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; Porter pricing based on vCPU and memory can be expensive for small projects
  • They diverge on capability: Cilium covers eBPF datapath, Porter covers Rapid deployment.

What people use each for

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

Porter

  • Pricing based on vCPU and memory can be expensive for small projects
  • Vendor lock-in to Porter platform despite multi-cloud support
  • Limited customization for complex infrastructure requirements

Can I use Cilium for free?
Yes. Cilium has a free tier, so you can try it without paying. Porter starts at $6/month.
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 Porter is typically brought in for.

Answered from the vendors’ own pages

Cilium: Is Cilium free?

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

Porter: How is Porter priced?

Porter uses pay-as-you-go pricing: $6 per month per GB of RAM and $13 per month per vCPU. You only pay for the resources your applications use, not cloud instance capacity.

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.

Porter: Does Porter include cloud provider costs?

Porter pricing excludes underlying cloud provider costs (AWS, Azure, GCP), though cloud credits can offset those expenses.

Source
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.

Porter: Do startups get special pricing?

Yes, nonprofits receive 50% off standard rates, and startups may qualify for special pricing programs.
