The short version

  • Each has a real cost: Cilium requires a recent Linux kernel, which rules out older distributions and some managed environments; GitLab baseline requires 8 vCPU and 16 GB RAM for single-node installations; resource-intensive
  • They diverge on capability: Cilium covers eBPF datapath, GitLab covers Git repository management.
  • Prices and features above were last checked on 30 August 2026.

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

GitLab

  • Baseline requires 8 vCPU and 16 GB RAM for single-node installations; resource-intensive
  • PostgreSQL is mandatory; no support for alternative databases
  • Redis or Valkey cache required; adds infrastructure complexity
  • High-availability deployments require inter-node latency below 5 ms; difficult to achieve across geographically distributed sites
  • Requires self-hosting and maintenance; GitLab.com SaaS only available to GitLab team members for administration

Questions people ask

Is Cilium or GitLab better?
Neither clearly leads. Cilium starts at Free and GitLab at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Cilium or GitLab?
Cilium starts at Free and GitLab at Free.
Does Cilium or GitLab run on more platforms?
Cilium runs on Kubernetes, Linux. GitLab runs on Linux, Kubernetes, Docker, Cloud (AWS, GCP, Azure).
Can I use Cilium for free?
Both have a free tier, so you can try either at no cost before committing.
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 GitLab is typically brought in for.
What can Cilium do that GitLab cannot?
Cilium covers eBPF datapath, Identity-based policy, Hubble observability, Sidecar-free mesh. GitLab covers Git repository management, CI/CD pipelines, Issue tracking, Code review.

Answered from the vendors’ own pages

Cilium: Is Cilium free?

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

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.

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.
