop working if I stop paying anything?

No, the RouterOS licence bundled with hardware is a one-time purchase and does not expire or require ongoing payment.

Cilium: What does eBPF change?

It lets Cilium run packet-processing programs inside the kernel instead of relying on iptables rule chains, which behave poorly as the number of services grows.

MikroTik RouterOS: Is CHR licensed the same way as physical hardware?

It uses its own separate perpetual licence tiers (Free, P1, P10, P-Unlimited) rather than the Level 3-6 scheme used on physical hardware.

Cilium: Does Cilium replace a service mesh?

It can cover much of what a mesh does without sidecars, though full mesh feature sets still favour Istio or Linkerd.

MikroTik RouterOS: Can I upgrade a licence level later?

Yes, upgrading to a higher licence level is possible at the price difference between levels rather than buying a new licence outright.
