The short version

  • Each has a real cost: Linkerd deliberately fewer features than Istio, so complex routing and multi-cluster policy can hit its limits; Zeabur free plan limited to single server with 48-hour log retention
  • They diverge on capability: Linkerd covers Automatic mutual TLS, Zeabur covers AI Agent.

Where each one falls short

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

Linkerd

  • Deliberately fewer features than Istio, so complex routing and multi-cluster policy can hit its limits
  • Kubernetes only, with no story for workloads outside a cluster
  • A sidecar per pod is still real memory and latency overhead, however small, and a mesh is another layer to debug during incidents

Zeabur

  • Free plan limited to single server with 48-hour log retention
  • Small team size may limit support and feature velocity
  • Building spec upgrades limited on lower tiers
  • Enterprise support not clearly documented

Answered from the vendors’ own pages

Linkerd: Is Linkerd free?

The open-source project is free. Buoyant, its maintainer, sells enterprise distributions and support separately.

Zeabur: What is included in the free plan?

The free plan includes 1 manageable server, 2C4G build specifications, 48-hour log retention, 50 MB file upload limit, and community support.

Linkerd: Linkerd or Istio?

Linkerd trades features for simplicity, with a smaller proxy and far less configuration. Istio is more capable and correspondingly more work to run.

Zeabur: How do additional seats work on the Team plan?

The Team plan includes 3 seats with additional seats available at $24 per seat per month.

Source
Linkerd: Do I need a service mesh at all?

Only if you need mutual TLS, uniform retries or per-service traffic metrics across many services. For a handful of services it is usually more machinery than the problem justifies.

Zeabur: Is there a free trial period?

The Dev and Pro plans include 14 days free before billing begins.
