The short version

  • Each has a real cost: Bruno native Git integration, the feature that distinguishes it from cloud API clients, is Pro only at $6 per user per month; Cilium requires a recent Linux kernel, which rules out older distributions and some managed environments
  • They diverge on capability: Bruno covers API Testing, Cilium covers eBPF datapath.
  • 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.

Bruno

  • Native Git integration, the feature that distinguishes it from cloud API clients, is Pro only at $6 per user per month
  • OpenAPI syncs are capped at 5 a month on the free tier
  • SSO, SCIM and user management require Ultimate at $11 per user per month
  • Private workspaces are a paid feature
  • Advertised prices are annual rates

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

Answered from the vendors’ own pages

Bruno: What is included in Bruno's free tier?

The Open Source plan includes the core API client, limited Git integration, and up to 2 workspaces at no cost. A 14-day free trial of the Ultimate plan is also available without requiring a credit card.

Source
Cilium: Is Cilium free?

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

Bruno: What is the difference between Bruno Pro and Ultimate plans?

Pro ($6/month) includes native Git integration and unlimited workspaces. Ultimate ($11/month) adds SSO/SCIM support, audit logs, 24-hour support (vs. 48-hour), and an account manager. Ultimate supports unlimited OpenAPI syncs while Pro is limited to 5 per month.

Source
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.

Bruno: How much does Bruno Pro save compared to other API tools?

The vendor claims Ultimate saves teams more than 70% versus Postman, though this comparison is promotional rather than a specific cost metric.

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.
