The short version

  • Each has a real cost: Cilium requires a recent Linux kernel, which rules out older distributions and some managed environments; Pieces for Developers requires installing and running a background desktop app rather than being purely cloud-based.
  • They diverge on capability: Cilium covers eBPF datapath, Pieces for Developers covers Activity Timeline.
  • Prices and features above were last checked on 29 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

Pieces for Developers

  • Requires installing and running a background desktop app rather than being purely cloud-based.
  • Free tier trial of Pro features requires a credit card and reverts after 7 days.
  • Local-first storage means memory is not automatically synced across multiple machines without Enterprise controls.
  • Effectiveness depends on the breadth of integrations enabled, which adds setup overhead.

Answered from the vendors’ own pages

Cilium: Is Cilium free?

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

Pieces for Developers: Does Pieces store my data in the cloud?

Pieces stores captured data on-device by default, giving users granular controls to pause, disable or delete captures rather than relying solely on cloud storage.

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.

Pieces for Developers: Is there a free plan for Pieces?

Pieces does not offer a permanently free plan; new users instead get a 7-day free trial on any plan, which requires a credit card to start.

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.

Pieces for Developers: What does the Pro plan cost?

Pro is $18.99 per month billed monthly, with roughly a 25% discount available when billed yearly.

Source
Pieces for Developers: What does the Enterprise plan add?

Enterprise costs $22.99 per month (or $69.99 per quarter) and adds organization-wide admin controls, approved AI providers, and governance over captured data.

Source
Pieces for Developers: Can I cancel my Pieces subscription?

Yes, users can upgrade, downgrade, or cancel anytime from account settings, and all plans include a 14-day money-back guarantee.
